Did You Know??
Cold forming and heading creates a strong, “forged” part where the material grains are compressed, aligned, and conformed to one another, as well as conformed to the part geometry in a uniform flow pattern. This greatly increases the shear and torsion strength of the part through “work hardening”. In many cases, this work hardening effect can negate the need for a post processing heat treatment depending on the application requirements and the material selected.
Cold Forming…When CNC Just Doesn’t Cut It…
Cold forming is a process similar to forging, but is performed on metallic materials at or near room temperatures. Using this process, a metal blank is cut from wire stock then formed at high speed and pressure using tool steel or carbide dies. There are many advantages of this forming process…Download PDF
“Virtual Design” of Cold Formed Parts Using Finite Element Analysis
Finite Element Analysis (or FEA) is an engineering technique using computer software to accurately predict the performance of a mechanical component design under real world conditions. The word “element” in the phrase “finite element analysis” offers a clue to how this software actually works…Download PDF
Graded Microstructures in Cold Formed Metallic Components
The room temperature forming of metallic materials enables the design of components that possess tailored, graded mechanical properties. During the room temperature forming process known as “cold heading”, forces are imparted to a cylindrical metal slug resulting in plastic flow of the material…Download PDF
