ASP Punch Pin
ASP Punch Pins are precision-engineered tooling components made from advanced ASP powder metallurgy high-speed steel, designed for demanding metal forming and stamping applications. Unlike conventional punches, they combine high hardness with excellent toughness, ensuring stable performance under continuous impact and high-speed production conditions. These pins are widely used in progressive dies where accuracy and durability are critical. With refined heat treatment and precision grinding processes, they achieve consistent geometry and reliable punching stability.
- Wear Resistance: ASP steel (HRC 62–68) for long life.
- Precision: ±0.002 mm stable punching accuracy.
- Toughness: Resists cracking under impact loads.
- Efficiency: Stable for high-speed stamping lines.
Product Description
Introduction
ASP Punch Pins are high-performance precision tooling components manufactured from advanced powder metallurgy high-speed steel, including ASP23, ASP30, and ASP60 grades. They are specifically designed for demanding stamping die and progressive die applications where accuracy, durability, and stability are critical. Compared with conventional tool steel punches, ASP material offers significantly improved wear resistance, toughness, and dimensional stability under continuous production conditions.
These punch pins are produced through advanced CNC machining and precision grinding processes, ensuring tight tolerances up to ±0.002 mm and consistent geometry across all production batches. With hardness levels typically reaching HRC 62–68, ASP Punch Pins maintain excellent cutting performance even under high-speed and high-load stamping environments. Their refined microstructure reduces the risk of cracking and deformation, making them suitable for long-term industrial use.
Widely used in automotive, electronics, connector, and precision hardware manufacturing, ASP Punch Pins deliver reliable performance in complex stamping operations. They can be customized according to customer drawings, including different diameters, lengths, head shapes, and surface coatings such as TiN or TiCN. This flexibility makes them an ideal solution for OEM tooling requirements and high-volume production lines.
