The die-casting pot is made of cold-rolled plate by servo imitating cold extrusion and numerical control processing. After cold extrusion, the internal structure of the plate crystallizes fine, with high strength and surface hardness. The unique thick bottom, thin wall, thick edge and other noble, elegant and quality features that ordinary non stick pot can't have. Compared with other technologies, the surface is smoother, which can reduce or avoid secondary mechanical addition The production speed is fast and the strength and quality are better.

Die casting is a kind of metal casting process, which is characterized by applying high pressure to molten metal by using die cavity. The mold is usually made of alloy with higher strength. This process is similar to injection molding.
