Stamping parts are the parts produced by press machine and mold enforcing on the plates, strips, tubes and profiles to make the parts deformational or separated, finally obtain required shapes and sizes. Stamping and forging are both plastic processing like stamping parts or forging parts (and pressure processing), collectively known as forging. The materials of stamping parts are mainly hot and cold rolling of steel sheets and strips.
In the world's steel, 60 ~ 70% of that are the plate, most of which are made through the stamping parts. Vehicle body, chassis, fuel tank, radiator, boiler drum, the container shell, motors, electrical appliances are all core stamping silicon processing. There are also a large number of stamping parts in the instruments, household appliances, bicycles, office machinery, utensils and other products in life,.
Compared with castings parts and forging parts, stamping parts have some features such as thin, uniform, light, and strong. The stamping can produce the stamping parts with ribs, rolling or burring which are hard to manufacture by other methods. As a result of precision molds, the precision of stamping parts can reach up to micron level, and high repetition accuracy, the same specifications, can punch a hole nest, boss and so on.
Generally, the cold stamping parts have not been machining, or only need a small amount of cutting. Hot stamping parts precision and surface state below the cold stamping parts, but still better than the castings, forgings, machining less.
The stamping parts will be convenient to use in the processing. Stamping is a method to make highly efficient stamping parts, achieving with the material from the coil, flattening, punching to forming, finishing the whole automated production. High efficiency, good working conditions, low production costs, the general can produce hundreds of stamping parts per minute.
