Resin transfer moulding

Resin transfer moulding (RTM) is a manufacturing process that uses resinous materials to create composite parts. RTM is commonly used in the windmill industry and the hydro energy industry, as it is well-suited for creating large, strong, and lightweight components.

RTM is a manufacturing process that can be used to produce composite components with high dimensional accuracy and repeatability.

 RTM is typically used for parts that require a high degree of detail or where the surface finish is critical. The process begins with the placement of reinforcing fibers onto a mould and involves injecting resin into a mould that contains the desired shape of the part. The resin is then cured, typically using heat and pressure, to form the final shape of the component. RTM is well suited to the production of parts with complex geometry, and it can be used to produce parts with either smooth or textured surfaces.

MM Composite specializes in RTM composite components, and we are proud to be one of the leading suppliers in this field. Our team has extensive experience in RTM manufacturing, and we are always striving to innovate and improve our process.

“When I had to have recreated a rear spoiler in carbon fiber to my Corvette race car, I contacted MM Composite, which immediately had a dedicated team available. The original drawings were missing, but that was not a challenge for the team that performed the task to perfection. Besides the high quality of the product, I also got the design counselling and and sparring with the finished product.”
