Reaction Injection Molding

What is Reaction Injection Molding (RIM)?

RIM is short for Reaction Injection Moulding it is a production method for low volume manufacturing. As they produce high-quality parts with a variety of different designs, sizes and material properties this manufacturing technique is well proven by our engineers. RIM has many benefits regarding technical details such as flexibility and cost-efficiency even though it is a production process that takes more time. It utilises low-viscosity polymers in several thermoset processes.

Moulding Process

After the contained polymers are injected into a heated mould a chemical reaction lets them expand which is how the RIM process begins. The surface of the mould forms the mechanical design of the printed product. After injection the part slowly cures inside the mould and eventually becomes rigid. The shape and physical details of the part determine the curing time. There are several low volume manufacturing techniques all of which our engineers are familiar with. For this reason they can precisely produce the part you requested regarding shape, density, material and weight. It is possible to manufacture a variety of solid polyurethane parts with RIM process.

Reaction Injection Moulding Explained

RIM is a method of mixing two reactive liquid ingredients and immediately injecting them into a mould cavity where the chemical reaction cures the object.

Advantages of Reaction Injection Moulding:

  • Flexibility in design, size and surface finish
  • RIM Polyurethane parts possess an internal foam structure surrounded by a dense outer layer
  • A variety of other materials are avilable such as epoxies and urea-formaldehyde
