Stamping: Stamping is a process in which a sheet of metal is placed in a mold and then deformed into the desired shape through impact or pressure. In the stamping process, a stamping machine and a die are usually used, and the die presses the metal sheet into the desired shape, such as flat, curved, convex or concave, etc. Stamping is suitable for producing large quantities of sheet metal parts, such as automobile body parts, household appliance casings, etc.

Casting: Casting is a process in which molten metal is poured into a mold and solidified to obtain the desired shape. In the casting process, a metal mold or sand mold is usually used, and molten metal is injected into the mold. After the metal cools and solidifies, the mold is opened to obtain the casting. Casting is suitable for producing large, complex-shaped parts, such as engine blocks, mechanical parts, etc.

In general, stamping is suitable for the production of thin sheet metal parts and high-volume production, while casting is suitable for the production of large, complex-shaped parts and single-piece production.
