Vacuum Die Casting
Vacuum casting begins in the half-century before, now is very popular in the auto industry. the mechanical property is not very strong by normal aluminum casting methods. When a customer has a strict request for the components of their products, such as high-pressure testing request parts and thin wall or even structure complicate products will need vacuum casting, our factory has over ten years vacuum casting experiences, the aluminum casting parts produced by us with nice surface and strength property, casting products by this kind production methods can take secondly heat treatment, the harness of parts can reach 50HRC degree. This kind of production method will greatly reduce the air porosity problem. The casting parts by vacuum production process can work in a high-temperature environment. Vacuum casting can use in aluminum, zinc, brass. For example, for the normal size zinc die casting parts the wall thickness is minimum only 0.8mm. The wall thickness minimum can reduce to 0.5mm when casting by vacuum condition, the production efficiency will increasing 10% when casting by the vacuum production process. The parts will ejector from the mold cavity a bit fast than the normal die casting process.
