How to deal with common faults of medical equipment stamping parts

In the daily production of medical device stamping parts, the size of the punching hole is too large or small, and the size of the punch is quite different. In addition to considering the design dimensions of the forming convex and concave dies, processing accuracy and punching clearance, etc. Weijun Precision Mold said that in addition to these, the following aspects should also be considered to solve.

1. The strong pressure on the material will cause the material to undergo plastic deformation, which will cause the size of the punching hole to become larger. When the strong pressure is reduced, the punching size will become smaller.

2. When the punching edge is worn, the tensile stress on the material increases, and the tendency of stamping parts to turn over and twist increases. When material turning occurs, the size of the punching hole will become smaller.

3. The shape of the cutting edge of the punch. If the end is trimmed with a slope or an arc, the punching force will be reduced and the punching will not be easily turned over and twisted, so the punching size will tend to be larger. However, when the end of the punch is flat (no slope or arc), the size of the punching hole will be relatively smaller.
