Reaction Injection Molding

What is Reaction Injection Molding (RIM)?

Reaction Injection Molding is a production method of low-volume manufacturing. Our engineers are highly favouring this manufacturing technique, because they produce high-quality parts with a wide range of designs, different sizes and overall superiority. RIM is a longer production process, but it has many benefits regarding technical details, flexibility and cost-efficiency. It utilizes low-viscosity polymers in several thermoset processes.

The process of Reaction Injection Molding?

The process of RIM starts with a chemical reaction that lets the contained polymers expand after they are injected into a heated mold. While the surface of the mold is forming the mechanical design of the printed product. After injection, the part slowly cures inside of the mold and becomes rigid. The curing time varies depending on the part’s shape and physical details. Our engineers are familiar with several different low-volume manufacturing techniques. Therefore, they are able to precisely deliver your requested part regarding shape, density, material and weight. RIM can be chosen to produce a wide range of flexible, elastomeric or solid polyurethane parts.

Reaction Injection Moulding easily explained:

Two reactive liquid ingredients are mixed and immediately injected into a mould cavity
where the chemical reaction is curing the object.

Advantages of Reaction Injection Molding

  • Flexibility in design, size and surface finish
  • RIM Polyurethane parts possess an internal foam structure surrounded by a dense outer layer
  • Wide range of other materials: epoxies, urea-formaldehyde
