What is the dimensional accuracy of metal stamping parts?

The dimensional accuracy of metal stamping parts is measured by tolerance registration. The national standard stipulates that it is divided into 20 levels, from IT01, IT0, IT1, IT2 to IT18. The larger the number, the lower the tolerance level (processing accuracy), and the allowable change in size The larger the range (tolerance value), the smaller the processing difficulty. The dimensional accuracy of metal stamping parts refers to the difference between the actual size of the stamping part and the basic size. The smaller the difference, the higher the dimensional accuracy of the metal stamping part. The main factors that cause dimensional errors of metal stamping parts are: the manufacturing accuracy of convex and concave molds; the gap between convex and concave molds; the elastic recovery of materials after stamping; accidental factors in the production process, such as inaccurate positioning and unstable material properties. The dimensional accuracy of metal stamping parts can generally be divided into two categories: ordinary level and precision level. The ordinary level is the accuracy that can be achieved by more economical means. The precision level is the precision that can be achieved technically in the stamping process.
