HSS Punch Pin
HSS Punch Pins are high-performance tooling parts used in stamping and forming systems. Made from high-speed steel, they combine strength and durability for industrial applications. Designed for continuous operation, they maintain stable geometry under stress. Precision machining and heat treatment ensure reliable quality, making them suitable for demanding die work requiring consistent output and long operational life.
Product Description
Introduction
HSS Punch Pins (High Speed Steel Punch Pins) are precision-engineered tooling components widely used in metal stamping dies and progressive die systems. Manufactured from premium high-speed steel grades such as M2, SKH51, and SKH9, they provide an excellent balance of hardness, toughness, and wear resistance. These punch pins are designed for stable and reliable performance in high-speed and continuous production environments.
Through advanced CNC machining and precision grinding processes, HSS Punch Pins achieve tight dimensional tolerances up to ±0.002 mm. The vacuum heat treatment process enhances material hardness to HRC 58–64 while maintaining good toughness, helping to reduce deformation and cracking during heavy-duty stamping operations. Their smooth surface finish also minimizes friction and improves overall punching efficiency.
HSS Punch Pins are widely applied in automotive manufacturing, electronics, connectors, terminals, and precision hardware industries. They are suitable for various stamping operations including punching, forming, and piercing. Custom specifications such as diameter, length, head shape, and coatings (TiN, TiCN, etc.) are available to meet OEM requirements, making them a reliable solution for demanding industrial tooling applications.
