Profile Grinding Challenges in Connector Progressive Dies
In modern connector manufacturing, progressive stamping dies often operate at extremely high speeds — commonly 200 to 400 strokes per minute. At these speeds, punch performance becomes a critical factor in maintaining…
Case Study: Improving Punch Life at 280 SPM Through Edge Radius Control
At high stamping speeds, punch failure is rarely caused by dimension error alone. In this case study, we share how controlled edge radius — not tighter tolerance — improved punch life significantly…
Tungsten Carbide Punches vs Tool Steel Punches
In precision metal stamping, punch materials impact tool life, stamping stability, maintenance cost and overall production efficiency. Tungsten carbide punches and tool steel punches are widely used. In this article, we will…
