Most people know about injection molding, but what some don’t know is that there may be a better, more cost effective option that delivers a superior polyurethane product – Reaction Injection Molding (RIM). And when it comes to RIM, no one has more experience and more expertise than RIM Manufacturing.

Since 1979, RIM Manufacturing, LLC has specialized in Custom Reaction Injection Molding (RIM Molding) and is one of the largest independently owned plants in the country. Located near Dallas/Ft. Worth, our current facility resides on over three acres with more than 32,000 square feet of operating plant floor space. Over the years, RIM Manufacturing has grown significantly in size and capability and is also ISO 9001:2008 Certified for RIM Molding and Electro-Mechanical Assembly.

RIM Molding Process

Unlike thermoplastic injection molding, Reaction Injection Molding is a process capable of achieving a broad range of properties. Depending on the formulation of the polyurethane RIM system, the parts molded can be a foam or a solid and can vary from flexible to extremely rigid.  Additionally, molded parts can be extremely large and very light weight with walls thickness easily varied.

RIM Advantages 

There are significant advantages to using RIM Molding over other processes, including: holding tight tolerances; encapsulation of a variety of materials such as metal, wood, electronic circuitry, etc.; varied wall thicknesses without sink marks; decorative design; design flexibility; part durability; part flexibility; low cost tooling; and other advantages.
