Progressive dies for auto parts are gaining momentum

With the development of high efficiency and automation in automotive stamping production, the application of progressive die production for automotive parts will become more widespread. Complicated shape stamping parts, especially some small and medium-sized complicated stamping parts that require multiple punching dies in different processes according to traditional processes, will increasingly be formed by multi-station progressive dies. For example, the 14-station progressive die for automobile window shaker parts, the stamping material of 1mm thick high-strength steel plate, uses multi-station progressive die to form products, instead of the original production requires 5 sub-process molds, and the production efficiency is increased by more than 3 times , The mold life is up to 30 million strokes. 19-station progressive die for automobile frame parts, high-strength plates of 2.6mm thick stamping material, one die for forming the left and right parts instead of one die. Large-scale progressive die for automobile structural parts, with complex product shapes, large surface depth fluctuations, and high precision. The level of these molds and the quality of stamping parts are comparable to those of similar foreign ones.
