Product Overview

Accelerate your fastener manufacturing and cold-forging production cycles with our high-impact Tungsten Carbide Cold Heading Die Inserts. Explicitly engineered to withstand severe, high-frequency repetitive axial impacts and intense radial expansion stresses, these premium cemented carbide pellets (nibs) serve as the heavy-duty wear cores inside multi-station cold heading steel mold housings.

Available as precision-sintered or semi-finished blanks equipped with centered pre-formed pilot holes, these carbide inserts allow for straightforward wire-EDM customization, final sizing, and diamond polishing. They provide unbeatable dimensional preservation for high-volume manufacturing of high-tensile bolts, nuts, rivets, and screws.

Technical Specifications & Standard Ranges

We supply a comprehensive dimension matrix to fit global headers, piece-formers, and progressive nut formers:

Target Applications & Machinery

Our rugged carbide cold heading cores are highly recommended for tooling setups in:

• Fastener Production: Cold heading dies for automotive-grade bolts (12.9, 10.9, 8.8), heavy-duty structural rivets, aircraft pins, and industrial nuts.

• Metal Cold Forging: Punching, extruding, and progressive stamping dies for producing universal joints, ball studs, and miniature copper electronic terminals.

• Steel Wire Processing: High-pressure sizing dies and progressive cold extrusion sleeves.

Full OEM/ODM Customization Capabilities

As a direct factory supplier, we offer fully tailored compositions and geometries aligned with your operational blueprints:

• Specialized Profiles: Beyond standard cylindrical pellets, we produce stepped outer profiles and complex internal multi-stage geometries based on drawings.

• Application Optimization: Provide us with your machine station setup, wire material diameter, and working speed, and our engineering team will calculate the ideal cobalt ratio to maximize tool life.
