Zinc die casting is a very efficient process of manufacturing, which is widely used in automobile parts, electronic housing, fittings, hardware, medical equipment, and consumer goods. It is appreciated for its ability to create complex geometries with high-quality dimensional accuracy, clean surface finishes, and high production rates. Despite these benefits, zinc die casting is not a technology immune to quality issues. The defects may occur due to irregularities in the materials used, tool capacity, lack of process control, or design. Good defect prevention, problem shooting, and quality control are critical to ensuring uniform quality in production, reducing scrap rates, and enhancing the overall efficiency of the manufacturing process. This paper will provide an in-depth discussion of the most common defects in zinc die casting, their causes, effective corrective actions, and profile best practices to ensure quality in each production cycle. Quality Problems in Zinc Die Casting The process of zinc die casting involves injecting molten zinc alloy under high pressure into a highly machined steel die. The metal’s solidification rate is fast, resulting in short cycle times and high repeatability. Nevertheless, the high pressure and high speed at which the process operates are the same factors that contribute to both its effectiveness and its susceptibility to defects when the parameters are not monitored. Quality control issues in zinc die casting are often associated with mechanical performance, dimensional quality, surface appearance, corrosion resistance, or assembly fit. Most defects are interconnected, as a single root cause can lead to multiple quality issues. It is important to understand the relationships among material behavior, die design, and processing parameters to enable efficient troubleshooting. Zinc Die Casting Defects Most common defects in zinc die casting can be classified by appearance and their effect on part performance. An overview of common defects and their overall effect is given in the following table. Defect type Appearance Impact Porosity Voids or pinhole internally It will reduce the strength It may cause leakage Cold shuts Visible lines and seams This will result in weak bonding between the flow. Shrinkage Cavities and sink marks The dimensions of the parts change. This will lead to measurement inaccuracies. Incomplete filling Missing or thin sections This will cause the functional failure. Soldering Metal adhering to the die This will cause tool damage Cracks Internal or surface fractures This appearance indicates structural damage or failure. Blistering Bubble-like appearance on the surface Poor surface finish Flash Excess of metal at parting lines The aesthetic appearance will be damaged Porosity in Die Castings Zinc Porosity refers to the presence of empty spaces or gas bubbles in the casting. These cavities can be located on the surface or within the body; they are very difficult to detect without sophisticated inspection techniques. Porosity breaks the mechanical integrity of the casting and may result in leakage in pressure-containing components. Porosity type Description Origin Gas Porosity Smooth rounded voids Gas or air gets trapped Shrinkage Porosity Irregular cavities Inadequate feeding Micro Porosity Very fine void Rapid solidification Etiology and Prophylaxis The porosity may result from trapped air during injection, high turbulence in the molten metal flow, or poor die-cavity venting. Gas formation may also be due to high moisture content on die surfaces or due to inappropriate melt temperature. The porosity reduction is achieved by closely controlling injection speed and pressure, venting the dies, and efficiently utilizing vacuum systems where necessary. Maintaining an optimal melt temperature and keeping die surfaces clean and dry will also reduce gas entrapment. In most cases, reconstructing the gating system to facilitate smooth metal flow can go a long way toward minimizing porosity. Cold Shuts and Flow Line Defects Description and Impact Cold shut: This happens when two molten zinc streams meet and do not fuse correctly, leaving a visible seam or line on the casting surface. Such flaws reduce structural integrity and can cause early collapse under mechanical pressure. Root Causes and Solutions Low melt temperature, inadequate injection speed, or long flow paths can lead to premature solidification and cold shuts. Poor positioning of gates and thin wall sections also worsens the matter. To prevent cold shuts, it is necessary to improve the metal’s flow characteristics. These may be accomplished by raising the melt and die temperatures within reasonable ranges, optimizing injection velocity, and redesigning the gates to allow balanced filling. Flow continuity is also enhanced by changing part geometry to eradicate thin sections and acute angles. Zinc Die Casting Defects of Shrinkage Knowledge about Shrinkage Behavior When molten zinc solidifies, it contracts, causing shrinkage. Unless more molten metal is added to offset this contraction, internal cavities or surface sink marks can form. The zinc defects in the form of shrinkage usually arise in the areas of casting that are thick and can be ascertained to have solidified last. Reasons and Remedial Measures Insufficient holding pressure, inadequate feeding system design, or sudden changes in wall thickness are often the causes of shrinkage defects. Uneven cooling rates can also cause localized shrinkage. To prevent it, it is important to design the runners and gates to maintain a constant metal feed throughout the solidification process. By applying higher holding pressure and increasing the time under pressure, molten metal can compensate for shrinkage. Maintaining uniform wall thickness and enhancing thermal balance in the die also minimizes the risk of shrinkage-related defects. Flash Formation and Its Control Description of Flash Flash is in the form of thin layers of excess metal along the die parting line, ejector pin, or in the form of vents. Even though the flash does not necessarily compromise the part’s functionality, it often requires secondary trimming processes and can affect the appearance. Causes and Prevention Flash formation has often been linked to high injection pressure, die component wear, or even die misalignment. Die surfaces can also not seal properly due to foreign material on them. To avoid flash, it is necessary to maintain the correct amount of injection pressure, adequate clamping force, and routine die maintenance. Wearing and damage checking of dies, and

Zinc die casting is considered one of the preferred production processes for decorative hardware because it can produce complex, high-quality finishes at a cost-effective rate. This is done by forcing molten zinc alloy under high pressure into a precision steel mould to produce parts with superior surface finish, tight tolerances, and intricate geometries. Decorative hardware comprises door handles, cabinet knobs, pulls, hinges, scutcheons, and decorative accents for residential, commercial, and architectural applications. The low melting point (380-390 °C) and high fluidity of zinc allow for finely detailed thin walls (down to 0.5 mm), extended tool life (typically over 1 million shots), and large dimensions. These features make it suitable for decorative works that need to be both appealing and functional in the long term. Finishes such as chrome, nickel, brass imitation, or antique bronze enhance visual luxury and offer corrosion resistance. Ordinary Zinc Die Casting Decorative Hardware Alloys The choice of the right zinc alloy in the production of decorative hardware is critical to the performance, stability, appearance, and overall cost-effectiveness of the products. Zinc alloys are popular because they offer a good compromise between castability, strength, and finish. Alloy Composition Hardness Tensile strength (Mpa) Elongation % Applications Zamak 3 Zn 96% Al 4% Mg 0.03% 82   283   10   Doorknobs, escutcheons, ornamental plates Zamak 5 Zn 95% Al 4% Cu 1% 91   331   7   Cabinet pulls, hinges, locksets. Zamak 7 Zn 95.9% Al 4% Ni 0.02% 80   285   13   Intricate finials, decorative brackets ZA-8 Zn 91% Al 8.4% Cu 1% 103   372   6-10   Heavy-duty hardware like gate latches Zamak 3 The most common decorative hardware application is Zamak 3. It offers great castability, dimensional stability and a smooth as-cast surface. These characteristics make it suitable for door handles, cabinet knobs, rosettes, and other parts exposed to view. Zamak 3 also offers good compatibility with plating, painting, and powder coating, enabling manufacturers to achieve high-quality decorative finishes with minimal surface preparation. Zamak 5 Zamak 5 is enhanced with a small amount of copper, which enhances hardness and creep resistance. The alloy is typically used to make load-bearing decorative hardware, including hinges, locks, latches, and structural fittings. The increased mechanical strength enables the parts to withstand repeated stress and prolonged use, maintain good surface condition, and maintain good dimensions. Zamak 7 Zamak 7 is appreciated for its purity and fluidity. These features make it particularly appropriate for intricate, thin-walled, and ornate designs. It is frequently employed with complex hardware components that require sharp edges, fine finishes, and a high-quality surface appearance. ZA-8 ZA-8 has greater wear resistance and strength than standard Zamak alloys. Its application is commonly referred to as decorative hardware that is higher stress or mechanical load, and both durability and appearance are needed. Best Zinc Die Casting Products of Decorative Hardware Zinc die casting is critical in the manufacture of decorative hardware, as it provides a perfect blend of strength, accuracy, surface quality, and cost-effectiveness. Ornamental hardware accents are not merely useful; they also play a major role in the appearance of doors, furniture, and architectural interiors. Zinc die casting enables manufacturers to form complex shapes with tight tolerances and surface features, making it the choice for both high-end and mass-market decorative hardware. Zinc die-cast products, whether door handles and cabinet pulls, hinges, or ornamental accessories, are designed to withstand heavy use while retaining their beauty. Door Handles and Levers Decorative hardware products, such as zinc die-cast door handles and levers, are widely used for their flexibility in design, mechanical performance, and ergonomic comfort. These parts are typically designed with wall thicknesses of 1 to 2mm, making them very lightweight yet structurally sound. Draft angles of 1 to 2 degrees are commonly used to ensure easy ejection and maintain fine surface detailing. In fact, modern zinc die-cast lever designs are frequently designed with internal springs and mounting provisions. This integration reduces assembly complexity and enhances its smooth operation. These handles are made from high-quality zinc alloys to ensure tensile strengths up to 300 MPa and long-term resistance to bending and deformation. Well-designed zinc levers can withstand 500,000 or more cycles and are therefore used in entry doors, interior passages, and busy commercial settings. Cabinet Knobs and Pulls One of the most economical uses of zinc die casting is for cabinet knobs and pulls, as well as small, very delicate parts. Zinc also has great fluidity, which enables the manufacture of small designs with fine textures, impressed logos, and fine threading. Common cabinet knobs are about 1-1.5 inches in diameter, and common pulls have a 3-12-inch centre-to-centre spacing, all with high dimensional accuracy. Zinc die-cast cabinet hardware is so lightweight (typically 50-150 grams) that it is simple to install and use daily. The texture of the grips and the contour design promote comfortable handling, whereas the inner hardness of the zinc alloys provides resistance to scratches, fingerprints, and wear. Popular finishes include brushed antique brass, satin nickel, and oil-rubbed bronze, which are timeless and will fit both modern and antique furniture designs. Furniture and Door Hinges Hinges made by zinc die casting are appreciated for their smooth operation, consistent dimensions, and ability to incorporate functional features. The typical hinge types are hinges, concealed hinges, and pie-cut corner hinges. These hinges usually have loads of 20-50 kg, depending on the use. Zinc die casting enables the addition of self-lubricating properties, built-in stops, and accurate pivot points, thereby enabling smooth, quiet operation. Close dimensional tolerances of 0.05 mm ensure a tight fit between the doors and frames. Zinc hinges can be used in both the residential and light commercial markets, with nickel plating and other protective coatings providing up to 500 hours of corrosion protection. Keyhole Covers and Escutcheons Escutcheons and keyhole covers can be used to protect as well as be decorative. Zinc die casting allows making thin sections as small as 1 mm, while also enabling high-resolution details of 0.1 mm. Such accuracy enables manufacturers to create

Zinc die casting is a flexible production method which entails an injection of zinc alloy molten matter into a specially designed mold with high pressure in order to create complex and high-precision parts. Such an approach is especially appropriate for precision parts because zinc has high fluidity, a low melting point, and can be machined to tight tolerances without much post-processing. Zamak die casting is used in industries such as automotive, electronics, consumer goods, and medical devices for parts, including connectors, gears, housings, and complex mechanisms that require dimensional tolerances and longevity. Most zinc alloys are processed using hot-chamber machines, which enable quick cycle times and a steady quality. Accurate parts benefit from zinc’s ability to produce thin walls, complex geometries, and net-shape parts, reducing material waste and assembly time. Nevertheless, high success rates are achieved when specific design rules are followed, and material properties, shape, form, and processing parameters are considered. These rules help reduce defects, improve manufacturability, and enhance precision. This article identifies major guidelines supported by industry standards set by organizations to help engineers design zinc die-cast precision parts. Advantages of Zinc Die Casting of Precision Parts The use of zinc die casting offers several benefits, making it one of the best materials for precision applications. Selection Material: Zinc Alloys Selecting the correct zinc alloy is important for precision parts because it affects mechanical properties, castability, and tolerances. The Zamak die-casting series (2, 3, 5, 7) and the ZA series (8, 12, 27) have specific compositions and performance properties. The table below will summarize the kinds of zinc alloy used in the manufacture of precision parts: Types of Zinc Alloy Tensile strength (ksi/MPa) Elongation % Hardness (BHN)   Density g/cm³   Yield strength (MPa) Melting point °C Zamak 2 52/359 7 100 6.6 283 379-390 Zamak 3 41/283 10 82 6.6 269 381-387 Zamak 5 48/328 7 91 6.6 283-269 380-386 Zamak 7 41/283 13 80 6.6 310-331 381-387 ZA 8 54/372 6-10 100-106 6.3 359-379 375-404 ZA-12 59/400 4-7 95-105 6.03 145 377-432 ZA-27 62/426 2.0-3.5 116-122 5.3 N/A 372-484 These properties can be used to ensure that zinc alloys meet precision specifications and that complex parts have high fluidity scores (1-2 on a 1-4 scale; 1 best). To be more exact, manufacturers would want to choose alloys such as Zamak 3 or ZA-8 due to their stability and ability to withstand tight tolerances. Key Design Guidelines Good zinc die casting is designed to facilitate flow and ejection while maintaining strength at minimal cost. Wall Thickness The wall thickness should be uniform to avoid porosity and distortion. For precision parts, keep it within +/-10% and use a minimum thickness of 0.040 inches (1 mm) for a good surface finish, and as fine as 0.020 inches (0.5 mm) in miniature models. Ratios of thick to thin sections should be kept to less than 3:1 to minimize the chance of porosity; preferably the inscribed sphere diameter ratios should not exceed 6:1. Thickening walls enhances flow but raises the cycle time and consumption. To distances away from the ingate, minimum thickness changes: below 0.5 mm in areas less than 50 mm, up to 2 mm at 200 mm. Different simulations can be used to check designs. In zinc casting, specify a minimum of 0.025 inches (0.635 mm) in selected locations, but 0.040 inches (1.016 mm) in best-as-cast locations. Draft Angles Draft angles help eject parts and prevent damage to the die. For zinc, the minimum drafts are 0.5 ° -1 on outside surfaces, 1- -1 on internal surfaces, and 0.1 ° -1 on round holes. Short features that use moving parts (die elements) can be printed in zero, but it is more expensive. For ribs, a 5-10 taper is used when it is not parallel to the shrinkage. Different standards give draft calculations: standard tolerances are 50 (draft angle approximately 1.9 degrees at a 1-inch depth) for inside walls and 100 for outside walls. There are also precision tolerances that permit 60 and 120 constant drafts. Fillets and Radii Fillets and radii should always be added since sharp edges lead to stress concentrations and die erosion. Minimum radius of inside fillet is 0.016 inches (0.4 mm), and outside 0.031 inches (0.8 mm). Radii of larger size (up to 0.063 inches or 1.6 mm) enhance flow and strength. Minimum radii should be used (0.060 inches (1.5 mm) for bosses and ribs). Radius at high stress should not be less than 1 mm; standards suggest ±0.08/±0.04 inches (±2/±1 mm) in fillets. This improves the part’s life and reduces cracking. Ribs and Bosses Ribs enhance reinforcement without adding bulk. Create shallow, rounded ribs (height-to-thickness ratio no more than 3:1) and evenly space them so they are not distorted. Adhesion ribs to walls with fillets to avoid porosity in the intersection. The height of bosses used to mount or thread must be equal to their diameter, and when the diameter is large, they must have ribs. Keep 0.25 inches (6.5 mm) distance between bosses. Tolerances of critical heights can be contained in ribs, such as in the precision designs of ±0.001 inches (±0.025 mm) ribs. Cored Holes and Threads Holes made in the core make it lighter and allow elements such as threads. Maximum depths are around 3 mm diameter, 9 mm blind or 24 mm through; up to 12 mm diameter with larger openings. At least 0.25 inches (6 mm) in diameter, L/D ratio not more than 4:1 in small holes. Parting Line Considerations It is best to place the parting line in the largest section possible to produce the least amount of flash and to allow easy trimming. Vertical or complicated lines should be avoided; die motion plane right angles are best. Tolerances on parting lines are the sum of linear ones, by projected area. Projected area Tolerance (+in) Upto 10 +0.0045 11-20 +0.005 21-50 +0.006 51-100 +0.009 Tolerances of Precision Parts Zinc die casting has even higher precision tolerances than standard, and sometimes 65% of those special controls are

Basınçlı döküm, imalat sektöründe yüksek hassasiyetli metal ürünler üretmek için de uygun ve çok yönlü bir süreç olmuştur. Alüminyum ve çinko en yaygın basınçlı döküm alaşımları arasındadır. Bir ürünün üretimi, mühendisliği veya malzemelerin bulunması ile uğraştığınızı varsayarsak, çinko basınçlı döküm ile alüminyum basınçlı döküm arasındaki farkı anlamanız gerekir. Bu kılavuz, ister otomotiv parçaları, ister elektronik veya tüketim malları olsun, üreticilerin projeleri için en uygun alaşımı seçmelerine yardımcı olacaktır. Basınçlı döküm, yüksek yüzey kalitesine sahip karmaşık şekiller üretmek için sıcak erimiş metalin yüksek basınç altında bir kalıba dökülmesi işlemidir. Hem çinko hem de alüminyum dökümün kendi avantajları ve dezavantajları vardır. Ayrıca, bilinçli bir karar vermenize yardımcı olmak için derinlemesine karşılaştırmalar, tablo halinde, hızlı izlenen bir görünüm ve profesyonel yorumlar sunacağız. Sonunda, çinko basınçlı döküm ve alüminyum basınçlı döküm arasındaki farkı ve bunlardan herhangi birini ne zaman kullanacağınızı açıkça anlayacaksınız. Şimdi temel faktörleri inceleyelim. Basınçlı Döküm Nedir? Hızlı Bir Bakış Çinko basınçlı döküm ve alüminyum basınçlı dökümü karşılaştırmadan önce basınçlı döküm sürecini anlamak çok önemlidir. Basınçlı döküm, erimiş metalin yüksek basınç altında (1.000 ila 20.000 psi) bir kalıp boşluğuna zorlanması işlemidir. Sertleştirilmiş çelik kalıp veya kalıp tipik olarak sıkı toleranslara sahip binlerce benzer parça üretebilir. Basınçlı Döküm Çeşitleri Sıcak Kamara Basınçlı Döküm Çinko gibi düşük erime noktalı metallerde uygulanır. Enjeksiyon sistemi erimiş metale daldırılır. Soğuk Kamara Basınçlı Döküm Metalin alüminyum gibi daha yüksek bir erime sıcaklığına sahip olduğu durumlarda en iyisidir. Erimiş metalin hazneye yüklenmesi makineye zarar vermesini önlemek için yapılır. Hızı, doğruluğu ve kapsamlı işlem sonrası olmadan karmaşık tasarımlar oluşturma yeteneği nedeniyle tercih edilir. Bu noktada, iki yıldız alaşımı karşılaştıracağız: çinko ve alüminyum. Çinko ve Alüminyum Basınçlı Dökümün Birincil Özellikleri Çinko ve alüminyum basınçlı döküm arasındaki karar genellikle malzeme özelliklerine indirgenir. Çinko (ve genellikle Zamak olarak alaşımlandırılır) ve alüminyum (ADC12 veya A380 gibi) aynı mukavemetleri, ağırlığı, korozyon direncini vb. paylaşmaz. Mukavemet ve Dayanıklılık Çinko alaşımlarının büyük darbe mukavemetine ve sünekliğe sahip olduğu bildirilmiştir. Kırılmadan önemli gerilime dayanabilirler, bu da onları dökümden sonra bükülmesi veya şekillendirilmesi gereken bileşenler için uygun hale getirir. Öte yandan alüminyum alaşımları, özellikle yapılarda çekme mukavemeti ve sertlik açısından üstündür. Ağırlık ve Yoğunluk Yoğunluğu 6,6 g/cm 3 olan çinko ile karşılaştırıldığında alüminyum daha hafiftir (d = 2,7 g/cm 3). Bu, alüminyumun havacılık ve uzay endüstrisi gibi düşük ağırlık gerektiren endüstrilerde kullanılmasına katkıda bulunur. Erime Noktası ve Dökülebilirlik Çinko yaklaşık 380-390 °C'de eriyerek sıcak hazneli makinelerin daha hızlı çalışmasını sağlar. Yalnızca alüminyum 660 °C'de erir, bu da üretimi yavaşlatabilecek ancak daha ince duvarlara olanak tanıyan soğuk hazne işlemleri anlamına gelir. Korozyon Direnci Her ikisi de iyi bir dirence sahiptir; ancak alüminyum doğal olarak koruyucu bir oksit kaplama oluşturduğu için zorlu koşullar altında daha iyi performans gösterir. Çinkonun dış mekan kullanımı kaplama gerektirir. Özellikler Çinko basınçlı döküm Alüminyum basınçlı döküm Erime noktası 380-390 derece 660 derece Çekme mukavemeti 280-400 200-300 Yoğunluk 6,6 2,7 Termal iletkenlik 109 100-140 Elektrik iletkenliği Yüksek Çok yüksek Darbe mukavemeti Sünek Kırılgan Korozyon direnci İyi Çinko Basınçlı Dökümün En İyi Faydaları Çinko basınçlı dökümün çok yönlülüğü, onu yüz yıldan fazla bir süredir güvenilir bir seçenek haline getirmiştir. Bu yüzden üreticiler onu çok sevmektedir: Olağanüstü Boyutsal Doğruluk Çinko, 0,05 mm veya daha azına kadar bozulmadan kalır ve ikincil işleme ihtiyacını ortadan kaldırır. Üretici, çinko basınçlı döküm kalıpları ile aşırı boyutsal doğruluk elde edebilir. Yüksek Yüzey Hammaddenin kendisi yüksek kaliteli bir yüzeye sahiptir. Parçalar temiz çıkar ve genellikle kaplanmadan veya boyanmadan önce ek parlatma gerektirmez. Uzun Takım Ömrü Çinko kolayca erir, bu nedenle kalıplar daha az aşınır, bu da daha düşük uzun vadeli takım maliyetleri ile sonuçlanır. Ürünler korozyona ve aşınmaya dayanıklıdır, bu da daha uzun bir kullanım ömrü sağlar. Hızlı Üretim Hızı Erimiş malzeme 15-30 saniye içinde katılaşır. Bu da çinko basınçlı dökümü yüksek hacimli üretim için uygun hale getirir. Büyük ölçekli endüstri, üretimi iyileştirmek ve artırmak için kullanır. Küçük Parçalar İçin Uygun Fiyatlı Çinko, kilitler, dişliler ve donanım gibi karmaşık, küçük parçalar için idealdir. Ancak ağırlığa duyarlı uygulamalar, daha yüksek yoğunluğu nedeniyle çinkoyu daha az tercih edilebilir hale getirebilir. Standart alaşımlara örnek olarak Zamak 3 (genel amaçlı) ve Zamak 5 (daha yüksek mukavemetli) verilebilir. Uygulamalar Otomotiv sektörü gibi diğer sektörlerde çinko, kapı kolları ve braketlerde kullanılır. Elektronik söz konusu olduğunda, EMI'ye karşı kalkan oluşturabildiği için bağlantılarda tercih edilir. Alüminyum Basınçlı Dökümün Faydaları Daha büyük ve yapısal bileşenlerde alüminyum basınçlı döküm önde gelir. Faydaları şunları içerir: Hafif ve Güçlü Alüminyum bileşenler, ürünün toplam ağırlığını çelik veya çinkoya kıyasla yüzde 50 oranında azaltabilir. Alüminyum hafif ama güçlüdür. Bu da alüminyum dökümün yüksek mukavemetli uygulamalara uygun ürünler üretmek için ideal olmasını sağlar. Mükemmel Korozyon Direnci Çoğu durumda daha fazla kaplamaya ihtiyaç duymaz, bu da zaman ve para tasarrufu sağlar. Alüminyum dökümden yapılan ürünler daha uzun ömürlüdür ve bozulmadan kalır. İyi Termal ve Elektriksel İletkenlik Alüminyumun elektrik ve ısı iletme yeteneği, onu çok çeşitli uygulamalar için ideal kılar. Isı alıcılarında, motor bloklarında ve elektrik muhafazalarında kullanım için mükemmeldir. Geri Dönüştürülebilirlik Alüminyum kalıp döküm prosesi, sürdürülebilir üretim trendlerine uygun olarak yüksek geri dönüştürülebilirliği - yüzde 100 alüminyum geri dönüşümü - nedeniyle en iyisidir. İnce Duvar Kabiliyeti Alüminyum basınçlı döküm 0,5 mm'ye kadar ince duvarlar üretebilir ve karmaşık tasarımlara olanak tanır.

Introduction In the automotive industry, zinc has been a pillar raw material for die casting because it has a remarkable mixture of precision, strength, durability and cost-effectiveness. Automakers are also turning to the use of zinc alloys in those parts that demand tight tolerances, thin walls, high surface finishes, wear and corrosion resistance. This is used in common applications such as door handles, lock housings, seat belt mechanisms, gears, brackets, sensor housings and inner trim pieces. The technology is to inject high-pressure molten zinc into steel moulds, which can be of complex geometry and volumes with limited secondary machining. Chinese Mold Manufacturer has already dominated the world of zinc die casting by being able to offer tailor-made prices, facilities and the necessary certification, such as the IATF 16949, that is required by automobile suppliers. This paper summarizes the top zinc die casting service companies focusing on automotive parts, based on the capabilities of the companies, customer reviews and industry reputation. We are targeting the Chinese manufacturers, who are the major source of worldwide provision of low-priced yet high-quality motor parts. Key Advantages of Zinc Die Casting With the latest development of vehicles towards electrification and lightweighting, zinc die casting services are important to making dependable, high-performance components. The Zinc Die Casting Process Zinc die casting is a very efficient production process that is accurate in making complex metal parts that have superior surface finishes. It is especially well used in the auto industry with parts that have thin wall requirements, are high strength and have better plating compatibility. Just like aluminum die casting, zinc employs the hot-chamber process because it melts at a lower temperature (approximately 420 °C), providing it with short cycle times and extended tool life. Principles of the Zinc Die Casting Process Mold Preparation To ease ejection and temperature control, the steel die (mold) is sprayed with lubricant. The mold is made from strengthen material like steel that contains all the details of the automotive parts. Melting and Injection Zinc alloy (usually Zamak 3, 5 or ZA-8) is melted in a furnace that is connected to the machine. A gooseneck plunger is inserted into the molten metal and forces the final under high pressure (as much as 30 MPa) into the die cavity. Solidification The metal solidifies (a few seconds) in the water-cooled die, and the metal is solidified in its form of choice. Ejection The die is cast, and ejector pins push out the casting. The final shape of the product is solidified. Trimming and Finishing Flash (runners) is removed. The secondary processes, such as machining, plating or powder coating, are included. Trimming the unwanted part of the zinc automotive product is the final step. Why Zinc Die Casting is Superior in Automotive Applications Zinc alloys (i.e., Zamak 3, 5, and ZA-8) have distinct advantages compared to such alternatives as aluminum: High Quality Finish and Surface Finish Zinc fluidity allows adding thinner walls (down to 0.5mm) and finer details to minimize the post-processing. The automotive parts made from zinc have thinner walls and greater strength. Increased Strength and Impact Resistance Suited to components with safety-critical functions such as seat belt retractors and locks. The automakers preferred using these products. Extended Tool Life Due to the low melting point, zinc die casting products’ life is increased, and high-volume runs have reduced costs. Outstanding Plating Compatibility The process of zinc die casting is ideal for exterior or interior parts, as these are chrome-plated. Economical with Medium Volumes The automotive parts made by zinc diecasting use hot-chamber processes and have faster cycle times than aluminum. Zinc vs. Aluminum Die Casting Comparison for Automotive Parts Automotive parts could be made from zinc or aluminum. Here is the comparison table for the users to make the best decision according to their need of product. Features Zinc die casting Aluminum die casting Wall thickness Thinner (0.5-1.5mm) Thicker (2-5mm) Weight Higher High Melting point Low High Thermal conductivity High Low Corrosion resistance Higher Low Impact/strength High impact resistance Greater ductility Tool life Longer Shorter Cost Better for smaller parts Better for larger parts Applications Auto marine Power steering system Fuel system Engine system Automotive components Aerospace House appliances Medical automotive Best Die Casting Providers of Zinc                                                                                      Die Castings China (CNM Tech) This is a company that deals with zinc die casting and aluminum in the automotive parts industry in Dongguan, which is a die-casting hub.

Çinko basınçlı döküm, hız, doğruluk, mukavemet ve ekonomikliğin gerçekten önemli olduğu endüstrilerde yaygın olarak uygulanan bir üretim yöntemidir. Çinko alaşımları, yüksek döküm özellikleri, boyutsal kontrol, mukavemet ve çok yönlülükleri nedeniyle otomotiv, havacılık, tüketici elektroniği uygulamaları ve daha birçok alanda kullanılmaktadır. Pürüzsüz yüzeylere sahip karmaşık şekiller yapmak için kullanılabilirler ve bu da seri üretimde kullanılmalarını oldukça talep edilir hale getirir. Çıplak çinko yüzeyler olumsuz ortamlara maruz kaldıklarında kolayca aşınır, kararır ve genellikle yıpranır, bu da koruyucu bir son kat uygulama ihtiyacını doğurur. İşte bu noktada kaplama, hem ürünlerin kullanılabilirliği ve kullanım ömrü hem de ürünlerin pazardaki çekiciliği ve profesyonel görünümü açısından en önemli adımlardan biri haline gelmektedir. Yüzey bitirme gibi konular ele alındığında, çinko döküm parçaların kaplanması eskiyen ortamlara karşı daha fazla direnç, görünüm ve dayanıklılığı garanti eder. Dünya genelinde imalat endüstrisinde en yaygın süreçler krom kaplama, çinko döküm ve çinko döküm üzerine nikel kaplamadır. Kaplama, kullanım ömrünün yanı sıra ticari değer de yaratır çünkü müşteriler her zaman güçlü ancak parlak, yüksek kaliteli bir yüzeye sahip ürünler ister. Bu da kaplamayı mevcut endüstrilerde temel bir faaliyet haline getirmektedir. Bu makalede, kaplamanın neden gerekli olduğuna, teknik sürecin nasıl işlediğine, zorluklara ve sürece bağlı endüstriyel faydalara ilişkin argümanların ayrıntılı bir özetini vereceğim. Çinko Kaplama Basınçlı Döküm Nedir? Çinko basınçlı döküm, çinko basınçlı döküm kullanılarak dökülen bileşenlerin üzerine koruyucu ve dekoratif bir metal kaplamanın eşit şekilde kaplanması için kullanılan bir işlemdir. Çinko alaşımlarının güçlü ve uygun maliyetli, ancak aşındırıcı ve aşınmaya bağımlı olduğu göz önüne alındığında, kaplama dayanıklılığı, görünümü ve çalışmayı uzatır. Basitçe söylemek gerekirse, çinko basınçlı döküm gerçek parçayı veya bileşeni üreten süreçtir, kaplama ise yüzeye koruyucu bir kaplama yerleştiren ve gerekli son işlemi sağlayan ekstra bir katman uygular. Kaplama ve kaplama çinko döküm ürünleri, krom kaplama çinko döküm yoluyla bir ayna kaplaması veya nikel kaplama, çinko döküm yoluyla koruyucu, üst düzey bir kaplama elde etmek için. Bu bileşim, kaplamalı çinko dökümün, iyi görünüm ve mukavemetin potansiyel gereklilikler olduğu otomotiv döşeme, elektronik muhafazalar, ev ve endüstriyel ekipmanlarda geniş bir uygulama yelpazesi bulmasına yol açar. Kaplama nedir? Kaplama, elektrokaplama (elektrik akımı kullanımı) veya kimyasal kaplama (elektrik akımı kullanılmadan) yoluyla başka bir malzemenin yüzeyine ince bir metal tabakasının eklenmesidir. Kaplama, alt tabakanın estetiğini, aşınma direncini, korozyon direncini, iletkenliğini ve aşınma direncini artırmak için yapılır. Çinko döküm parçalar üzerinde nikel veya krom kullanarak, mukavemet ve şekil sağlayan temel çinkoya koruma ve parlaklık katmamız buna bir örnektir. Bir arabanın parlak krom tutamağı veya bir banyo özelliğinin parlak yüzeyi, kaplamanın doğrudan bir sonucudur. Kısacası kaplama, bir ürünün daha kalıcı ve çekici görünmesini sağlamak için ona bir kalkan ve güzel bir yüzey sağlamaya benzer bir işlemdir. Çinko Basınçlı Dökümün Kaplamaya İhtiyaç Duymasının Nedeni Çeşitli uygulamalarda kullanılabilen çinko alaşımlarının güçlü yanlarına rağmen, ham olduklarında bazı sınırlamalar vardır. Kaplanmamış çinko, nem, kimyasallar ve termal değişim nedeniyle kararma veya korozif saldırıya maruz kalır. Düz, kaplanmamış parça birçok endüstride uzun vadeli güvenilirlik için yeterli değildir. Kaplama yoluyla yapılan yüzey işlemleri sadece kozmetik amaca hizmet etmekle kalmaz, aynı zamanda mühendislikte de çeşitli avantajlar sağlar. Üreticiler kaplama çinko döküm tekniklerini kullanarak korozyon, aşınma ve oksidasyona karşı önlemlerini artırmaktadır. Bu, uzun vadede ürünün hem yapısının bütünlüğü hem de estetik çekiciliği açısından dayanıklılığını garanti eder. Ayrıca, tüketici ürün bileşenlerine en uygun yüksek parlaklıkta bir yüzey sağlayan krom kaplama, çinko döküm ve hem koruyucu hem de dekoratif bir kaplama olan çinko döküm üzerine nikel kaplama gibi özel kaplamalar da mümkündür. Çinko Basınçlı Dökümler Üzerine Kaplama İşlemi Kaplama, hassas bir hazırlık ve uygulama gerektiren karmaşık bir süreçtir. Alüminyum ve çelikten farklı olarak çinko alaşımları, çinkonun reaktivitesi nedeniyle alışılmadık zorluklar ortaya çıkarır. Bu nedenle, çinko üzerine kaplama, iyi bir yapışmayı garanti etmek için özel bir işlem gerektirir. Yüzey Hazırlama 1: Yüzey Hazırlama İlk işlem, yağın, yağlayıcının ve yabancı maddelerin dökümden uzaklaştırıldığı yağ alma işlemidir. Sıkı bir temizlik yapılmazsa, soyulma veya pullanma meydana gelir, bu da çinko döküm parçaların kullanımında zayıf bir yapışma anlamına gelir. Adım 2: Seçme Dökümler aside daldırılarak deoksidize edilir ve temizlenir. Bu, yüzeyi temiz, aktif ve kaplama katmanlarını kabul edebilecek hale getirir. 3. Adım: Vuruş Katmanı Uygulama Çinko alaşımları çok reaktiftir; bu nedenle, son işlemden önce yapışmayı artırmak için normalde ince bir bakır veya nikel vuruş katmanı kullanılır. Bu, hem krom kaplama, çinko basınçlı döküm hem de çinko basınçlı döküm üzerine nikel kaplama için çok önemli bir adımdır. Adım 4, son kaplama katmanı Dirençli olmayan metaller, krom, nikel veya diğer alaşımlar yüzeyi kaplamak için elektrolizle kaplanır. Bitmiş ürünün dayanıklılığı ve görünümü bu katmana, kalınlığına ve kalitesine bağlıdır. Çinko Basınçlı Dökümlerin Krom Kaplaması Çinko basınçlı dökümlere uygulanan en beğenilen bitirme tekniği krom kaplama olarak adlandırılır; bu bitirme türü çinko parçanın dayanıklılığını, işlevselliğini ve güzelliğini artırmak için kullanılır. Krom kaplama, elektrokaplama işlemi yoluyla çinko döküm nesnelerin yüzeyine çok ince bir krom metal filminin yapıştırılmasını ifade eder. Sonuçta ortaya çıkan parlak, ayna benzeri kaplama, nesnenin estetiğini artırırken aynı zamanda parçayı korozyona, çizilmelere ve günlük aşınmaya karşı güçlendirir. Krom kaplama objelerin, daha zor koşullarda çabuk kararma eğilimi olan ham çinko yüzeyi koruyacağı ve ürünlerin dayanıklı olduğu tespit edilmiştir. Önemli Avantajları

Basınçlı Döküm Nedir? Basınçlı döküm, erimiş metalin kalıp boşluğuna preslenmesiyle karakterize edilen bir metal döküm işlemidir. Kalıp boşluğu, işleme sırasında üzerinde çalışılan ve enjeksiyon kalıplarına benzer şekilde çalışan iki sertleştirilmiş takım çeliği kalıbı kullanılarak yapılır. Çoğu kalıp döküm, demir dışı metallerden, özellikle çinko, bakır, alüminyum, magnezyum, kalay, kurşun ve kalay bazlı alaşımlardan yapılır. Atılan metalin türüne bağlı olarak, termal veya soğuk bir motor kullanılır. Çinko basınçlı döküm işlemi, inşaat ve endüstriyel alanlarda parça yapımında çok popülerdir, ancak en yaygın uygulama otomotiv endüstrisindedir. Aslında, otomobillerin basınçlı döküm yoluyla yapılabilecek farklı parçaları vardır, öyle ki modern basınçlı döküm süreci başlangıçta otomotiv endüstrisi için başlatılmıştır. Döküm işlemi ile genellikle dökümden sonra başka bir işleme gerek yoktur: sadece 99.8%'ye kadar doğruluk değil, aynı zamanda dökülen ürünler hoş bir yüzeye sahip oldukları için ham olarak da kullanılabilir. Çinko basınçlı dökümün kullanımı otomotiv endüstrisinde neredeyse 28%'dir ve bunu yapı ve donanım sektörü izlemektedir. Çinko, özellikle emniyet kemeri sistemlerindeki kapı kilidi muhafazası, mandal, dişliler ve retraktör kasnakları gibi ürünlerin yanı sıra eksantrik mili ve sensör bileşenleri için de otomobil parçaları endüstrisindeki en önemli metallerden biri haline gelmiştir. Bu metal ve alaşımları kullanılarak, diğer malzemelerle mümkün olmayacak mukavemet, süneklik ve esneklik elde etmek mümkündür. Ayrıca çinko, diğer malzemelerle mümkün olmayan sıkı toleranslara sahip yüksek kaliteli estetik bileşenler elde etmek ve mekanik bileşenler veya dişliler için kabartma ve oluklar elde etmek için doğru seçim olabilir. Otomotivde Çinko Basınçlı Döküm Mekanizmaları Daha önce de belirtildiği gibi, otomotiv endüstrisi en yaygın basınçlı döküm uygulamasıdır: çinko ve alaşımlarının kullanılması, şekil morfolojisi için sıkı ve dar toleranslarla yüksek estetik kaliteye ulaşabilen bileşenlerin üretilmesini mümkün kılar. Çinko alaşımları, çinkonun zaten etkileyici olan korozyon önleyici özelliklerini geliştirmek gibi birçok faydası nedeniyle kaplamalar için de kullanılır. Aşağıda bir dizi olası çinko kaplama örneği bulabilirsiniz: İç estetik bölümü Sunrooflar Bölümü Mekanik parçalar Motor ve diğer kaporta altı bileşenleri Hidrolik direksiyon sistemi Parçaları ve fren sistemi Klima bileşenleri ve sistemleri Şasi donanımı Emniyet kemeri sistemindeki parçalar Klima kontrolü bileşenleri Yakıt sistemi Çinko Basınçlı Döküm için Avantajlar: Çeşitli form ve biçimleri mümkün kılan verimli ve ekonomik bir süreç. Yüksek Hızlı Üretim Boyut Doğruluğu ve İstikrar Mukavemet ve ağırlık Çeşitli sonlandırma teknikleri mevcuttur Basit Montaj Basınçlı Döküm süreci kurşun ve kurşun alaşımlarının kullanımıyla başlamış, bunu hızla magnezyum ve bakır alaşımları izlemiş ve 1930'larda, bugün hala kullanılan birçok modern alaşım mevcuttur. Bu süreç, düşük basınçlı enjeksiyon dökümünden inç kare başına 4.500 poundluk modern yüksek basınçlı enjeksiyona doğru evrilmiştir. Modern süreç, mükemmel yüzey kaplamalarına sahip yüksek bütünlüklü, temiz döküm formları üretebilmektedir. Çinko döküm alaşımı güçlü, dayanıklı ve uygun maliyetli bir mühendislik malzemesidir. Mekanik özellikleri rekabetçidir ve genellikle dökme alüminyum, magnezyum, bronz, plastik ve çoğu dökme demirden daha yüksektir.
