1. Definition & Issues (The "Why")

The Cold Heading Fastener Mold is the core of high-volume fastener production. To achieve Superior quality, the mold must withstand immense pressure without failure. Manufacturers often face these hurdles:

• Die Cracking: Internal stress or improper carbide grade selection leads to sudden failure during high-speed operation.

• Poor Surface Finish: Rough die cavities cause galling or scratches on the fasteners, complicating the subsequent plating process.

• Short Tool Life: High friction leads to rapid dimensional drift, requiring frequent and costly tool replacements.

Vina CNC eliminates these risks using high-precision shrink-fit technology and premium Tungsten Carbide inserts combined with mirror-finish polishing.

2. Technical Classification (The "How")

• Main Dies: Steel-encased Carbide inserts engineered for maximum compressive strength and impact resistance.

• Header Punches: Specialized punches for forming intricate head styles (Torx, Phillips, Hexagon, and custom profiles).

• Premium Materials: Micro-grain Tungsten Carbide (Grades G5, G6, etc.) and H13/SKD61 vacuum-heat-treated steel casings.

• Advanced Machining: Utilizing Wire EDM and Coordinate Grinding to ensure micron-level accuracy in the die cavity.

3. Technical Advantages (The "Proof")

• Precision: Maintaining strict cavity tolerances of ±0.002mm to ±0.005mm.

• Operational Performance: Engineered for stability at high speeds (200-400 pieces per minute).

• Metrology: 100% verification using digital profile projectors and 3D CMM dimensional check.
