　　The difference between stamping and die casting

　　Stamping and die casting are two different metal processing techniques with distinct differences.

　　The processing principle is different. Stamping applies pressure to a metal sheet through a mold, causing it to undergo plastic deformation and obtain the desired shape and size of the part. Die casting is the process of injecting molten metal into the mold cavity under high pressure and solidifying it into shape.

　　In terms of materials, stamping is mainly used for sheet metal, such as steel plates, aluminum plates, etc. Die casting typically uses molten metal alloys such as aluminum alloys, zinc alloys, etc.

　　In terms of product characteristics, the accuracy and surface quality of stamped parts depend on the precision of the mold, and generally can achieve high precision and good surface smoothness. The internal structure of die-casting products is dense, but there may be defects such as pores.

　　In terms of molds, stamping molds have relatively simple structures and lower costs. Die casting molds are complex and require high temperature and pressure, resulting in high costs.

　　The application fields are also different, stamping is widely used in fields such as automotive casings and electrical casings. Die casting is commonly used for automotive engine components, electronic device casings, etc.

　　In terms of production efficiency, stamping production has a high efficiency and is suitable for mass production of simple shaped parts. Die casting is suitable for producing parts with complex shapes and thin walls, and has high production efficiency.
