Method for extruding a mixture

It will etc. described a first thermoplastic and of a second thermoplastic to a method of extruding a mixture of granules, grit or powder, the melting range of the first thermoplastic the melting range of the second thermoplastic deviates, with an extruder, of a heatable housing and a screw having which a feed zone, a melting zone, a metering zone and a be having from the feed zone to the discharge zone extending bore, in which a temperature control medium is introduced, wherein the temperature control heating of the screw in the feed zone to a temperature below the melting range of the thermoplastics causes the lower melting range and a temperature of the screw in the discharge zone at a temperature which is between the melting range of the first and second thermoplastics.
