Hardware stamping processing - advantages of stamping processing
08-21 / 2019

Compared with other methods of mechanical processing and plastic processing, stamping processing has many unique advantages in both technical and economic aspects.


The main manifestations are as follows:


(1) The production efficiency of stamping processing is high, and the operation is convenient, making it easy to achieve mechanization and automation. This is because stamping relies on dies and stamping equipment to complete the processing. The number of strokes of a regular press can reach tens of times per minute, and high-speed pressure can reach hundreds or even thousands of times per minute. Moreover, each stamping stroke may result in a stamping part.


(2) During stamping, because the die ensures the size and shape accuracy of the stamping part, and generally does not damage the surface quality of the stamping part, and the life of the die is generally long, the stamping quality is stable, the interchangeability is good, and the stamping is "exactly the same".


(3) Stamping can process parts with a wide range of dimensions and complex shapes, such as small stopwatches for clocks, large car longitudinal beams, covers, etc. In addition to the cold deformation hardening effect of the material during stamping, the strength and stiffness of stamping are both high.


(4) Stamping generally does not generate chips or debris, resulting in less material consumption and no need for other heating equipment. Therefore, it is a material saving and energy-saving processing method, and the cost of stamping parts is relatively low.
