What factors determine the accuracy of metal stamping

Metal stamping accuracy refers to the difference between the actual size of the metal stamping part and the basic size. The smaller the difference, the higher the dimensional accuracy presented by the metal stamping part. The existence of error is the fundamental reason for reducing the dimensional accuracy of metal stamping parts, and the dimensional error of metal stamping parts is caused by many factors. What are the factors that determine the accuracy of metal stamping? Actually, there are many factors that affect it, such as the blanking gap, die manufacturing accuracy, material properties and thickness, and the shape and size of the stamping parts. The main factor is the blanking gap. When the gap between the convex and concave dies is too large, the drawing effect of the material during the punching process is greater, so the drawing deformation is large. In principle, the surface quality of metal stamping parts cannot be higher than the surface quality of its raw materials, otherwise, subsequent processes must be added during processing, which will also increase the production cost of stamping parts. Judging from the dimensional error and surface quality, the dimensional accuracy of metal stamping parts can be divided into two types: precision level and ordinary level. Precision metal stamping parts are the accuracy that can be achieved in the stamping process technology, while the ordinary level is the accuracy that can be achieved by more economical means. When the mold manufacturing accuracy is high, the shape and dimension accuracy of the metal stamping parts can reach IT10 level, and the inner hole size can reach IT9 level. It can be seen that the manufacturing accuracy of the mold is the decisive factor for the dimensional accuracy of stamping parts. Equipped with original imported punching machines (Taiwan and Japan) equipment: metal stamping accuracy is high (punching accuracy is plus or minus 0.01MM), punching speed is fast (SPM1500), please feel free to bring drawings to our company for evaluation and quote.
