A die-casting die is a tool for casting metal parts, a tool that completes the die-casting process on a dedicated die-casting die forging machine. The basic process of die casting is: the molten metal is first cast at low speed or high speed and filled into the cavity of the mold. The mold has a movable cavity surface. Loose defects also make the internal structure of the blank reach the broken grains in the forged state. The comprehensive mechanical properties of the blank are significantly improved.

Die-casting materials, die-casting machines, and molds are the three major elements of die-casting production, and none of them are indispensable. The so-called die-casting process is the organic and comprehensive application of these three elements, so as to stably, rhythmically and efficiently produce qualified castings with good appearance, good internal quality, and dimensions that meet the requirements of drawings or agreements, and even high-quality castings. .

The alloys used in die castings are mainly non-ferrous alloys, and ferrous metals (steel, iron, etc.) are rarely used due to problems such as mold materials. In non-ferrous alloy die castings, aluminum alloys are widely used, followed by zinc alloys. The following is a brief introduction to the situation of die-casting non-ferrous metals.
