What are the contents of metal stamping parts? Which fields are they mainly used in?

What is hardware? What is a stamping part? What are the widely used fields of metal stamping parts?

Hardware: parts processed from steel or some non-ferrous metals. Processing means: cold / hot stamping, extrusion, rolling, welding, cutting, and other processes. The definition is relatively wide.

Stamping parts: most commonly used in hardware processing, which means that steel / non-ferrous metal and other sheet metal molds are formed into specified shapes by the pressure required for processing provided by the press at room temperature.

Including some electronic devices, auto parts, decorative materials, etc. We usually say that stamping parts generally refer to cold stamping parts. For example, if you want to turn an iron plate into a fast-food plate, you must first design a set of molds. The working surface of the mold is the shape of the plate. Pressing the iron plate with the mold will turn it into the plate you want. This is cold stamping, that is, stamping hardware materials directly with the mold.
