Die casting is a kind of metal casting process, which is characterized by applying high pressure to molten metal by using the inner cavity of the mold. Molds are usually made of higher strength alloys, a process somewhat similar to injection molding. Most die castings are iron free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead tin alloys and their alloys. According to the different types of die casting, cold chamber die casting machine or hot chamber die casting machine should be used.

HCVAC vacuum coating machine, applied in die casting industry, greatly improves wear resistance, prolongs service life and durability of components, and provides emergency operation reserve, which can improve performance, reliability and compact design. Super hard, extremely corrosion-resistant and wear-resistant coating is an important factor to protect the die from welding and premature fire cracking. Maintenance costs and scrap rates are greatly reduced. Therefore, the coating has made a valuable contribution to reliable die casting process and ensured product quality and productivity.
