Steel or Aluminium Sandwich Die
1st, may duplicate replaces the bit, trades the knife number of times to reach above 30 times;
2, may realize the concave-convex position to be away from knife line smallest 1mm the die cutting to be continually concave-convex a formation craft;when
3, the manufacture die cutting is continually concave-convex a formation template, the pan may not use the hollow in the concave-convex position, strengthened mold's intensity and the stability;
4, the pan smoothness is high, favors the debugging to make up the pressure;
5, with the steel bottom die necessary use, improved the die cutting quality and the product quality effectively.
