There are a variety of ways to reduce the required press tonnage. Use Tonnage Compensator Caps – Stagger the punch length so that the punches pierce the material at different intervals Add Punch Shear  – A shear angle ground onto the punch tip reduces the load or tonnage unlike flat faced punches Use correct die clearance – This […]Read More

Proper clearance between the punch and die is essential for piercing a well-made hole efficiently. Too much punch and die clearance results in more rollover deformation where the punch enters the material and a large burr on the die side. With proper clearance between the punch and die, there will be minimal rollover deformation around the […]Read More
