Cold Forming : Introduction

Cold forming is a manufacturing process that plastically deforms metal using dies. It allows for high speed production, little to no material waste compared to conventional machining, and creates a stronger end product due to work hardening of the material.

Advantages of Cold Forming

Material Yield Rate
(multi-step rivet example)

High efficiency material utilization (high yield)  

The high material utilization of cold forging allows for significant reductions in material waste (scrap) compared to machining for the same geometry.

Production Speed
(multi-step rivet example)

Higher speed, more efficient production

Cold forming allows for high speed manufacturing (around 100 parts/minute) while still maintaining high precision and complex product geometries. No heating of the material is required.

Fiber Flow Lines
(multi-step rivet example)

Improved product strength by work hardening

Cold forming process design takes fiber flow lines (the crystal structure of metals) into account allowing for stronger more durable parts.

Cost reductions through customized manufacturing processes  

If a customer design(toleranc es, geometry, number of components required, etc) is practical using cold forming, significant improvements in part unit cost and reduced process complexity are possible.
