RIM Question What is RIM? How is RIM different than regular injection molding? How many kinds of RIM are there? What are the major RIM materials? How would I know if my part is right for RIM? What finishes are available?

What is RIM? Reaction Injection Molding (RIM) is a unique molding method where two chemicals are mixed immediately before injection into a mold. Therefore, the exothermic reaction takes place in the mold as the chemical bonds form polyurethane. In a few minutes it hardens, heat exchangers help cool the mold, and out comes a part.                         © 2008 Rimnetics, Inc.   Mountain View & Loomis, California | Rimnetics is ISO 9001:2000 Certified
