Sheet Lifter Dies

Lifter dies are placed in your turret press on each side of a special forming tool. When the sheet passes through this section of the turret, these lifter dies will lift the sheet up to the height of the form die preventing the sheet from colliding with the forming die, which at times, can cause the sheet to break the grip of the work holder clamps.

Progressive tools are made to exact material thickness, were standard louvers can punch a range of material thickness.  Progressive louver must have gentle radius slope on end, were standard louver can be tight radius.
