RTM, RIM and Filament Winding

Intelligent solutions by DOPAG

There are three different manufacturing processes involved in the production of fibre-reinforced plastics: Resin Transfer Moulding (RTM), Reaction Injection Moulding (RIM) and Filament Winding.

  • RTM and RIM
    There are a number of plural component resins used with the RTM and RIM methods, including, for example Polyurthane, Epoxy Resin, Acrylic Resin, Vinyl Ester Epoxy Resin or Unsaturated Polyester.
    These resins are processed by the use of a metering and mixing machine that applies the mixed material into open or closed moulds. The moulds are prepared with layers of fibres or pre-forms and/ or pre-wovens which are then impregnated by the mixed material. Once the application of the resins is completed the mould is closed to allow for curing, following which the part can be removed from the mould.
  • Winding technique
    In the case of the winding technique, the glass and carbon fibres pass through an impregnation bath after which it is wound onto a winding spindle.
