Aluminum Die Casting and Zinc Die Casting
What Is Die Casting?
Die casting is a metal casting process characterized by pressuring molten metal into the mold cavity. The mold cavity is created using two hardened tool steel molds that are machined during processing and work similarly to injection molds. Most die-castings are made from non-ferrous metals, especially zinc, copper, aluminum, magnesium, lead, tin and tin-based alloys. Depending on the type of metal being cast, thermal or cold machines are used.
How are Die Castings Made?
Steel dies capable of producing tens of thousands of castings in quick succession must be made in at least two sections to allow the castings to be removed. These parts are firmly mounted in the machine and are arranged so that one is stationary (fixed die half) and the other one is movable (syringe half-mold). To begin the casting cycle, the two mold halves are clamped together by a die-casting machine. Molten metal is injected into the mold cavity and rapidly solidified. The mold half is opened and the casting is ejected. Die-casting molds can be simple or complicated, with moveable slides, cores or other parts, depending on the complexity of the casting.
To date, the complete cycle of die casting has been the fastest cycle to produce precision nonferrous metal parts. This is in stark contrast to sand casting, which requires new sand molds for each casting. Although the permanent mold process uses iron or steel molds instead of sand, it is much slower and less precise than die castings.
