Aluminum Die Casting is a method for creating aluminum parts that are well textured or smooth, and have a good surface finishing, and high dimensional stability. The reasons why aluminum is used for metal casting are as follows:
- High-speed production – thousands of identical castings can be manufactured with little to no machining.
- Dimensional accuracy and stability– with die casting, you can be confident that your parts are durable and dimensionally stable while maintaining close tolerances.
- Thin walls— die casting allows for the production of casts with thinner walls when compared to other methods Finishing options – whether you require a smooth or textured finish, die casting can produce parts that match your specifications.
- Lightweight parts – die casting is capable of producing parts for industries where weight is a concern, such asthe aerospace and automotive sectors.
- Improved performance– die casting parts are proven to improve general performance such as Mpg and vehicle
The two basic types of die casting equipment and machines; the hot chamber die casting machines and cold chamber die-casting machines, aluminum castings are processed in cold chamber machines. Because of the retention of the strength of aluminum alloy even at very elevated temperatures, it requires high pressure.
Therefore, the cast metal is melted in a separate furnace before being fed to the cold chamber machine. The machine then forces the molten metal into the mold using a pressurized plunger.
SIYUAN FOUNRY includes high pressure die casting and low pressure die casting.
