Dimensional accuracy of metal stamping parts for auto parts-hardware

Metal stamping parts are widely used in various areas of our lives, including some electronic devices, auto parts, metal stamping parts, decorative materials and so on. The hardness test of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes can be used to test the surface is very small, can not be tested on the ordinary desktop Rockwell hardness tester. Next, the author will introduce what is the dimensional accuracy of metal stamping parts? 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 should not be higher than the surface quality of the raw materials, otherwise the subsequent processing needs to be increased to achieve this, which increases the production cost.
