Reaction Injection Molding (RIM)

Fabrifi™ specializes in the Reaction Injection Molding process. RIM molding materials range from soft and flexible to high impact structural rigid. Aesthetic features consist of integral color, and surface treatments including cap material, custom textured integral skin, or an in-mold coating.

Reaction Injection Molding (RIM) is the process of mixing two liquid reactants using high pressure impingement to form a thermoset polyurethane polymer. These polymers can be structural or flexible depending on the chemistry used to develop them. Process advantages include:

  • Small to large complex parts
  • Cost effective tooling
  • Mechanical toughness
  • Wear resistance
  • Environmental resistance
  • Chemical resistance
  • Dimensional stability
  • Rigid, soft, or a combination
  • Various surface treatments
