Zinc alloy die casting parts is a kind of pressure casting part. Zinc alloy die casting parts uses a pressure casting mechanical die casting machine equipped with a casting mold, which pours liquid zinc or zinc alloy into the inlet of the die casting machine. Then die casting parts by the die casting machine to produce zinc alloy die casting parts that are restricted by the shape and size of the mold.

Die casting is a metal casting process characterized by forcing molten metal under high pressure into the cavity. The mold cavity is made using two hardened tool steel molds that have been processed into a certain shape and work in a similar way to injection molds in the process. Most die castings are made of non-ferrous metals, especially zinc, copper, aluminum, magnesium, lead, tin and tin-based alloys. Depending on the type of metal being cast, hot or cold room machines are used.

Sand casting, also known as sand casting, is a metal casting process that uses sand as the mold material. The term "sand casting" can also refer to objects produced by the sand-casting process. Sand castings are produced by specialized foundries. More than 60% of metal castings are produced through sand casting processes.

Investment casting is an industrial process based on lost wax casting, which is one of the oldest known metal forming techniques. The term "lost wax casting" can also refer to modern investment casting processes.
