Custom Aluminium Alloy Die Casting Auto Engine Parts

 Aluminium Alloy Die Casting Auto Engine Parts for Machine, the part is a housing for Auto engine system which is applied to bus, the part is a cover.In die casting process. shrinkage is a serious problem. should be careful. The reason for shrinkage is that the liquid density of most casting metals is slightly lower than that of solid density. This means that the volume of the metal decreases during the curing process. As long as the liquid metal can enter the casting before curing, it will minimize the shrinkage phenomenon. Unfortunately, because of the many different cross-sections of the casting, the "die hot spot" is inevitable. This part of the casting remains liquid after the other part is solidified, so it shrinks when solidified. The best way to solve the shrinkage problem is to improve the design of cavity, strengthening pressure and metal temperature. The part has request on surface finish of E-Coating to satisfy the daily application, so t…
