Product Description
Introduction
Stainless Punch Pin is a precision tooling component designed for stamping dies and mold systems, specifically used for punching and forming stainless steel and corrosion-resistant materials. It is widely applied in industries that require clean production environments, stable performance, and high accuracy. With excellent anti-rust properties, it is suitable for humid and demanding manufacturing conditions.
Manufactured from premium stainless tool steel such as SUS420, SUS440, or customized grades, Stainless Punch Pin offers a balanced combination of hardness, toughness, and corrosion resistance. Through advanced CNC machining, precision grinding, EDM processing, and vacuum heat treatment, it achieves tight dimensional tolerances up to ±0.002 mm. This ensures stable punching accuracy and consistent performance during continuous production cycles.
Stainless Punch Pin is widely used in automotive components, electronics, medical devices, household appliances, connectors, and precision hardware manufacturing. It is suitable for progressive die systems and high-volume stamping applications that require long service life and stable quality output. Custom options including diameter, length, head design, and surface polishing treatments are available according to customer requirements. This flexibility makes Stainless Punch Pin a reliable solution for OEM tooling, non-standard parts, and precision metal forming applications across a wide range of industrial sectors.
