The metal stamping parts have light weight, thin thickness and good rigidity. Its dimensional tolerance is guaranteed by the mold, so the quality is stable, and generally it can be used without mechanical cutting. The metal structure and mechanical properties of cold stamping parts are better than the original blanks, and the surface is smooth and beautiful. The tolerance level and surface condition of cold stamping parts are better than hot stamping parts.

    The process and equipment of metal stamping production are constantly developing. In addition to the traditional use of presses and steel molds to manufacture stamping parts, various special features such as hydroforming, spinning forming, superplastic forming, explosive forming, electro-hydraulic forming, electromagnetic forming, etc. The stamping process has also developed rapidly, which has raised the technical level of stamping to a new level. The special stamping forming process is particularly suitable for the production of a variety of small and medium batches (even dozens of pieces) of parts. For ordinary stamping processes, simple molds, low melting point alloy molds, group molds and stamping flexible manufacturing systems can be used to organize the stamping processing of a variety of small and medium-sized parts. High-volume stamping production of small and medium-sized parts generally uses compound molds or multi-station continuous molds. With modern high-speed multi-station press as the center, it is equipped with strip uncoiling, straightening, finished product collection, conveying, mold library and quick mold change device, and controlled by computer program, it can form a fully automatic stamping production line with high productivity. Using new mold materials and various surface treatment technologies to improve the mold structure can obtain high-precision, long-life stamping dies, thereby improving the quality of stamping parts and reducing the manufacturing cost of metal stamping parts.

    In short, metal stamping has a series of advantages such as high productivity, low processing cost, high material utilization, simple operation, and easy realization of mechanization and automation. The use of composite processes such as stamping, welding, and gluing makes the structure of the parts more reasonable, and the processing is more convenient. A simpler process can be used to produce more complex die-casting structural parts.
