Resin Transfer Molding
RTM is used to mold components with complex shapes, large surface areas and a smooth Finish on both sides for applications like truck cabs and electrical cabinets.
This process consists of injecting a thermosetting Resin into a closed mold cavity. Continuous Filament mats, complexes or fabrics can be used in RTM as reinforcement. The resin wets through the reinforcement and solidifies to form a Composite part. Molding pressure is lower than in the compression molding process, so tooling and equipment capital costs are lower than high-volume compression molding, but higher than open molding processes.
