这个过程从它的名字出现在工具中的化学反应。 所用的塑料是热固性材料，无论是聚氨酯或发泡聚氨酯。 产生聚氨酯的两种组分混合之前toinjection到工具中。 与低粘度和低的注射压力，大的，复杂的零件可以经济地在低量生产。

ReactionInjection成型（RIM ）生产零件的复杂细节， aredimensionally稳定，耐化学性，物理坚韧，耐磨的。 这个过程是对规模较大的塑料partsproduced在短期内或小批量量产的最佳选择。

• 优异的流动性使得成型复杂的几何形状，包括：天窗，肋骨，老板和开口

• 高级化妆品的外观明显的关键应用

• 精湛的封装能力

• 聚氨酯注塑件在2-5周

The process takes its name from a chemical reaction that occurs within the tool. The plastics used are thermosets, either polyurethanes or foamed polyurethanes. The two components that produce the polyurethane are mixed just prior toinjection into the tool. With the low viscosity and low injection pressures, large, complex parts can be produced economically in low quantities.

ReactionInjection Molding (RIM) produces parts with intricate detail that aredimensionally stable, chemically resistant, physically tough, and wearresistant. This process is an excellent choice for larger plastic partsproduced in short run or low volume production quantities.

• Excellent flow ability allows molding complex geometry including: louvers, ribs, bosses and openings

• Superior cosmetic appearance for visibly critical applications

• Superb encapsulation ability

• Polyurethane molded parts in 2-5 weeks
