Stripping material is a
crucial part of the punching process. The video on the left shows the standard
stripper assembly on the Piranha P-50 ironworker. The yellow base is the
stripper foot and the black tubes on either side of the punch are the urethane
strippers. When released the urethanes press down on the stripper foot. The
stripper foot then strips the material off the punch.
The photos on the right
show the different urethane strippers we stock. Unlike the black Piranha
strippers, the red and blue strippers slide over the punch to strip the
material. The colors signify different hardness/durometer of urethane. The
harder urethane (red) is used for thicker material, while the softer urethane
(blue) is used for thinner material. It’s important to use the correct urethane
to ensure the material will not distort while stripping. When the urethane starts
to crack, it is time to be replaced. This helps ensure quality holes and
extended tool life.
