Most defects on Aluminum Die Casting Parts Tooling components do not occur when grooves are opened in castings or when companies perform analytical machining. The reason is that the fine-grained layer structure on the surface of the casting is cut off, exposing the coarse-grained area that develops and extends to the center, and all shrinkage cavities are located under this skin layer. Once the outer surface of the casting is defective, casting leakage occurs under pressure. If the surface of the casting is unprocessed, its internal holes have no direct effect on the pressure resistance.

Pressure temperature has a significant effect on pressure resistance, lower temperature-pressure, higher pressure resistance, this is because of the casting surface and the dense surface layer at low temperature. The fillet at the junction of two or more angular intersecting surfaces in China is the part where information leakage often occurs in the casting process, because these parts are generally hot nodes in the molding, forming a thinner surface layer. Increasing the corner radius exacerbates this phenomenon due to the higher temperature of the Aluminum Die Casting Parts Tooling components and the thinner casting surfaces.

Die casting alloys also have an effect on the types of leaks that Aluminum Die Casting Parts Tooling components typically do more than zinc castings. Little is known about leaks within castings or information leaks between two major machining surfaces, and it is likely that the type of holes rather than the number of holes determines whether a company can have an impact on such system leaks. It is very difficult to conclude who will have the ability to manufacture large die castings, the impregnation process is essential.
