Cold forming is a metalworking process which incorporates the extruding and upsetting of raw material wire into a finished part through a series of punches and dies. An important consideration in heading is the length to diameter ratio. Standard ratios are approximately 3:1 but are dependent upon the sophistication of the tooling.
Hardness   Hardness
With the cold forming process, raw material wire at room temperature is headed under high forging tonnage beyond its limits of elasticity into a net or near net shape part. In forming the part, the grain structure flow lines are not disturbed as they would be in a cutting process. The inherent result is a stronger finished part.

Cold forming is different from hot forming, where the metal is heated before processing. In cold forming, the metal is formed into a shape at room temperature. Complex tool design and tooling allow for production of various combinations of extrusion and upsetting as the raw material travels through the punches and dies of a cold forming machine. Strict tolerances and surface finishes can exceed those achieved with machining.
Low Cost   Low Cost
Production costs are reduced through the high speed cold forming process.Speeds can range from 100 pieces per minute up to 400 pieces per minute depending upon size and configuration of the finished part. The cold forming process achieves significant material cost savings by avoiding the generation of scrap that is found in the machining process.
