Reaction Injection Molding (RIM): Benefits
The thermosets employed in reaction injection molding create polymer chains that act as strengthening backbones in the molded product, providing excellent properties in extreme temperatures.
Furthermore, RIM molding is suitable for a wide range of thermosets, from structural foams to elastomeric polymers and high-impact and corrosion-resistant polydicyclopentadiene (pDCPD). Osborne has PhD chemists on staff that can help formulate resins to meet specific customer requirements. This means Osborne is not restricted to molding “off-the-shelf” resin formulations.

The low processing temperatures and injection pressures allowed in reaction injection molding mean the tooling investment is often more cost-effective for large parts when compared to injection molding tooling.
RIM’s other cost-saving advantages include:
| Varying wall thickness |
| Better economies for lower volume parts compared to injection molding |
|
| Enables part consolidation when compared to sheet metal |
| Tooling that’s usually less expensive than that for injection molding |
| Lower labor requirements than resin transfer molding |
| Lower energy usage and less need for floor space than injection molding |
Altogether, these advantages make reaction injection molding the economical choice, especially for runs of thousands of parts.
