High-Precision Tungsten Carbide Punch Pins with Micron-Level Precision, Superior Impact Resistance, and Tailor-Made Geometry for Cold Heading
In the pursuit of extreme efficiency and precision within cold heading processes, tool durability directly dictates production costs. Henghui Precision offers custom-engineered Tungsten Carbide (Cemented Carbide) Cold Heading Punches and Special-Shaped Non-Standard Dies, specifically designed to withstand high-strength impact and complex geometries. By combining world-leading tungsten carbide grades with micron-level CNC machining, we provide the automotive, fastener, and aerospace industries with high-performance tooling built for an extended service life.

Key Features
  • Premium Material Grade: We offer a wide range of high-quality tungsten carbide grades tailored to your specific working conditions (considering pressure, impact force, and material ductility). This ensures the dies maintain exceptional dimensional stability even under extreme operational pressure.
  • Micron-Level Precision: Leveraging advanced CNC grinding and EDM (Electrical Discharge Machining) technologies, our non-standard special-shaped punches achieve stable tolerances within 0.01mm, making them ideal for the mass production of high-precision components.
  • Superior Impact Resistance: By optimizing the tungsten carbide grain size and cobalt content ratio, our punches possess excellent toughness, effectively preventing chipping and premature cracking during high-speed production.
  • Tailor-Made Geometry: We specialize in "non-standard" designs. Whether it is a multi-station special-shaped punch or a forming die with complex steps and concave features, we provide exact 1:1 replication based on your 2D/3D drawings (STEP, DXF, or PDF).
  • Advanced Surface Finish: We offer professional mirror polishing (Ra < 0.1) and optional PVD coatings (such as TiN, TiCN, and TiAlN). These treatments further reduce the friction coefficient, enhance de-molding efficiency, and can extend the tool's lifespan by 3 to 5 times.

Typical Applications
  • Automotive Industry: High-strength engine bolts, special-shaped pins, and steering system components.
  • Precision Fasteners: Non-standard socket head cap screws, Torx head bolts, and specialized stepped screws.
  • Electronics & Aerospace: High-precision, micro-sized cold heading components that require extremely strict material integrity.
