Some stamping processes are used to punch holes in large quantities. Metal stamping can be used. For example, if you decide to use hydroforming for other reasons, you need to use a separate process to punch holes in the parts, which can be costly.
1, metal stamping processing of high production efficiency, and convenient operation, easy to realize mechanization and automation. This is because stamping is dependent on stamping die and stamping equipment to complete the processing, the number of travel of the ordinary press can reach dozens of times per minute, the high-speed pressure can reach hundreds of times or even more than 1,000 times per minute, and each stamping stroke may get a punch.
2, metal stamping because the mold 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 mold is generally long, so the quality of the stamping is stable, the interchangeability is good, and it has the characteristics of "identical".
3, metal stamping can be processed into a large range of size, the shape of the complex parts, such as small to the stopwatch of the clock, large to the car rail, covering parts, etc., coupled with the cold deformation hardening effect of the material when stamping, metal stamping strength and stiffness are high.
4, metal stamping is generally not generated chip, material consumption is less, and does not need other heating equipment, so it is a kind of material saving, energy saving processing method, the cost of stamping parts is low.
Metal stamping has several disadvantages:
1, the early tool cost is high. If you're doing small batches, upfront tooling costs can make it expensive. The metal stamping process requires two dies, one concave and one convex.
2. Longer lead time. It takes more time to design and manufacture two molds instead of one.
3. More scrap metal. For metal stamping, the sheet metal must overlap the die a little. This creates more scrap metal than other processes.
Despite these drawbacks, metal stamping is still a good solution. Sheet metal stamping is a very common process, and in fact, metal stamping is part of the production process for most automotive parts. For many types of parts, the stamping process is preferred by companies around the world.
