  • the extruder 4 is operated in a so-called "master batch operation" or is designed for such an operation. Because for proper and smooth operation of the extruder it is useful if the extruder used in the individual case is designed for a very specific mixing ratio between wood particles and plastic particles, since the mixing ratio determines the strength of the added paste mixture to a very considerable extent. This means that a mixing ratio that is always matched to the extruder used is first generated in the mixing device.
