Minimum Deform Stipper Assembly

A punching attachment designed to reduce distortion in the workpiece during punching, helping keep flat bar and strip material straighter across repeated holes. 

When punching multiple holes, material can bow or warp as force is applied and released. A minimum deform setup helps reduce that effect and can cut down on rework and straightening time. 

It’s intended for the Compact range of Kingsland steelworkers.

High-volume hole punching, long lengths of flat bar/strip, and jobs where straightness and repeatable positioning matter.

These systems typically apply pressure more evenly across the material during the punching cycle, which helps reduce sudden movement and deformation. 

Bracket runs, rails, frames, cleats, repetitive fixing patterns, and structural fabrication parts where alignment matters over length.

Steelworker model, material type and thickness, hole diameter range, and whether you’re punching single holes or repeated patterns along long lengths.
