RIM Manufacturing, LLC
RIM Manufacturing, LLC has grown to be one of the largest independently owned plants in the country specializing in custom Reaction Injection Molding
The chemical reaction that distinguishes Reaction Injection Molding from typical injection molding makes all the difference in how your products perform. RIM Manufacturers use low viscosity liquid polymers which expand and harden in the mold at much lower temperatures than those of plastic injection molding or thermoforming. Additionally, your RIM designs can be much more intricate with a greater range of weight, strength, density, and hardness.
Every member of RIM Manufacturing is dedicated to making our clients successful in each phase of the production process – part and CAD design, mold design and manufacturing, part production, secondary processing, painting and silk screening, assembly, packaging, and shipping.

Since these liquid polymers require less pressure (~100 psi) and lower temperatures (~90°) than typical ingredients, they can be injected into cost-efficient aluminum molds, lowering tooling costs. The molds are then moderately heated (~190°), but the resulting exothermic reaction quickly brings the materials to (~325°) and promptly cures the part inside the mold.
