摘要

Reaction injection molding (RIM) involves mixing and injection of two reactants into a mold followed by a rapid, highly exothermic polymerization. Large parts can be ejected in less than 30 seconds and center exotherms of over 100 degree C have been measured. Present commercial equipment uses thick wall steel cavities with water cooling/heating. Mold heat transfer has been modeled as unsteady conduction from a thin slab with heat generation. Strictly, the boundary condition is also dynamic with the metal wall as an unsteady slab with convective heat transfer to turbulent water on one side. This coupled heat transfer problem has been solved numerically. A laboratory size RIM machine was constructed with an instrumented slab mold. Preliminary measurements of temperature profiles compare well to model predictions.
