Tool Punch Press

Unitized tooling is a system of self-contained metalworking units with common die heights and shut heights. Each unit has its own strippers and stripping springs, so it can be used next to other similar tools. These units are secured to a mounting system for installation into a press or press brake.
Typical functions, in addition to punching holes, include notching, forming radii on corners, edge-notching, edge-forming, lancing, and so on.
In addition to working with flat metal, plastic, and even glass, unitized tooling is widely used to punch or notch structural shapes such as channel iron or angle iron. It's also widely used to punch holes and notches in oddly shaped aluminum extrusions.
