Bimetallic PTA screws

The screws are welded using the PTA process (plasma transferred arc) or an advanced laser method. Bimetallic screws are ideal for productions where long screw life is needed and where higher wear level occurs due to the influece of abrasive ingredients. Especially suitable for extruder screws for plastics recycling, rubber screws and screws that manufacture products with recyclate additives. Bimetallic screws are not suitable for processing materials filled with glass fibre.
