Wood Compounder

The Wood Compounder is a Twin Screw Compounder for the production of Wood-Plastic-Composites or other natural fibres and paper to pellets or by direct extrusion to profiles.


  • Fiber/Plastic mixture 50:50 to 80:20 as needed for the application
  • Using of non pre-dried wood or other natural fibres by using a patented technology.
Compounding line for the production of Wood Plastic Composites pellets

Processing steps:


  • gravimetric feeding of all components
  • drying of the fibres in the main Compounder
  • adding the fibres into the plastic melt (e.g. PP, PE, PVC etc.)
  • mixing and homogenising of the plastic with the fibres at low temperature
  • discharge the product via a single screw discharge extruder to a hot face pelletiser or via a special die
    to profiles.
  • production of pellets or direct
    extrusion to profiles


WPC pellets can be used for extrusion, injection moulding and for the production of sheets by a bandpress technology or by a transfer injection press.


In cooperation with our partner, we are also able to offer special injection moulds for WPC.
