How are metal products stamped and formed?

The metal sheet is placed between the male mold and the female mold to be pressed and formed for processing the hollow shape, the depth can be deep or shallow. Punching: The process of punching and cutting a certain shape on the metal sheet with special tools can be applied to mass production. Punching: Basically similar to the punching process, the difference is that the former uses the punched part, while the latter uses the remaining part of the metal sheet after punching. Cutting: Cutting the metal sheet by cutting is the same as cutting the paper from the best position with a pair of scissors. Chip forming: When cutting metal, the cutting method with chip production is collectively called chip forming, including milling, drilling, lathe processing, grinding, sawing and other processes. No-chip molding: Use existing metal strips or metal sheets for molding. No chips are generated. Such processes include chemical processing, corrosion, electrical discharge processing, sandblasting, laser cutting, water jet cutting, and thermal cutting.
