Product Description
Introduction
Punch Pin is a precision-engineered tooling component widely used in stamping dies, progressive dies, and metal forming systems. It is designed for accurate punching, piercing, and forming operations where dimensional stability and repeatable performance are required. Manufactured from high-quality materials such as SKH51, SKH9, DC53, ASP steel, or tungsten carbide, Punch Pins provide excellent hardness, wear resistance, and durability for industrial production environments.
Through advanced CNC machining, precision grinding, and vacuum heat treatment processes, Punch Pins achieve tight dimensional tolerances up to ±0.002 mm. Their optimized structure ensures stable mechanical strength and consistent cutting performance even under high-speed and continuous stamping conditions. The precision-finished surface reduces friction, improves wear resistance, and enhances overall tooling efficiency in long-term operation.
Punch Pins are widely applied in automotive manufacturing, electronics, connectors, terminals, household appliances, and precision hardware industries. They are suitable for a variety of stamping processes including punching, forming, and piercing of metal sheets and components. Custom specifications such as diameter, length, head shape, material grade, and surface coatings like TiN or TiCN can be produced according to customer requirements. This flexibility makes Punch Pins a reliable solution for OEM tooling, non-standard die applications, and high-precision industrial manufacturing.
