Twin Screw Gearbox Manufacturer
Zhitian delivers high-torque twin screw gearboxes engineered for extreme reliability and energy efficiency. Our gearboxes are custom-built to synchronize seamlessly with extruder barrels, ensuring optimal power transmission for polymers, bio-materials, and industrial compounds.
Industrial Twin Screw Gearbox Custom Solutions
Zhitian’s twin screw gearboxes unify CNC-machined ductile iron housings with deep-nitrided alloy steel gears (ISO 1328 6+) for precision and strength. Engineered to handle ultra-high torque loads (≤18 Nm/cm³), our gearboxes are trusted in plastics, rubber, food, feed, and new energy industries. Proven grinding-polishing processes ensure smooth power transmission and extended service life under 24/7 operations. Custom torque configurations (<8 to 18 Nm/cm³) adapt seamlessly to diverse industrial demands, backed by rigorous quality control and material durability.
Custom Twin Screw Gearbox Solutions
Zhitian specializes in high-torque twin screw gearboxes (up to 18 Nm/cm³) for demanding industries like rubber, plastics, and new energy. Leveraging 20+ years of design expertise, our gearboxes are optimized for extreme shear forces and abrasive materials (e.g., carbon-reinforced polymers, battery slurries).
Precision assembly techniques ensure near-zero backlash and 99%+ power transmission efficiency even under 24/7 heavy loads.Zhitian’s gearboxes ensure ultra-stable, low-noise operation through precision-balanced gears and vibration-dampened housings. Proven field-tested designs reduce energy waste and maintenance needs.
