The Four Steps of the Die Casting Process. The die casting procedure is a hard task, though in the end, it can be very satisfying. Essentially, it is the method of subjecting a molten metal to high pressure in order to produce mold cavities. These mold cavities are ultimately transformed into dies. Die casting can only be done with metals, the most accepted kinds being tin, lead, magnesium, copper, zinc, aluminium, and their alloys. Non-ferrous metals are the suggested kinds for die casting. As a whole, die casting is typically done when little or medium-sized metal parts are crucial, and need high-quality detail, dimensional reliability and a very fine surface quality. In the metalworking industry, the die casting process is enormously popular mostly because of its versatility.
One thing that die casting has to struggle with, however, is the procedure of injection-molding plastic parts. People who would rather settle for cheaper things of lower quality are now turning to plastic instead of metal. Nonetheless, when it comes to house parts and comparable materials, die casting remains as the leading practice for little structures.
The die casting process can be abridged in four chief steps. First of all, the mold needs to be sprayed with an amount of lubricant and then closed, for the lubricant will help control the die’s temperature, as well as help in removing the casting. Then, the molten metal is put into the die under a very high pressure. The pressure must be preserved until the casting is hardened. After opening the die, the shot, using ejector pins, is removed, and then the scrap is removed from the castings.
