Background

Die casting is a metal casting process and is characterized in that high pressure is applied to molten metal by utilizing an inner cavity of a die. The mold is typically machined from a stronger alloy, a process somewhat similar to injection molding. Most die cast parts are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of die casting, either a cold chamber die casting machine or a hot chamber die casting machine may be used.

The casting equipment and molds are expensive to manufacture, and therefore the die casting process is typically only used to mass produce a large number of products. It is relatively easy to manufacture die-cast parts, which typically require only four main steps, with a low incremental cost alone. Die casting is particularly suitable for manufacturing a large number of small and medium-sized castings, so die casting is the most widely used one of various casting processes. Compared with other casting technologies, the die-cast surface is smoother and has higher size consistency.

The die-casting die is a tool for casting metal parts, and is a tool for completing a die-casting process on a special die-casting die forging machine. The basic process of die casting comprises the following steps: molten metal is cast at low speed or high speed and filled into the cavity of the mold, the mold has movable cavity surface, and it is pressurized and forged along with the cooling process of the molten metal, so that the shrinkage cavity and shrinkage porosity defects of the blank are eliminated, and the internal structure of the blank reaches the broken crystal grains in the forged state. The comprehensive mechanical property of the blank is obviously improved.
