Die casting is a metal casting process that uses the cavity of a mold to apply high pressure to molten metal. Molds are usually made of higher-strength alloys, and this process is somewhat similar to injection molding. Most die castings do not contain iron, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, you need to use a cold chamber die casting machine or a hot chamber die casting machine.

The cost of casting equipment and molds is high, so the die-casting process is generally only used for mass production of a large number of products. quality die casting 。It is relatively easy to manufacture die-casting parts, generally only four main steps are required, and the individual cost increment is very low. Die casting is particularly suitable for the manufacture of a large number of small and medium-sized castings, so die casting is the most widely used in various casting processes. Compared with other casting technologies, the die-casting surface is flatter and the size consistency is higher.

Based on the traditional die-casting process, several improved processes were born, including a non-porous die-casting process that reduces casting defects and eliminates porosity. It is mainly used for processing zinc, which can reduce waste and increase the output of direct injection process.
