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.

zinc Die Casting

zinc Die Casting

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.

magnesium die casting

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.

Magnesium die casting is a process in which the molten metal is forced to press under high pressure into the mould cavity using magnesium alloys. High pressure Die casting is one of the best technique widely used to create inexpensive metal parts for a variety of applications, especially magnesium casting products. The metal hardens to get the desired shape.

Magnesium is an excellent choice of die casting to distinguish between durable and durable products, providing a perfect combination of lightness, hardness and corrosion resistance to various casting applications. From concept to completion, with. Magnesium is also 100% recyclable, making it an attractive option when looking at the environment. Once the casting tool or die casting component reaches the end of its life, it can be easily recycled to serve a different purpose, thus saving costs and environmental impacts.

Magnesium is the lightest of all structural metals and is widely used in applications that require high-performance properties. In addition, the magnesium mass is almost equal to many plastics and has many advantages over plastics, including excellent toughness and corrosion resistance. The magnesium parts can be poured in a clean form and have a high ratio of strength to weight. Magnesium die casting can also be used in high-temperature applications

Magnesium is lightweight and has a strong structure for some casting components. Replacing magnesium components instead of heavy aluminium die casting products can help reduce fuel costs in vehicles where car manufacturers develop new techniques to use the unique properties of magnesium.

Advantages of magnesium die casting

There are numerous advantages to die casting part made in magnesium. Magnesium is not only the lightest in all structured materials, but it has excellent rigidity and strong weighting factors. In addition, it has distinct security properties, ideally suited for connectors and electrical buildings.

It has a low melting point

The low melting point makes magnesium much faster and energy efficient to melt without sacrificing the strength of the metal. Low temperature also provides faster cooling. The melting of magnesium is slightly higher than the usual aluminium alloy, making it very compatible with casting projects.

High dimensional accuracy and stability

The best strength/weight ratio for magnesium metal commonly used. Excellent dimensional stability, as well as high impact resistance and dent. The exceptional hydration capacity and low rigidity make it ideal for parts that undergo frequent and sudden changes in direction. High purity alloys can provide the latest best resistance to corrosion of carbon, steel and some aluminium alloys.

High electrical and thermal conductivity

Low heat content means that it requires less energy to reach the casting temperature, and castings are cooled more quickly so that the cycle time is faster. Low temperatures and low intimacy of iron reduce the impact of heat fatigue and corrosion on moulds so that they last longer.

Exceptional thin wall capability

magnesium die casting

Thin-walled die casting means systems can be manufactured as a single piece, rather than assembled from several components. This simplifies design, reduces assembly costs, improves reliability, reduces the cost of tools and reduces joints, clamps, and welds.

disadvantages of magnesium die casting

Special treatment methods and coatings are essential in determining the application of magnesium casting this is because Magnesium contains impurities, which means that the metal must be cleaned before pouring to remove impurities from the finished product.

Magnesium consumes a large amount of heat in solubility in preparation for die casting, The casting temperature, magnesium provides a much shorter lifespan than other alloys, which can increase production costs.

Since magnesium is easy to get fired, the magnesium dust of accessories in the workshop sometimes leads to initial blasting and fired, so there must be complete ventilation equipment in the processing workshop, including fine equipment such as dust collectors. Control the ignition source, fire prevention measures is the number one important thing when working with magnesium alloys.

Magnesium Die Casting

Casting is a process in which molten metal is poured into a mould that contains the intended shape. High pressure die casting (HPDC) is the most common method of Magnesium Die Casting and its alloys.

Magnesium is melted at a temperature of 923K and poured into crucibles where it is cooled under high pressure. The cooled magnesium solidifies and takes the shape of the crucible.

Magnesium has an inflexible hexagonal structure at its basic atomic level which makes it difficult to roll, stretch and shape. HPDC overcomes this limitation by offering an alternative, less difficult and faster method for manipulating
Magnesium.

Uses of Magnesium die casting

Magnesium is increasingly used in automotive and airplane manufacturers. This is due to its lightweight per unit volume. Casted Magnesium is also used in the manufacture of lightweight car seats, car bodies, and fuselage parts. The use is attributed to Magnesium is the lightest structural metal which can withstand greater column loading per unit weight.

Magnesium and its alloys are being used to manufacture chassis for appliances such as laptops, cameras, and phones.

Magnesium castings are also used in the manufacture of power tools such as chain saws, electric drills, and electric nail guns. The use of electrical appliances is gaining ground owing to its ability to conduct heat and electricity.

Advantages of high pressure die casting

Magnesium casting offers good finishing characteristics as minute details can be impressed onto the final product. High pressure dies casting is more economical compared to other methods of shaping Magnesium.

In this green era, the ability to recycle Magnesium makes High pressure die casting an environmentally friendly process. Magnesium metal is almost 100% recyclable thus reduces industrial junk.

Casted Magnesium alloys have high conductivity. There is marked improvement in the electrical and thermal conduction capabilities in Magnesium alloys making them suitable for use in electrical and thermal appliances.

Magnesium and its alloys can be cast into various shapes suited for different uses; Casting into thin walls can be achieved. Since Magnesium saves on weight without reducing durability, Magnesium thin walls are relatively stronger and lighter as compared to other metals of the same volume.

It has been noted that molten Magnesium has reduced affinity to iron thus can be cast in iron crucibles with a reduced risk in the final product acquiring iron impurities.

Casted Magnesium is resistant to corrosion by the elements, most notably, is the reduced susceptibility to Hydrogen porosity.

Disadvantages of high pressure die casting

Due to its very high melting point, melting Magnesium is both dangerous in safety and expensive process. A lot of energy is required to melt the Magnesium thus increasing the cost of production.

Moreover, the very high molten temperature of Magnesium can cause the liquid metal to take some of the iron from the crucible. Acquiring iron from the crucible is often undesirable as it would make the final product relatively impure.

Molten Magnesium is more viscous than other metals such as Aluminum. As a result, more pressure is required in the cooling process in an attempt to acquire the intended casting detail since cooling is often done under pressure.

To produce Magnesium die casting has high risk than producing Aluminium die casting, Magnesium is easy to get on fire since the ignition point is very low and it is hard to control this. this is why the cost is more expensive than Aluminum die casting. contact us to know more info.

Aluminum die casting

What is Aluminium die Casting

Aluminium die casting is a casting liquid die forging method. Die casting process is a kind of special high pressure die casting machine to accomplish the process. Its basic technological process is: first metal or aluminium alloy liquid in low or high-speed casting filling into the die mold cavity, die with a moveable type cavity surface.

It with the liquid aluminum alloy cooling process pressure forging blank, both the elimination of shrinkage defects, also make the rough internal Aluminum Die Casting organization to forge the broken crystal. Rough comprehensive mechanical properties are improved significantly.

Type of Casting process

Casting is the process of making Aluminium suitable for producing different types of products. It is a simple and inexpensive way to provide a wide variety of aluminium products. Some of the examples are Washington Monument, car engines, and power transmissions, etc, which were all produced through aluminum casting alloys process. Aluminium casting can be done in 3 ways:-

  1. Auminum die casting
  2. Mold Casting
  3. Sand Casting
  • DIE CASTING

Die casting is a manufacturing process for producing metal parts.  In die casting, die or mold cavities are created with hardened tool steel that has been previously machined to a particular shape. Here in die casting, Aluminium is melted first and is poured into a steel die under high pressure forcefully. This manufacturing technique is normally used for high volume production, the process we normally called high pressure die casting or pressure die casting process

  • MOLD CASTING

About mold casting, mold and cores can be of either steel or any other metal. Here also the aluminium is melted first and is poured in the mold provided. Sometimes vacuum is also applied. In some situations, Permanent mold casting is seemed to be stronger than both die casting and sand casting methods. Semi-permanent mold casting techniques are used when permanent cores are impossible to remove from the finished part.

  • SAND CASTING:

Sand casting is the most versatile method of producing aluminium products. Usually, the molted aluminium is poured into a mold which is virtually pressed into a fine sand mixture. The pattern will be little larger than which needed for the aluminium shrinkage during solidification and cooling. Sand Casting is usually a slow process than both die casting and mold casting. Usually, it is used for small quantity products.

Aluminum Casting Alloys

The most important cast aluminum casting alloys system is Al-Si. Here high levels of Silicon contribute to give good casting characteristics. aluminum casting alloys are widely used in engineering structures and components where lightweight or corrosion-resistant is required.
