Changzhou Metal Stamping Products Factory, other common problems + 16 strict quality inspections

The technicians of Changzhou Hardware Stamping Products Factory also talked about other common problems in stamping processing. Xiaoshuo collected some information, and let everyone know about it: Small (may exceed the specification requirements) and large difference from the punch size, in addition to considering the forming convex, concave mold design size, processing accuracy and blanking gap and other factors, the following aspects should also be considered to solve: ⑴. When the punching edge is worn, the tensile stress on the material increases, and the tendency of the stamping parts to turn over and twist increases. When turning over, the size of the punching hole will become smaller. ⑵. The strong pressure on the material causes plastic deformation of the material, which will cause the punching size to become larger. When the strong pressure is reduced, the punching size will become smaller. ⑶. The shape of the edge of the punch edge. If the end is trimmed with a slope or arc, the punching force will be slowed down, and the punching part will not be easily turned or twisted. Therefore, the punching size will become larger. When the end of the punch is flat (no bevel or arc), the size of the punching hole will be relatively small. Hardware, 15 years of ingenuity and focus on metal stamping parts processing, 20000+ sets of stamping die customization production experience, monthly 100+ sets of mold processing capacity, daily production capacity of 3 million punching times, stamping accuracy up to 0.01mm, 16 quality inspection layers are strict check. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
