CNC Parts - Stamping Die Punch Retainer Plate

The stamping die components – punch retainer plate forms a sliding fit with the custom metal punches through the precision holes, providing rigid support during the stamping process to prevent displacement.

Customer Pain Points:
1. Wear: Due to high-frequency stamping operations, micro-chipping occurs at the edges of the guide holes, resulting in a short lifespan.
2. Accuracy: The accuracy of the punch holes is >0.01, leading to micro-motion wear and excessive burrs on the stamped parts.

Solutions:
* Heat Treatment: Use DC53 material, with vacuum hardening and triple tempering, achieving a stable hardness of HRC60-62 to enhance wear resistance.
* Machining: Use slow wire cutting with precision controlled within ±0.005 and surface roughness Ra ≤ 0.8.

Final Results:
Lifespan increased by 50%.
Stamping yield improved to 99.1%.
Overall production efficiency increased by 30%.
