RTM - Resin Transfer Molding
RTM is a manufacturing process, which uses closed molds and vacuum assist. Reinforcements are layed up according to the needed material strength. The matrix material is chosen according to the needs of the customer and case by case.
High surface quality can be easily achieved with RTM for example by gelcoating or by using a colourant. Production volume can be approximately from 500 to 5000 items annually. The installation of inserts is achievable during or after the molding process. It is also possible to use a core material during the injection or by producing it as an insert according to the shape of the component.
Exemplary products: various hatches, rail road signal lights, tractor roofs.
