Hydroforming is a shaping technology that refers to the use of liquids or molds to shape workpieces, also known as hydraulic forming. Hydroforming technology can do many stamping processes, such as punching, bending, stretching, etc. Using hydroforming technology, stamping processing plants can process a variety of complex stamping parts, such as bellows. The stamping products produced by hydroforming have the advantages of good surface quality, simplified process and simplified molds, which greatly simplifies the processing procedures of the stamping processing plant. However, because the liquid directly acts on the stamping parts, it is much more difficult to achieve the sealing requirements, and the operation process is more complicated.

Hydroforming has outstanding advantages:

1. This technology is isostatic forming, which relies on high-pressure media to change the shape of the sheet. The raw material is compressed in the normal direction and is under stress in three directions, which can better perform partial forming and make it easier to process more complex stamping parts;

2. The traditional steel-steel contact forming method is changed, which can effectively reduce the scratches of stamping products and optimize the appearance of the product to a large extent.

3. Break through the limitations of traditional stamping in the forming direction of stamping parts.

4. Multiple processes can be carried out at once, which is beneficial to reduce the number of processes and molds.
