Injection molding is a common process for many polyurethane products. Examples of the various markets that use polyurethane injection molding are: integral skin, rigid, back foam, shoe soles, office furniture and automotive interiors from arm rests to sound insulation. In many applications the mold release agent is applied to the mold, and then a paint coating is applied over the mold release agent. The mold will then be closed and the injection will take place. The final product will be removed fully painted.
