What is Reaction Injection Molding?

Plastics - Reaction Injection Molding

The term RIM refers to Reaction Injection Molding. RIM is the ideal process for achieving a superior finish on high-quality, limited-run (200-2000 per year) custom enclosures and housings. Even when longer production runs are anticipated, many designers choose RIM because of the exceptional appearance of our parts - with the added benefit of lower initial tooling costs.

The RIM material can be molded with a wall thickness varying from .250" to .750" within the same part-without sink marks. It has a finished density of 35 to 45 pounds per cubic foot, and it meets industry standards for combustibility and impact resistance required on most consumer products (UL rating 94V-O, 94-5VA).

Design guidelines for designing plastic parts in RIM structural foam are quite similar to those that one would use in designing thermoplastic structural foam. One added benefit to using the RIM process is the absence of sink lines. Due to this fact, molding thick cross-sections next to thin ones is no longer an obstacle. In order to reduce your engineering time, we recommend that you contact us during the early phase of your design process so that we can assist you in answering any questions that you might encounter.
