1. Definition & Issues (The "Why")

Punches and Dies are high-stress components designed to withstand constant impact and friction. Buyers often encounter critical hurdles:

• Short Tool Life: Inferior steel grades or improper heat treatment lead to chipping and premature wear, causing costly downtime.

• Poor Surface Integrity: Leading to material galling or excessive burrs on stamped parts, compromising final product quality.

• Tolerance Stack-up: Even a few microns of misalignment between the punch and die can result in catastrophic tool failure.

Vina CNC eliminates these risks by utilizing high-precision Coordinate Grinding and Wire EDM technology, combined with premium imported tool steels (SKD11, DC53, M2, Carbide).

2. Technical Classification (The "How")

• Punch & Die Customization: Manufacturing of round, rectangular, and complex profile punches based on strict CAD specifications.

• Precision Mould Parts: Production of Ejector pins, Mould cores, Guide bushes, and specialized inserts.

• Hard Material Machining: Specialized in processing hardened tool steels (60-62 HRC) and Tungsten Carbide.

• Advanced Coatings: TiN, TiCN, or DLC coatings to enhance surface hardness and reduce friction, extending tool life by 200-300%.

3. Technical Advantages (The "Proof")

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

• Surface Finish: Achieving mirror-finish integrity to ensure smooth part ejection and minimize burrs.

• Metrology: 100% verification using Profile Projectors and 3D CMM dimensional check.
