19. The stripper must have a minimum of .250" clearance from bottoming on the heel blocks when the die is at shut height.
20. Install a shedder pin in the stripper at the cut off to prevent the part from sticking to the stripper, plus include shedder pins in areas of extended pilots.
21. Draw applications must have a binder or pad designed into it so the metal flow can be controlled using a secondary power source such as springs, gas cylinders, or air cushion.
22. All stripper retainers must be removable from the working surface of the die.
23. Hardened backing plates are required under all pads that bottom out.
24. No work should be done with the stripper unless it is unavoidable. All strippers with form inserts, pads, and lance/pierce details must be guided by pins and bushings and must bottom out on balancing blocks. All inserts are to be hardened.
