Precision stamping differs from ordinary stamping in that precision stamping usually refers to one-time forming, minimizing post-stamping processing, while ordinary stamping still requires post-processing after stamping.
Stamping is a production technology that uses conventional or specialized stamping equipment to directly deform sheet metal in a mold to obtain products with certain shapes, dimensions, and properties.
Stamping technology, molds, stamping equipment, and stamping materials are the three elements of stamping processing. Only by combining them can stamping parts be obtained.
Compared with other methods of mechanical and plastic processing, precision stamping has many unique advantages, mainly reflected in the following aspects:
The production efficiency of stamping is high, and it is easy to realize mechanization and automation. This is because stamping relies on stamping dies and stamping equipment to complete the processing. The number of strokes of ordinary presses can reach dozens per minute, and high-speed presses can reach hundreds or even thousands of strokes per minute, and each stroke may produce a stamping part.
During precision stamping, the mold ensures the dimensional and shape accuracy of the stamping parts and generally does not damage the surface quality of precision stamping parts, and the life of the mold is generally long. Therefore, the quality of stamping is stable, with good interchangeability and the feature of "one die, one same".
Precision stamping can produce parts with a larger size range and more complex shapes, such as stopwatch for watches and clocks, as well as automotive longitudinal beams and cover parts. Coupled with the cold deformation hardening effect of the material during stamping, the strength and rigidity of the stamping are relatively high.
Precision stamping generates generally no scrap or fragment material, consumes less material, and does not require other heating equipment, making it a low-cost, material-saving, and energy-saving processing method. Because of its superiority, stamping technology is widely used in various fields of the national economy.
