[0002] Die casting is also called pressure casting. It is a special casting method with little cutting and has developed rapidly in modern metal processing technology. The products produced by this method have the advantages of high production efficiency, simple process, high casting tolerance grade, good surface roughness, high mechanical strength, and can save a lot of mechanical processing procedures and equipment, saving raw materials, etc. Therefore, it has become an important part of my country's foundry industry.
