Reaction Injection Molding (RIM) is a low pressure, low temperature process used to mold many types of strong, lightweight plastic parts that are easily painted. This process is typically used for the medical, industrial and automotive industries. When you work with SUPERIOR, your project starts with a review of your CAD files or design drawings, to ensure that your plastic enclosures can be produced via the RIM process. This DFM (design for manufacturing) review gives us the chance to suggest adjustments to improve the manufacturability and function of your plastic enclosure, while keeping tooling and part prices down.

Products created from RIM are typically more economical than other molding methods, especially for larger parts. In general, RIM uses less energy and equipment to make the same product when compared to thermoplastics.

Our advantages:

RIM molding allows for many distinct advantages, some of which include:

• Large Parts - The properties of the liquid polyurethane components enable them to fill molds for very large parts, maximum pouring size: 2000mm*1200mm*1000mm. 
• Encapsulation of Inserts - Inserts of many types can be placed into a mold prior to injection of the RIM material. The RIM material can also encapsulate many inserts during molding.
• Thick and Thin Walls - The RIM process offers you the flexibility to design parts with significant wall thickness variations.
• Class - A Surfaces - The surface finish of parts molded with the RIM process allows manufacturers to produce Class a painted parts.
• Low Cost Tooling Options - The low injection pressures of the RIM process allow for tooling to be manufactured quicker, and at lower cost, than tools used in traditional injection molding, or structural foam.
