Plastics materials are plasticised in an extruder with barrel and at least one revolving screw inside, whereby the material is fed into the barrel and conveyed to a suitable tool whilst the material is heated by h/f during operations. The heating is provided in certain limited parts where no friction is produced by the interaction of screw and barrel.
