Punch

The piercing machine is the first deformation tool for steel pipe production, and its main function is to "shape". It is the most advanced guide plate conical piercing machine in the world, with good hole closure and stable deformation. After rolling, the capillary wall thickness is uniform, which can improve the wall thickness accuracy by 15%. At the same time, perforation defects are eliminated, and it can roll difficult to deform metals such as stainless steel, nickel chromium alloy, and thin-walled capillary.
