Pipe Fittings Rubber Expansion Joint

This is because stamping relies on punching dies and stamping equipment to complete the processing. The number of strokes of ordinary presses can reach several times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute, and each stamping stroke may be Get a punch. (2) During stamping, since the die ensures the size and shape accuracy of the stamping parts, and generally does not destroy the surface quality of the stamping parts, and the life of the die is generally long, the stamping quality is stable, the interchangeability is good, and it has a "pattern". Characteristics. (3) Stamping can process parts with a wide range of sizes and complex shapes, such as stopwatches as small as clocks, as large as automobile longitudinal beam covers, etc., plus the cold deformation hardening effect of the material during stamping, the strength and rigidity of stamping are equal. higher
