Press molds [Precision mold design and parts processing examples] Improvement of carbide punch lifespan

The lifespan of punches has tripled thanks to milling technology for hard materials! Here is a case study for a precision electronic components manufacturer.
When machining hard materials using electrical discharge machining, microcracks caused by heat during processing occur. These cracks penetrate to a depth of about 20μm, and no matter how much you polish the surface, they remain.
These cracks can lead to wear, especially in punches subjected to high loads.
In contrast, milling does not produce any microcracks at all. Milling tools can go down to R0.1, offering very high flexibility in machining shapes.
[Case Overview]
- Customer Industry: Precision electronic components manufacturer
- Inquiry: Wanted to improve the lifespan of hard material rivet punches
- Proposed Solution: Transitioning from electrical discharge machining to milling
- Technology Used: Milling technology for hard materials
- Results: The lifespan of the punches has tripled
