Compared with general castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with ribs, ribs, undulations or flanging that are difficult to manufacture by other methods to improve their rigidity. Due to the use of precision molds, the accuracy of the workpiece can reach micron level, and the repeatability is high and the specifications are consistent, and holes, bosses, etc. can be punched out.
Cold stampings are generally no longer machined, or only require a small amount of machining. The accuracy and surface state of hot stamping parts are lower than those of cold stamping parts, but they are still better than castings and forgings, and the amount of machining is less.
