What are the advantages of hydroforming of auto parts?

At present, the mainstream stamping process in China is still the linear mold production mode. As for special forming processes, such as hydroforming, we often hear similar introductions and reports, but they are still mainly in the laboratory state.

The hydroforming technology in the industry is mainly used in the forming of tubular parts, and in foreign countries, it is mainly used in the manufacture of small batches of personalized auto parts. At present, there is no china application in the forming of cover parts.

Hydroforming has more prominent advantages: First of all, in principle, this technology is isobaric forming, which relies on high-pressure medium to change the shape of the sheet. It can improve local forming, or it is beneficial to form more complex covering parts; secondly, its forming principle and liquid medium change the traditional steel-steel contact forming method, which can effectively reduce sheet scratches, which is extremely beneficial to improving surface quality. 3. The limitation of traditional stamping on the direction of stamping is improved; 4. More process content can be formed at one time, which is conducive to reducing the number of processes and molds; At the same time, judging from the current foreign application situation, its production rhythm is not slow.

However, hydroforming technology also has its shortcomings. The limitations of its application are obvious: external liquid medium and its corresponding device are required; and it is necessary to carry out post-fabrication of parts before welding; considering the impact on the field operation environment, it is not suitable for mass parts fabrication.
