Processing principles that metal stamping parts manufacturers need to follow

When metal stamping parts manufacturers are stamping, they need different processing techniques to meet the dimensions and specifications of stamping parts required by customers. Guangdong Precision-Committed to precision metal stamping and metal insert injection molding for more than 10 years, with rich processing experience. Here is an introduction to the processing principles that manufacturers of metal stamping parts need to follow. 1. When the section quality and dimensional accuracy of the stamping parts are required to be high, please consider adding a trimming process after the punching process or directly adopting a precision blanking process. 2. The stamping parts with simple shapes are blanked and finished with a single-process mold. For workpieces with complex shapes, the inner and outer contours of the mold should be divided into several parts due to the restriction of the structure or strength of the mold, which requires multiple stamping processes. If necessary, continuous mode can be selected. For precision metal stamping parts with high flatness requirements, the leveling process can be added after the punching process. 3. The number of processes for drawing parts is related to the material properties, drawing height, number of drawing steps, drawing diameter, material thickness and other conditions, which can be determined by drawing process calculations. When the rounded corner radius of the drawn part is small or the dimensional accuracy is high, it is necessary to increase the shaping process after drawing. 4. The number of processes for the bending part mainly depends on the complexity of its structure and shape, as well as the number of bending angles, relative positions and bending directions. When the bending radius of the bending piece is less than the allowable value, a shaping process is added after bending. 5. In order to improve the stability of the stamping process, sometimes it is necessary to increase the number of processes to ensure the quality of stamping parts. For example, the additional positioning process hole punching of the bent part, the increased deformation in the forming process, the reduction of the hole punching to transfer the deformation zone, and so on.
