Safe, Reliable Tools for Mold Release
Fabricators use plastic release wedges to help remove medium-to-large parts from a mold. Wedges are inserted around the perimeter of the mold, between the mold and the part, and then gently driven in until the piece pops out. It is necessary to use a sufficient number of wedges at the perimeter, particularly for larger parts—one wedge will not do the job. Each wedge should be tapped, in turn, as you progress around the mold.
Wedges are made of soft polyethylene, so as to not damage the mold or the part. White wedges are more rigid in nature, the pink are slightly more flexible.
