Typical working limit and Uchinuki’s working limit

In general, the working limit of perforated metals is plate thickness≦hole diameter or plate thickness≦bar.
Normally, it is impossible to make holes whose diameter is smaller than the plate thickness or make bars thinner than the plate thickness.
However, depending on the conditions, our company can make holes whose diameter is smaller than the plate thickness and bars thinner than the plate thickness.

Uchinuki’s metal mold manufacture

Uchinuki is manufacturing its original metal molds necessary for punching work. Even punching specifications not covered by our catalogue are possible at low prices by manufacturing a special metal mold. The customers may imagine that specifications not covered by our catalogue or website and special metal mold will naturally cost much, but low-cost manufacture is possible even in such a case.
Uchinuki can handle many patterns not covered by our website and catalogues.

Regarding processing beyond general working limits and special metal mold manufacture, please consult our sales department.
