Dimensional accuracy of metal stamping parts

The application of metal stamping parts is very extensive, involving all aspects of national life. Before stamping parts are processed, stamping factories need to understand the accuracy of stamping parts. Different stamping parts have different requirements for accuracy. Only when the customer's accuracy requirements are met, the stamping parts are qualified. Precision—30 years dedicated to the custom processing of precision stamping parts, let’s introduce the dimensional accuracy of metal stamping parts. The dimensional accuracy of metal stamping parts refers to the error between the specific dimensions of the metal stamping parts and the basic dimensions. The smaller the error, the higher the dimensional accuracy of the metal stamping parts. The key factors that cause the size deviation of the metal stamping parts are: the manufacturing accuracy of the concave and convex mold; the gap of the concave and convex mold cavity; the elastic recovery of the material after stamping; the accidental elements in the processing process, such as inaccurate positioning and unstable material characteristics, etc. . The process performance of metal stamping parts cannot be higher than the process performance of raw materials, otherwise the subsequent processing technology needs to be improved to achieve this, which increases the cost of the product. The dimensional accuracy of metal stamping parts can generally be divided into two categories: fine grade and ordinary. The fine level is the accuracy that can be achieved technically in the design of stamping dies, while the ordinary is the accuracy that can be achieved by economical means.
