Punching or cutting paper, film or similar material with a blade of a prescribed shape (usually a Thomson blade) is called die cutting. The mold employed is usually referred to as a "die" .
This mold is typically made by incorporating a Thomson blade into a base of plywood or other material. However, Shin-Nihon Tech uses an integrated Thomson punch characterized by cutting a single piece of hardened material to form the blade.
This blade has a high hardness of at least HRC 56, which ensures that it will retain sharpness over a long working life. In addition, thanks to their high-speed machining center, the blade can be shaped to micrometer precision and cutting-edge height control.
When this integrated Thomson punch is incorporated into a progressive die, the press work can produce extremely fine die cutting.
