Hliníkové tlakové odlitky mají pozoruhodné využití v různých průmyslových odvětvích, zejména v leteckém a kosmickém průmyslu, kde má největší význam přesnost a špičkový standard. Tyto předměty se používají při výrobě malých i velkých součástí v leteckém průmyslu. Kromě toho se hliníkové odlitky pod tlakem používají jak v klíčovém vojenském, tak i v komerčním sektoru. Důvod je jednoduchý - jsou to cenově výhodná řešení a poskytují úžasné výsledky. Kromě nákladového efektu jsou díly vyrobené z tlakového lití hliníku navíc připraveny odolávat extrémním povětrnostním podmínkám a zvýšenému poškození. Dalším zásadním důvodem pro použití hliníkových výrobků v letadlech je to, že mouka je relativně cenově dostupná než jiné kovy, které se odlévají pod tlakem. Další, hliník má potenciál dostat se s jinými kovy, aby poskytl trvanlivost a mnohem flexibilnější. S hliníkovými odlitky nemusíte dělat kompromisy ohledně standardu, přesto je můžete vyrábět za mnohem přijatelnější výrobní náklady. Dále, všechny normy, které byly stanoveny pro použití kovových součástí, hliník uvolnit potřebu na maximum. Proto jsou certifikované bezpečné pro použití v letadlech, cenově dostupné a mají všechny vlastnosti, které jsou potřebné pro létající plavidla. Odlévání hliníku je tedy na vzestupu jako nikdy předtím. Dále je špičkovou vlastností hliníkového tlakového odlitku to, že jeho hmotnost je příznivá pro práce v letadle. Jak se tedy vlastně odlévání hliníku provádí a jaké jsou s tím spojené procesy? Odpověď je jednoduchá. Hliníková slitina se nejprve vtlačí do špičkové oceli vysokou rychlostí a silou při vysoké teplotě. Výsledkem jsou nadstandardní výrobky, které jsou velmi lehké a tenkostěnné, ideální pro použití jako součásti letadel. Je třeba zmínit, že lití hliníku je náročná technika. Pouze skutečně zkušený a špičkový tým inženýrů může zajistit, že díly budou mít špičkové objemy nebo vynikající tolerance a povrchovou úpravu. Ve skutečnosti je tento typ silového lití mnohem známější než gravitační tlakové lití nebo lití do písku. Je to proto, že potřeba obrábění je u tohoto typu počasí pro zinkové nebo hliníkové odlitky extrémně nízká vzhledem k těsným tolerancím odlitků. Přestože náklady na nástroje při odlévání hliníku nebo spíše jakéhokoli kovu jsou podstatně vyšší než u ostatních dvou typů, mechanické vlastnosti, kterých se takto dosáhne, jsou z hlediska funkčnosti mnohem lepší.

Die Casting clamping force is the force applied to a mold by clamping unit of HPDC die casting machine. The clamping force must be grater their separating force. Which applied by the injection of molten metal into the mold The clamping fore > separating force How to calculate the separating force (opening force)? Opening force is the force acting on the cavity to make the die expand during the production of die casting part. The opening force can be calculated by the following formula: F=PXA F: opening force P: specific injection pressure A: Total projected area What is Specific injection pressure? Molten metal is ladled through the shot hole into the cold chamber and the shot plunger pushes the metal into the die. The pressure applied by plunger to push the metal into the die is specific injection pressure. Injection pressure use for different type of casting: For standard casting =600 kg/cm2 For technical casting =600−800 kg/cm2 For pressure testing casting =800 kg/cm2 What is projected area? The anticipated region is a two-dimensional zone estimation of a three-dimensional article by anticipating its shape on the plane. Total projected area =casting projected area + slide projected area + runner projected area + overflow projected area Example Casting projected areas =56000mm2 Overflow + runner projected area =22400mm2 (40% of total casting projected area ) Slide projected area=projected area must be selected in the plane that is normal to be direction of core travel x tanꬾ Angle of wedge = angle of finger cam angle + 2degree Force FY = F X Tan ꬾ ꬾ = angle of wedge lock Example: Slide core 1 projected area=area normal to direction of travel × tanꬾ =5000× tan20 degree =5000× 0.36 =1800 m2 Slide core 2 projected area=4500×tan 20degree= 1620mm2 so, Total projected area= 56000+22400+1800+1620mm2                                                                        =81820 mm2 What is separating force (Opening force)? (For technical casting=600−800 kg/cm2) (800 kg/cm2       =8kg/mm2) Opening force = specific pressure ×total projected area =8 kg/mm2 × 81820mm2 =654560 kg/mm2 (1 ton = 1000kg) =654.56 T Die clamping force The clamping force must be grater then the separating force. Locking force require =F×1.2 =654.56×1.2 =785.472 tons We select the 900T machine What is fill ratio, how it is important for selecting machine tonnage? It is the percent of liquid metal vulnerable chamber contrasted with the absolute volume of the virus chamber. Another method for saying it would be the level of metal contrasted with the level of air exposed to the harsh elements chamber For Example 50% full (of metal) = 50% air remaining The level of fill is significant in light of the fact that it is utilized to ascertain the ideal moderate shot speed. This can have a quality impact on the casting. Fill ratio (30-40%) is good for automobile die casting component quality.

What is Die Casting? Die casting is a metal casting process which is characterized by pressing molten metal into the mold cavity. The mold cavity is made using two hardened tool steel molds that are worked on during processing and work similarly to injection molds. Most die-casting is made from non-ferrous metals, especially zinc, copper, aluminum, magnesium, tin, lead, and tin-based alloys. Depending on the type of metal being thrown, a thermal or cold engine is used. The zinc die casting process is very popular for making parts in building and industrial fields, but the most common application is in the automotive industry. In fact, cars have different parts that can be made through die casting, in such a way that the modern process of die casting was originally started for the automotive industry. With the casting process often no further machining is needed after casting: not only is the accuracy up to 99.8%, but the casted products can also be used raw because they have a pleasant finish. The use of zinc die casting is almost 28% in the automotive industry, followed by the building and hardware sector. Zinc has become one of the most important metals in the auto parts industry, especially for products such as door lock housing, pawl, gears and retractor pulleys in seat belt systems, but also for camshaft and sensor components. By using this metal and its alloys, it is possible to achieve strength, ductility, and flexibility that would not be possible with other materials. In addition, zinc can be the right choice to get high-quality aesthetic components, with tight tolerances that are not possible with other materials, and to get embossing and grooves for mechanical components or gears. Zinc Die Casting Mechanisms in Automotive As said before, the automotive industry is the most common die casting application: using zinc and its alloys makes it possible to produce components that are able to achieve high aesthetic quality, with tight and narrow tolerance for shape morphology. Zinc alloys are also used for coatings because of its many benefits, such as improving the anti-corrosion properties of zinc which are already impressive. Below you can find a number of possible examples of zinc plating: Interior aesthetic section Sunroofs Section Mechanical parts Engine and other underhood components Power steering system Parts and brake system Air conditioning components and systems Chassis hardware Parts in the seat belt system Components of climate control Fuel system Advantages for Zinc Die Casting: An efficient & economical process offering various forms & forms possible. High-Speed ​​Production Dimension Accuracy & Stability Strength & weight Several finishing techniques are available Simple Assembly The Die Casting process began with the use of lead and lead alloys, magnesium and copper alloys which were quickly followed, and in the 1930s, many modern alloys still in use today are available. This process evolved from casting low-pressure injection to modern high-pressure injection of 4,500 pounds per square inch. The modern process is capable of producing high integrity, clean casting forms with excellent surface finishes. Zinc casting alloy is a strong, durable and cost-effective engineering material. Their mechanical properties are competitive and are usually higher than cast aluminum, magnesium, bronze, plastic and most cast iron.

The climbing phase: The 1st step is to prepare the die halves for casting by cleaning the faces of each die then applying lubrication or release agent. Once the die has been prepared, the die halves are closed and clamped together with pressure applied from the die-cast machine. The clamping force will depend upon the size of the machine but must be more than the opposing force trying to open the die during the casting process. The injection phase: The ingots are added to the furnace and kept molten at a set temperature according to the metal being used. The molten metal is transferred to an injection chamber and injected into the closed die pressure ranging from 1000 to 20,000 psi. The pressure is maintained while the metal solidifies. The amount is injected into the die is known as the ‘shot’ The injection of metal into the die is very short, this ensures the metals do not start to solidify before the die is completely filled. The cooling phase: After the injection is complete, the molten metal needs to solidify before the die is opened. The cooling time will depend upon the part geometry as well as the metal thermodynamic properties. The wall thickness of the parts plays a big factor in the cooling time, the thicker the wall section the longer the cooling time required. The ejection phase: After the cooling time has elapsed, the two die halves can be opened. An ejection mechanism then pushes the solidified casting out of the die. The force of the ejection will be determined by the size of the part, bearing in mind, the part shrink during the cooling process and tends to stick to the die surface. Once the part has been ejected, the die can be closed ready for the next injection cycle. The trimming phase During the cooling and solidification phase, the casting will solidify as a complete cast unit which includes the part, flash, and any runner system This excess material must be trimmed off to leave just the main cast product. Method of trimming includes trim tools, band saw are manually clipping. Any trimmed metal is either scrapped or recycled if permitted. Advantages of die casting: Die casting is fast Die casting can be produced in seconds each part and quantities of hundreds to thousands of metal parts each day. Near net shape Die casting are produced “near net shapes” no matter how complex the shape are how tight the tolerances are. Lighter weights Die casting are stronger because of the material surface skin not the thickness of materials so parts can weigh less with thinner casting wall thicknesses. Die casting is versatile Many more part shapes and sizes can be produced using the die casting manufacturing process. Die casting are durable Die castings parts are metal and have a long service life. Die castings are inexpensive Die castings are fast to produce and useless material. Die casting are typically less expensive than most other metal parts manufacturing processes.

The process of die casting with pressure injection can be followed until mid-1800. The components used were tin and lead, but the use has disappeared with the introduction of zinc and Aluminium alloys. This process has evolved over the years, from low-pressure injection molds to casting molds at pressures of up to 4,500 psi. The process can create high-quality products with excellent end surfaces. Die Casting is an economical and efficient process for making various shapes. Considered superior to other manufacturing techniques, it is durable and aesthetic and combines perfectly with other parts of the machine that are part thereof. Dying has many advantages. Among these, the main is its ability to produce complex forms with a higher tolerance level than other mass-production methods. Thousands of identical prints can be produced before you need to add new mold tools. High Die-pressure is a manufacturing process where aluminum that has been melted is injected by a casting machine under extreme pressure on steel or molds to make the design and detail parts of the model you want to make. Casting in tons of universal tightening. This record reflects the amount of pressure given on the matrix. The engine size varies from 400 to 4000 tons. There are many advantages to using the die casting process compared to others. Die casting produces parts with thinner walls, narrower size limits and processes can be accelerated. Labor costs and finishing are the lowest with the dice. This process facilitates to obtain intricate forms with narrower tolerances. Unlike the forgery process, you can insert the kernel into the product created by this process. Forms that cannot be obtained from rods or tubes can be easily achieved with casting. The number of operational processes is smaller, which leads to the reduction of waste materials. Die casting is used when you need a stable, dimensional and durable component. They withstand heat and maintain a good level of tolerance, an important condition for each part of a good machine. They are stronger and lighter than the part made by other printing methods. Its parts are not welded or screwed, which greatly increases its efficiency. Another advantage is the many workarounds that you can get with the launch. Surfaces can be smooth or textured, which facilitates the application and its use. Hopefully, this information can help you and thank you for reading the article about Zinc Die casting.

Metal casting services involve the shaping of free-flowing liquid metals through the use of dies, molds, or patterns.  Castings are generally roughly finished due to the nature of their production.  In many cases, additional finishing is required to remove burrs and other artefacts of the casting process.  Metal castings services are used to design a wide range of components and finished products.  Everything from simple nails and fasteners to engine blocks can be fabricated using metal casting services.  Common metal casting processes include sand casting, die casting, permanent mold casting, investment casting, centrifugal casting, and lost foam casting. Sand Casting Sand casting is used to make large parts (typically iron, but also bronze, brass, aluminum). Molten metal is poured into a mold cavity formed out of sand (natural or synthetic). Sand castings generally have a rough surface, sometimes with surface impurities and surface variations. Die-casting includes a number of processes in which reusable dies or molds are used to produce casting.  The die contains an impression of the finished product together with it’s running, feeding and venting systems.  The die is capable of a regular cycle and of (quickly) dissipating the heat of the metal poured into it.  Once the liquid metal has cooled sufficiently, the mold is opened and the casting can be removed and finished. Permanent Mold Casting In permanent mold casting, molten metal is poured into cast iron molds, coated with a ceramic mold wash. Cores can be a metal, sand, sand shell, or other materials. When completed, the molds are opened and the castings are ejected.   Investment casting services involve molding patterns by the injection of a special wax into a metal die.  The patterns are assembled into a cluster around a wax runner system. The ‘tree’ of patterns is then coated with 8-10 layers of refractory material. The assembly is heated to remove the wax.  The hot mold is cast, and when cool, the mold material is removed by impact, vibration, grit blasting, high-pressure water blasting or chemical dissolution leaving the castings, which are then removed from the runner system. Centrifugal casting Centrifugal casting services are used to produce castings that are cylindrical in shape.  In centrifugal casting, a permanent mold is rotated about its axis at high speeds as the molten metal is poured. The molten metal is centrifugally thrown towards the inside mold wall, where it solidifies. The casting is usually a fine grain casting with a very fine-grained outer diameter, which is resistant to atmospheric corrosion, a typical need with pipes. The inside diameter has more impurities and inclusions, which can be machined away. Lost foam casting Lost foam casting (LFC) is metal casting services that use foam filled patterns to produce castings.  Foam is injected into a pattern, filling all areas, leaving no cavities.  When molten metal is injected into the pattern, the foam is burned off allowing the casting to take shape. Die casting Die casting and metal casting includes a number of processes in which reusable dies or molds are used to produce casting. The die is capable of a regular cycle and of (quickly) dissipating the heat of the metal poured into it. Once the liquid metal has cooled sufficiently, the mold or is opened and the casting can be removed and finished.   In the die casting process, molten metal is injected under pressure into a reusable mold or die. The die contains an impression of the casting together with it’s running, feeding and venting systems. The die is capable of a regular cycle and of (quickly) dissipating the heat of the metal poured into them. Once the liquid metal has cooled sufficiently, the mold or is opened and the metal casting can be removed and finished. high pressure die casting The high pressure die casting process is the most widely used, representing about 50% of all light alloy casting production. Low pressure die casting currently accounts for about 20% of production and its use is increasing. Gravity die casting accounts for the rest, with the exception of a small but growing contribution from the recently introduced vacuum die casting and squeeze casting process. the design of low pressure and gravity die casting dies for improved die filling, optimized solidification pattern and maximum yield. Gravity die-casting is suitable for mass production and for fully mechanized casting. Low-pressure die casting is especially suited to the production of components that are symmetric about an axis of rotation. Light automotive wheels are normally manufactured by this technique. Die casting metals can vary widely, and different die casting companies may have the ability to work with anyone or number of them. Some of the most common metal casting types include aluminum die casting, brass die casting, lead die casting (the most popular for model die casting), magnesium die casting, and zinc die casting.

Metal casting is highly crucial in modern manufacturing. It is technically shaping the whole world. As you know, you can create a wide range of metal parts from this method. High Pressure Die Casting is one of the most popular metal casting methods here. A typical metal casting method pours molten metal into a mold to create complex and precise shapes. Every industry needs these casting parts for many applications. They may need them for structural support or in their main products. One popular way to shape metal is through die-casting, and high pressure die casting is one of the most common die-casting methods. This method is what this article is mostly about. You will learn about how they are made, their benefits, and how they can be used. You will also find out how HPDC and LPDC are different. Overview of High Pressure Die Casting (HPDC) HPDC stands for High-Pressure Die Casting. As the name suggests, this metal casting method needs high pressure. HPDC casting is suitable for making many metal parts with high tolerances. In HPDC die casting, molten metal is injected into a steel mold or die at high speeds and pressure. As a result, you can create hundreds of casting parts in less time. The pressure needed here is to ensure that the molten metal fills the detailed feature of the die. Because of this, high-pressure die casting is suitable for high-volume production. An high pressure die casting machine is made up of several primary components. All of them are very important to the system. You might also find other parts, though. However, these four parts are the most important things in high pressure die casting process. They usually decide how good the casting parts are in the end. Die Cast Molds Die-cast molds, or dies, are high pressure die casting machine parts that generally determine the final shape. They have two main halves: stationery and movable. They are usually made from high-strength steel. Making these HPDC die-cast molds is called high pressure die casting tooling. Note that HPDC tooling is crucial for the best quality of metal casting. Ejector Pins Ejector Pins are another important components in high pressure die casting mold. They facilitate the removal of the solidified cast from the die. You can find these pins within the movable die half. Once your metal casting is cooled and solidified, you can actuate these pins to remove it. It mainly plays a crucial role in the production cycle. Cold chamber die casting machine Cold chamber die casting machine is a most important machinie which has injection system, press system, ejection systems and so on. all of die casting process will be done by this cold chamber die casting machine. Heating Components Heating components may include furnaces and heating elements. They typically do not melt the metal but keep the temperature constant. The main goal of this high pressure die casting machine part is to ensure the metal is in liquid form. Note that consistent heating is crucial for the quality and consistency of the final castings. How DoesHigh Pressure Die Casting Work? Generally, high pressure die casting works in five steps. Each step is crucial for the final quality of the castings. Therefore, when starting a die-casting process, always inspect the device. Check for any defects or loose screws. Always tune your device to its optimal settings. Check whether the cooling system is properly working or not. Once you have checked your device correctly, you can proceed to the primary high pressure die casting process. Always wear safety gear, such as gloves, clothes, and glasses. Step #1 Preparing the Die Cast Mold You can prepare the high pressure die casting mold in two main steps. First, if it has already been made, check it for defects and contamination before using it. Second, designing the mold is necessary for customized products. Designing a die-cast mold has several stages. First, you can draw your design using 3D software like SolidWorks, AutoCAD, and more. Ensure you have properly organized the gate runner and mold base when designing it. The cooling system is also a crucial part of this design process. Finally, check the venting & ejection system. Once you are done with the design, proceed with the draft analysis. You can check its functionality on various simulation software. After testing and quality inspection, you can use the die casting tooling for your final production. Step #2 Molten Metal Injection In this HPDC casting process, the machine injects molten metal into the die cavity. Unlike other methods, high-pressure casting uses high pressure and speed for this job, which is why it is called high-pressure die casting. First, tightly connect the two halves of the die-casting mold. Then, with a button push, the HPDC machine forces the molten metal into the chamber. This pressure technically ensures that the molten metal fills the entire cavity. Once the injection is done, the molten metal is allowed to cool and solidify. Two primary injection methods are used in the HPDC die-casting system. You can choose the correct method for the job based on your project needs. Hot Chamber Injection When your injection mechanism is immersed in the molten metal reservoir, it is called hot chamber injection. When the plunger moves, it draws the molten metal into the chamber and injects it into the die cavity. This type of injection is suitable for metals with low melting points. You may often find this hot chamber die casting machine is used zinc and magnesium alloys. Cold Chamber Injection Cold chamber injection, on the other hand, uses a separate melting furnace. You can pour the molten metal using a manual or automated system. In manufacturing, the automatic system is generally operated by a hydraulic plunger. It forces the molten metal to insert into the mold cavity. Cold chamber injection is a common technique for aluminum HPDC casting. Step #3 Cooling & Solidification After injection, the molten metal quickly cools within the die cavity. Some
