We not only manufacture custom gearboxes for twin-screw extruders but also provide comprehensive repair, maintenance and replacement services for transmission gearboxes of equivalent specifications. We have successfully repaired and replaced numerous gearboxes manufactured by leading German and Japanese twin-screw extruder manufacturers, including W and P, Coperion, Toshiba, JSW, Kobe, Leistritz, Maris, PIV and Eisenbeiss, among others.

• Performance equivalent to international leading brands including German Flender, Austrian Eisenbeiss, W and P, Berstorff, Leistritz, JSW and Toshiba
• Maximum specific torque up to 15 Nm/cm³
• Radial bearings on dual output shafts are theoretically free of radial load, ensuring consistent precision throughout the entire service life
• Designed nominal service life up to 72000 hours, approximately 10 years under normal operating conditions
• Maximum input speed up to 1750 rpm
• Tight screw clearance reduces material backflow, shortens material residence time in barrels and minimizes excessive shear
• Extruders equipped with our gearboxes achieve 1 to 2 times higher output compared with low-torque extruders of the same screw diameter
• Premium component configuration with bearings from Sweden SKF and Germany INA, and oil seals imported from Germany

We are dedicated to the development, design and manufacturing of co-rotating and counter-rotating parallel twin-screw extruder production lines. Our extruders feature high torque, high efficiency, low energy consumption, excellent price to performance ratio and long service life, with a designed gearbox service life of up to 72000 hours. We keep pace with the most advanced extruder manufacturers worldwide.

Our comprehensive product and service portfolio includes:

• Complete twin-screw extruder production lines
• High-torque reduction gearboxes
• Automatic long fiber reinforced thermoplastic composites (LFT-D) production lines
• Counter-rotating parallel twin-screw extruders
• Differential concentration mixers
• Large component repair and precision machining
• Custom design and manufacturing of screw elements for all Japanese and German extruder models
