Fit for RIM Molding
We are often asked when is the Reaction Injection Molding process is well-suited for a low volume “life science” project. Here are a few tips that may help you discern when RIM molding may be your project solution.
- If the estimated annual usage is not significantly higher that 2500 EAU.
- RIM molding may be a viable solution as a bridge to high volume steel tooling. Engineering/design teams re-evaluate the EAU and realize it may take a few years to reach the anticipated volumes.
- RIM may not be your solution if your project requires a high volume EAU at product launch (ie. 5000 EAU).
- Parts with a flat configuration may be a fit for RIM molding if the parts are part of a molded assembly or could be part of an integrated geometry. Complex geometry can easily be molded using the RIM process, as the resins have the viscosity of skim milk which fills the mold completely.
- Small widget like parts will not be a fit for the RIM process. However small parts may be a fit if the parts are part of an assembly.
- Projects requiring precise fit-ups and tight tolerances may be we be a fit for Reaction injection Molding.
We welcome the opportunity to review your assemblies and may offer recommendations based on your geometry. It is recommended to submit a drawing or CAD file for engineering to take a look-see to evaluate specific project elements and its complexities to help determine if your project is well-suited for the “Reaction Injection Molding” process.
