Reaction Injection Moulding (RIM)

What is Reaction Injection Moulding (RIM)?

Reaction Injection Moulding is a production method for low-volume manufacturing. As they produce high-quality parts with various 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 a production process takes more time. It utilises low-viscosity polymers in several thermoset processes.

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 various solid polyurethane parts with the RIM process.

Reaction Injection Moulding Explained

RIM (Reaction Injection Moulding) is a highly efficient manufacturing method that involves blending two reactive liquid ingredients and rapidly injecting them into a mould cavity, where the resulting chemical reaction cures and solidifies the object. RIM is commonly used in the production of various plastic parts and components for a wide range of applications, including automotive, aerospace, and medical devices.

One of the key advantages of RIM is its ability to produce complex shapes and intricate designs with precision and accuracy. Additionally, RIM parts tend to have excellent physical properties, such as high strength-to-weight ratios, durability, and chemical resistance. These properties make RIM an ideal choice for producing lightweight yet sturdy components for demanding applications.

Overall, RIM is a cost-effective and versatile manufacturing process that offers many benefits over traditional methods. Whether you need to produce high-quality plastic parts quickly and efficiently or create complex designs with intricate details, RIM is a reliable and effective solution that can meet your manufacturing needs.
