1. Definition & Issues (The "Why")

Metal stamping and deep drawing dies are high-performance tools requiring extreme durability and precision. Buyers often face critical technical hurdles:

• Tearing During Deep Drawing: Caused by poor die profile design or inadequate surface finish of the punch/die, leading to excessive friction.

• Step Pitch Inaccuracy: In Progressive Dies, a cumulative error of even 0.01mm across multiple stages can result in non-conforming finished parts.

• Tool Premature Failure: Using inferior tool steel or improper heat treatment leads to rapid dulling or chipping of cutting edges.

Vina CNC eliminates these risks through metal flow simulation design and high-precision Wire EDM and CNC machining centers to guarantee micron-level tolerances.

2. Technical Classification (The "How")

• Progressive Die: Integrating multiple operations (blanking, bending, piercing) into one tool for high-volume mass production.

• Deep Drawing Mould: Specialized for forming cup-shaped or box-shaped components from sheet metal.

• Precision Machining: High-accuracy fabrication of mold plates, punch inserts, and guide components.

• Tool Steel Materials: Utilizing SKD11, DC53, and SKH51 with vacuum heat treatment for optimal hardness.

3. Technical Advantages (The "Proof")

• Precision: Maintaining strict positioning and pitch tolerances of ±0.005mm.

• Surface Integrity: Achieving mirror-finish integrity in deep drawing cavities to ensure smooth forming and flawless aesthetics.

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