Reaction Injection Molding

Reaction Injection Molding (RIM)

A Leader in Reaction Injection Molding


Reaction Injection Molding (RIM) is what we do. From luxurious, soft-touch interior components to durable, high-impact exterior components, AdvancTEK’s five unique RIM systems are tunable for most polyurethane composite applications. With expansive RIM experience, we have partnered with a wide range of industries to help them bring their RIM project to reality.

What is Reaction Injection Molding?


Reaction Injection Molding

Two components are mixed together, injected under high pressure into a mold, the polymer expands to fill the cavity of the mold, and cures to create a finished product designed for use in a wide range of applications. Material characteristics can be custom-tuned for a wide range of applications. RIM offers much of the same design flexibility as injection molding, but it requires significantly less tooling investment.

Advantages of RIM

Advantages of Reaction Injection Molding

  • Excellent Acoustic Properties
  • Excellent Thermal Properties
  • Tunable (Density & Thickness)
  • B-Side Features & Insert Encapsulation
  • Lower Tooling Investment than Injection Molding
  • Endlessly tunable chemistry:  Soft-touch to rigid, high-impact characteristics
