Introduction to Die Casting Forging Process The die casting die forging process is a process performed on a dedicated die casting forging machine. The basic process is: the metal liquid is first filled into the cavity of the mold by low speed or high speed casting, and the mold has a movable cavity surface, which is pressed and forged with the cooling process of the molten metal, thereby eliminating the shrinkage of the blank. The loose defect also causes the internal structure of the blank to reach the forged broken grain. The overall mechanical properties of the blank are significantly improved. In addition, the blank produced by the process has an outer surface finish of 7 (Ra1.6), such as a cold extrusion process or a machined surface, with a metallic luster. Therefore, we call the die-casting forging process the “extreme forming process”, which is a step further than “no cutting, less residual forming process”. Another advantage of the die-casting forging process is that, in addition to producing conventional casting materials, it can also produce deformed alloys and forged alloys to produce highly complex parts. These alloy grades include: hard aluminum super-hard aluminum alloy, wrought aluminum alloy, such as LY11, LY12, 6061, 6063, LYC, LD, etc.). The tensile strength of these materials is nearly twice as high as that of ordinary cast alloys. It has a more positive significance for parts such as aluminum alloy automobile wheels and frames that are expected to be produced with higher strength and impact resistant materials.
