Cold Heading Dies
Cold heading is a metal pressure processing technique that involves applying external force to metal at room temperature to shape it into a predetermined mold. This method is particularly suitable for the mass production of fasteners, such as hexagonal head bolts and cylindrical head internal hexagonal screws. Cold heading boasts several advantages, including a high steel utilization rate of 85% to 95%, high productivity, and excellent mechanical properties, making it ideal for automated production.
MH3 specializes in providing high-precision tungsten carbide molds and professional technical solutions tailored to customer designs and drawings. We ensure 100% product inspection and use high-precision equipment to deliver reliable product quality. Our one-stop service aims to meet and exceed customer expectations.
