Hardness HV950-1100 Parallel Twin Screws and Barrels Equipped with Air Cooling Providing Performance in Plastic Extrusion Processes

The Parallel Twin Screw and Barrel is a high-performance component engineered to meet the demanding requirements of industrial extrusion processes. Built with precision and durability in mind, it delivers exceptional reliability and efficiency for manufacturers seeking superior extrusion solutions. The dual parallel screw and barrel design ensures optimal material processing, improved mixing capabilities, and enhanced throughput, contributing to a more efficient production line.

The screws are manufactured from premium 38CrMoAlA alloy, renowned for its outstanding mechanical properties, including high strength and wear resistance. This material choice provides remarkable durability, extending service life even under rigorous operating conditions and significantly reducing downtime and maintenance costs.

The barrel is treated with a nitriding coating — a surface hardening process that greatly enhances hardness and corrosion resistance. The nitriding treatment achieves a surface hardness ranging from HV950 to HV1100, improving wear resistance against abrasive materials and prolonging operational lifespan. The coating also imparts excellent corrosion resistance, ensuring the barrel maintains its integrity and performance even in harsh chemical environments.

Precision and alignment are central to the design. Strict tolerances and high-quality manufacturing standards ensure consistent performance and reduced mechanical stress, contributing to smoother material flow, better mixing, and uniform temperature distribution throughout the extrusion process. The product is versatile and adaptable, compatible with a wide range of polymers and materials — from plastic films and pellets to composite materials — providing the mechanical and thermal properties needed to optimize extrusion.
