In the actual production, many similar test process as stamping is often to be used, such as the deep drawing performance test, bulging performance test and other test materials to ensure the quality of the product and high pass rate.
Stamping is the forming and processing method of the workpiece (stamping part) by the press and the mold to the plate, the strip, the tube and the profile and so on, which can cause the plastic deformation or separation to obtain the required shape and size. Stamping and forging belong to plastic processing (or pressure processing), collectively referred to as forging. Hot rolled and cold rolled steel plates and strips.
Stamping parts and castings, forgings, compared with a thin, uniform, light, strong characteristics. It can be used to make the workpiece, which is difficult to be manufactured, with stiffeners, ribs, ups and downs. Due to the use of precision molds, the workpiece precision can reach micron level, and high repetition accuracy, the same specifications, you can punch out holes, and so on.
Cold stamping parts are generally no longer cut, or only a small amount of cutting. The precision and surface state of hot stamping parts is lower than that of cold stamping parts, but it is still better than castings and forgings.
Stamping is a highly efficient production methods, the use of compound die, especially the multi station progressive die stamping process can be completed in a multi machine, realized by belt uncoiling, leveling, punching, forming and finishing automatic production. The production efficiency is high, the working condition is good, the production cost is low, generally can produce several hundred pieces per minute.
