How Carbide Punches Improve Terminal Stamping Quality

Introduction

Electrical terminals require extremely precise stamping of thin copper alloy. Tungsten carbide punches ensure the accuracy and consistency terminal production demands.

Sharp Edge Retention

Carbide punches maintain sharp edges through millions of strokes. This produces clean, burr-free terminal features that ensure proper electrical contact and assembly fit.

Dimensional Accuracy

Because carbide wears slowly, terminal dimensions stay consistent throughout production. This eliminates scrap from drifting punch dimensions and ensures interchangeability.

Polished Surfaces

Polished carbide punch surfaces prevent copper pickup and scratching. This produces smooth terminal surfaces that slide easily into connectors and housings.

High-Speed Production

Carbide rigidity supports the high stroke rates required in terminal stamping. The material resists deflection and fatigue, maintaining precision at high speeds.

Conclusion

Carbide punches are essential for terminal stamping. Their precision, sharp edges, and long life ensure high-quality connectors in high-volume production.
