Reaction injection moulding is a manufacturing process that offers a number of benefits. It is well-suited for the production of a wide range of parts, including large, complex parts with varying wall thicknesses. The process is also relatively fast and very energy efficient, making it a good choice for high-volume production, while in return having a positive impact on the environment.
What even is reaction injection moulding?
Reaction injection moulding (RIM) is a manufacturing process that uses two liquid components to create a solid, thermoset polymer. The two components are mixed together in either a low-pressure or high-pressure mixing machine before being injected into the mould, once the mixed material is in the mould an exothermic reaction takes place which causes the material to cure and solidify. It is a versatile process that can be used to create a wide range of parts, including Medical device enclosures, Instrument housings, solar panel cases, EV charger casework, automotive parts, furniture components, sporting goods, and industrial components.
What are the benefits of reaction injection moulding?
RIM offers a number of benefits over other manufacturing processes, including:
Low tooling costs: RIM tooling is typically made of composite resin or aluminium, which is less expensive than steel tooling used in other high volume moulding processes. This can save businesses a significant amount of money on the upfront costs of getting product into production.
Fast cycle times: RIM parts can be cured in minutes, which can help businesses to reduce lead times and increase productivity.
Wide range of materials: RIM can be used to create a wide range of materials, including solid resin, rigid foams, elastomers, and solid plastics. This versatility makes RIM a good choice for a variety of applications.
Excellent dimensional accuracy: RIM parts are typically very accurate, which is important for applications where tight tolerances are required.
Smooth surface finish: RIM parts have a smooth surface finish that is suitable for painting or other finishing processes.
Good environmental impact: RIM is a relatively environmentally friendly process, as it uses no solvents and doesn’t create harmful emissions. Composite Resin mould tools do not require heating or cooling which has energy saving benefits as well.
Flexible production capabilities: RIM can be used to produce parts in a wide range of sizes and shapes, making it a good choice for both large and small products.
What can reaction injection moulding be used for?
RIM can be used to create a wide range of parts, including:
Medical & Analytical Device Enclosures: RIM is often used to create complex casework, multi part enclosures (up to 30 parts making a single enclosure) are possible due to the accuracy and consistency of the mouldings. RIM parts are strong and durable, and they can withstand the harsh conditions of the laboratory environment.
Automotive parts: RIM is often used to create automotive parts, such as bumpers, spoilers, and fenders. RIM parts are strong and durable, and they can withstand the harsh conditions of the automotive environment.
Furniture components: RIM is also used to create furniture components, such as seats, armrests, and headboards. RIM parts are comfortable and durable, and they can be easily customized to match the design of any furniture.
Medical devices: RIM is used to create a variety of medical devices, such as prosthetics and implants. RIM parts are biocompatible and can be sterilized, making them ideal for use in medical applications.
Sporting goods: RIM is used to create a variety of sporting goods, such as golf clubs, tennis rackets, and kayaks. RIM parts are strong and lightweight, making them ideal for use in sports.
Industrial components: RIM is used to create a variety of industrial components, such as pumps, valves, and housings. RIM parts are durable and can withstand the harsh conditions of industrial environments.
