Bimetallic screw barrels face wear, corrosion, and thermal stress in processing. This article explains durability mechanisms, materials, manufacturing, and lifespan factors.

Explains how screw and barrel design affects processing efficiency, melt stability, energy use, and long-term performance in extrusion and injection molding.

Explores advanced twin screw and barrel material innovations for 2026, helping manufacturers improve wear resistance, uptime, and extrusion reliability.

High-wear extrusion and injection cause rapid barrel degradation; bimetallic screw barrel materials improve abrasion resistance, corrosion control, and long-term process stability.

Abrasive fillers and corrosion shorten barrel life; comparing nitrided and bimetallic barrels helps engineers balance wear resistance, cost, and long-term extrusion stability.

Injection molding often suffers from melt inconsistency and wear—optimized screws and barrels improve plasticizing stability, melt quality, and long-term production efficiency.
