RIM mold
From Plastics Wiki, free encyclopedia
RIM mold Molds for reaction injection molding may be constructed from epoxy, nickel aluminum, or steel, depending upon the expected life of the mold. They should be designed to constrain a foaming pressure of 30-50 psi. For molding with a dense outer skin, it is important to use a temperature-controlled metal mold.
