In contrast to thermoplastics, where a molten plastic is compacted in a mold and then solidifies upon cooling, Reaction Injection Molding systems are composed of liquid components that chemically react to form plastic material in a mold. The RIM process uses less expensive molds, less energy, and lower-tonnage presses than thermoplastic processing. These characteristics provide design, economic, and processing flexibility. A major benefit of Reaction Injection Molding versus thermoplastic production is the cost of the tooling. Since RIM mold pressures are significantly lower, Reaction Injection Molding molds are typically made from aluminum which is not only less expensive but also less costly to machine. Typically, a RIM mold is one half the cost of a comparable thermoplastic mold. This becomes particularly important where the part volume is low. In addition, the lead time for a RIM mold can be significantly shorter than for a thermoplastic mold. |
