In the context of the current debates about carbon emissions and lightweight construction, KraussMaffei Technologies GmbH, Munich, Germany, has pushed ahead with the development of high-pressure resin transfer molding (HD-RTM) in recent years, with the aim of producing fiber-reinforced parts in large quantities. High-pressure injection permits highly reactive resin systems to be processed. This reduces cycle times significantly compared to conventional RTM processes.

The HD-RTM variants by KraussMaffei presented here cover different parts and process requirements. With C-RTM, the relatively low cavity pressure reduces the investment costs for the press. Wet molding permits recycled fibers to be processed, leading to more efficient material usage. Parts produced by the T-RTM process consist of a thermoplastic matrix, and can therefore, e.g., be recycled or welded if necessary. The surface RTM process produces paintable surfaces and is particularly suitable for the production of visible fiber-reinforced components.

The variants presented here are used in a wide variety of industries and applications. Over 80 HD-RTM machines by KraussMaffei are currently in use around the world.
