The difference between the design of the welded pipe mold of the stainless steel pipe making machine and the high-frequency pipe welding machine is mainly the difference in the forming method and size, and there are also some differences in the choice of materials.

The welded pipe mold of the stainless steel pipe making machine is generally designed by the rapid forming method, such as square tube and rectangular tube, which is obtained by directly performing the compact forming at the position of the straightening head, and there are only a few units of the stainless steel pipe making machine that have one straighten head. Then this welded pipe mold needs to be designed by slow forming, and the deformation design of the mold should be started in the sizing section.

The welded pipe mold of the high frequency pipe welding machine is generally designed by the slow forming method. Because the production speed of the high frequency pipe welding machine is very fast, if the welded pipe mold is designed by the rapid molding method, it will cause great damage to the mold, and at the same time, many of the produced pipe materials will have flaws in the strain, causing a lot of damage. This is not worthwhile, so slow molding is generally used.
