Nitried Screw Barrel Single Screw Extruder Screw Barrel with Air Cooling or Water Cooling HRC 50-60 Durable and Precise Extrusion Component

The Single Screw Extruder Screw Barrel is a high-precision, durable component engineered specifically for plastic extrusion machinery. As an essential part of the Extrusion Screw and Barrel Set, it delivers optimal performance and longevity across a wide range of extrusion processes. Manufactured with a 1000mm barrel length and built to customer-specific drawings, this screw barrel provides a customized solution that aligns precisely with the requirements of individual extrusion systems.

The screw barrel achieves a hardness rating of HRC 50–60, ensuring excellent wear resistance and durability even under high-pressure and high-temperature operating conditions. This hardness level significantly reduces the risk of deformation and wear, extending equipment service life and minimizing downtime caused by maintenance or part replacement.

Beyond mechanical hardness, the extruder screw and barrel system undergoes a specialized nitriding process that raises surface hardness to HV 950–1100. Nitriding diffuses nitrogen into the steel surface, creating a hard, wear-resistant layer without compromising the core toughness of the barrel. This treatment improves resistance to corrosion and abrasion while helping the barrel maintain precise dimensional tolerances over prolonged use.

Cooling is a critical aspect of the design. To ensure optimal thermal management during extrusion, the barrel is equipped with either air cooling or water cooling systems, depending on application requirements. These options help maintain stable operating temperatures, prevent overheating, and support consistent material flow and melting—extending the life of the barrel and screw assembly while contributing to overall extruder efficiency.

The 1000mm barrel length offers an ideal balance between processing capacity and machine size, enabling efficient melting, mixing, and homogenizing of polymer material. Combined with the precision-crafted screw, this assembly ensures smooth material conveyance and uniform output quality. Design flexibility to accommodate customer drawings allows seamless integration into existing extruder machines or customized extrusion lines, serving industries such as plastics, rubber, and compounding.

Each component is manufactured from high-grade steel using state-of-the-art machining techniques and undergoes strict inspection and testing to guarantee dimensional accuracy, hardness, and surface finish. This meticulous process ensures consistent results, minimizes material waste, and supports high production throughput.
