Analysis of factors affecting the quality of stamping processing

Compared with other methods of mechanical processing and plastic processing, metal stamping parts have many unique advantages in both technical and economic aspects. The proportion of die-casting molds in the metal stamping parts processing industry will continue to increase. With the development of products such as vehicles and motors in the direction of lighter weight, higher and higher requirements will be put forward on the number, life and complexity of die-casting molds. With the development of replacing steel with plastic and wood with plastic and the continuous improvement of the precision and complexity of product parts, the proportion of plastic molds will continue to increase, and their precision and complexity will increase accordingly. Compared with castings and forgings, metal stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with reinforcing ribs, ribs, buckling or flanges that are difficult to manufacture by this skilled hand to improve its rigidity. Due to the rejection of rough molds, the precision of the workpiece can reach the micron level, and the precision is high, the specifications are consistent, and holes, bosses, etc. can be punched out. In actual production, process tests similar to the stamping process are commonly used, such as drawing performance test, bulging performance test, etc. to test the stamping performance of the material to ensure the quality of the finished product and a high pass rate. The precision and structure of the mold directly affect the forming and precision of the metal stamping parts. Mold manufacturing cost and life are important factors that affect the cost and quality of stamping parts. Mold design and manufacturing require more time, which prolongs the production preparation time of new stamping parts. Previous post: What is the key to metal stamping?
