Advantages of urethane springs, open end strippers and tubes:
- High pressures
- Closer center distances
- High tear resistance
- Oil resistant
- Punch vibration dampening
- Easy installation and replacement - No need for set screws or stripper bolts
- No shrapnel (flying to pieces, when fractured under load) thus preventing injury to worker and damage to the die.
- Conventional heavy duty die springs obtain up to 500 lbs. per 1/8" deflection, compared to 2600 lbs. per 1/8" deflection on urethane springs.
