One-Shot Molding

A urethane foam molding process in which the reactants, usually an isocyanate, a polyol and catalyst, are fed in separate streams to a mixing head from which the mixed reactants are discharged into a mold.  The polyol and catalyst are sometimes combined along with other additives, but the isocyanate is always fed separately to the mixing head.
