Automotive stamping parts production involves special stamping technology as automotive stamping parts, their technical requirements is moving toward the edge of a complex structure, the block size increases, the related parts, bearing capacity and more strictly limited internal stress direction, such as this to a certain extent, also played a significant role in special stamping technology.

The so-called special stamping technology, refers to hydraulic forming, precision forming, explosive forming, spinning forming, formless forming, laser forming and electromagnetic forming technology, etc.Hydraulic internal high pressure forming technology is more advantageous than other stamping forming technology.

In the production of automotive stamping parts, hydraulic internal high-pressure forming process can be a time to process such as axle, roof plate, door frame and other large complex three-dimensional geometric shape of the workpiece;And because of the cooling effect of the liquid in the forming process, the workpiece is strengthened by cold work to obtain higher workpiece strength than general stamping processing, which allows the use of thinner plate, to achieve the goal of lightweight automotive stamping.

Due to the automobile stamping parts in the hydraulic internal high-pressure forming process, the outer surface of the plate only contact with the pressure liquid, the process of pressure is relatively gentle, the forming of parts change evenly, so can obtain a symmetrical pressure distribution, and can get a much better smooth surface.

In addition, through the hydraulic internal high-pressure forming technology to produce automotive stamping parts, not only save the cost, and shorten the time, can achieve the product mass production.In addition, electromagnetic forming technology is also a special forming technology used in automobile stamping parts, which is more prominent in the aspects of forming speed, environmental protection and energy saving.
