CNC Parts - Stripper Plate

During the stamping process, the stripper plate of the hardware custom stamping die is used to separate stamped parts from scrap, ensuring the stability and efficiency of continuous production.

Pain Points:
– Insufficient Machining Accuracy: The clearance tolerance of the stripper plate is ＞±0.02mm, resulting in a scrap carry-over rate of 0.5%, which requires manual intervention.
– Edge Wear Failure: Under high-frequency impacts, edge wear causes fluctuations in unloading force of ±15%, leading to part scratches or die jams.

Solutions:
Precision Machining: Use precision wire cutting (Accuracy ±0.002mm) to process the edges, ensuring clearance consistency.
Material Upgrade: Choose SLD alloy steel (JIS standard, vacuum quenching and tempering to HRC60±1), reducing wear by 67% compared to SKD11.

Final Effects:
Yield Improvement: The scrap carry-over rate decreases to 0.1%, and the finished product yield increases from 98.5% to 99.9%.
Lifespan Extension: The service life increases from 9 months to 18 months.
Maintenance Costs: Overall cost savings of 25%.
