Perforating Tools TRIZ Cases

An asymmetric through-hole geometry retains slug waste in the collection container, preventing damage from falling material and eliminating vacuum systems.

Segmented punch blades overlap notches and punches to eliminate projection seams at hole ends, ensuring complete material removal.

Curved die shoulders and angled punches improve punching hole expandability in high strength steel by managing stress distribution.

Uniform cutting edge sharpness and increased clearance reduce punching forces and chipping in thick stainless steel.

A nut with a non-circular opening contour prevents co-rotation on the bolt.
