TiN Coated Tungsten Carbide Upper Mold Insert | Cold Heading Die for Nut & Bolt Forming

TiN Coated Tungsten Carbide Upper Mold Insert – Cold Heading Die

HengfaMold's precision tungsten carbide upper mold inserts feature a Titanium Nitride (TiN) PVD coating, engineered for high-volume nut and bolt cold heading operations. The gold yellow TiN layer reduces friction, improves part surface finish, minimizes material adhesion, and significantly extends tool life in demanding fastener manufacturing environments.

Key Features

• TiN PVD coating (gold yellow) – reduces friction, prevents material adhesion, extends insert life
• Tungsten carbide substrate – superior hardness and compressive strength for cold heading
• High surface finish – improved part quality and reduced ejection force
• Tight dimensional tolerances – consistent forming accuracy across high-volume production runs
• OEM & custom sizes available – drawing-based manufacturing supported

Applications

Suitable as upper mold inserts for cold heading machines producing nuts, bolts, screws, and other fasteners across automotive, construction, electronics, and industrial sectors.
