Stripper Plate
The plate that strips the material off the punches after the cutting stroke.
What it means on the floor
As punches retract, the stock tends to cling to them. The stripper plate holds the strip down and pulls it free of the punches. Strippers can be fixed or spring-loaded (travelling), and spring strippers also guide the punches and hold the material flat during cutting.
Sizing stripper springs requires estimating the stripping force, which scales with the cut perimeter and material thickness.

Applying the term
Interpret Stripper Plate in the context of the drawing, governing standard, and customer requirement in front of you — the same word can carry different limits in design, quality, and production documents. Check whether a stated value is nominal, minimum, maximum, or reference-only, and whether it applies before forming, after forming, or after heat treatment.
