SCREW-BARREL

Bimetal and nitrided screw and barrel systems used in plastic injection molding and extrusion machines are manufactured from special alloy steels with high wear and corrosion resistance. The nitriding process increases surface hardness and extends service life, while the bimetal lining provides maximum performance when processing glass-filled, mineral-filled, and highly abrasive materials. Technical Specifications: * High wear and corrosion resistance * Nitriding hardness: 900-1100 HV * Nitriding depth: 0.4 – 0.8 mm * Bimetal alloy hardness: 58-65 HRC * Precision-ground inner surfaces * Long service life and high efficiency * Suitable for injection molding and extrusion applications
