How Does Adjusting Punch Geometry Prevent Cracking and Chipping in High-Stress Cold Heading?

This technical analysis explains how Adjusting Punch Geometry directly resolves the common issues of cracking and chipping in cold heading tools. By focusing on the optimization of chamfers, transition radii, and load distribution, manufacturers can prevent stress concentration that leads to premature failure. The article highlights how geometry works in tandem with high-hardness materials (HRC 50–65) and surface coatings to extend tool life by 1.5–2 times. Backed by real-world case studies, it provides a practical roadmap for procurement managers to improve line stability and reduce scrap rates.
