In the realm of modern polymer processing, the screw barrel stands as the cornerstone of extrusion equipment, with its performance directly determining product quality and production efficiency. Particularly for processes requiring precise control of material plasticization and mixing, the material selection, precision, and design of screw barrels are of paramount importance.
This examination focuses on a critical extrusion equipment component—the 90mm diameter carbon steel screw barrel. Developed by AR Mechanical Works through extensive manufacturing experience and advanced technology, this product meets diverse, high-standard production requirements. Its core advantages lie in meticulous material selection and processing techniques, ensuring exceptional wear resistance, corrosion resistance, and dimensional stability.
The barrel utilizes premium carbon steel as its primary material, providing superior mechanical strength and excellent machinability. The material's high hardness and toughness enable it to withstand high-pressure, high-temperature processing environments while effectively resisting material abrasion.
The 90mm diameter configuration makes this component ideal for medium-to-large-scale extrusion production lines, capable of handling larger material volumes to enhance production throughput.
A distinctive feature is the 2-3mm bimetallic layer. By overlaying a high-hardness, wear-resistant alloy coating onto the carbon steel substrate, the barrel demonstrates significantly improved corrosion and abrasion resistance. This composite structure proves particularly effective when processing plastics containing fillers, flame retardants, or glass fiber additives, substantially extending service life while reducing maintenance costs.
The screw maintains a linearity tolerance of 0.015mm, representing exceptional machining accuracy. This precise geometric configuration ensures uniform plasticization, effective mixing, and stable extrusion. Minimal linear deviation guarantees consistent material stress distribution along the screw, preventing localized overheating or uneven plasticization for uniform product quality.
The 0.5-0.8mm nitriding depth treatment further enhances surface hardness and wear resistance. This thermochemical diffusion process creates a high-hardness compound layer through nitrogen atom penetration, improving resistance to wear, fatigue, and corrosion—particularly valuable in high-shear and high-friction operating conditions.
The 90mm carbon steel screw barrel is currently available from stock, enabling rapid procurement and reduced equipment deployment timelines.
