How to make the tolerance of metal stamping parts reach 0.02mm-hardware

How does hardware make the tolerance of metal stamping parts up to 0.02mm? The dimensional accuracy of precision metal stamping parts is the result of 15 years of continuous efforts to grow, and we strive for perfection in every detail of our customers. The lower the tolerance level (processing accuracy), the larger the allowable range of size (tolerance value) and 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 surface quality of the metal stamping parts cannot be higher than the surface quality of the raw materials, otherwise the subsequent processing needs to be increased to achieve it, which will increase the production cost. 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 in the stamping process technology. For the hardware company mainly engaged in precision stamping, the product size needs to be controlled within +/-0.02mm. Walk in and understand
