30 to 51mm Twin Screw Extruder Gearbox Replace and Overhaul Service for Speed Upgrade

We provide professional gearbox replacement, overhaul and speed upgrade services for all mainstream imported twin-screw extruder brands, including Coperion, Toshiba, Maris, Leistritz and JSW. Adopting our proprietary bilateral symmetrical gear drive system, our upgraded gearboxes feature a designed service life of over 72000 working hours and an average torque coefficient of 10.4. All core bearings are sourced from Sweden SKF and Germany INA, ensuring stable high-torque output. Our service helps customers achieve significant speed increase, production capacity improvement and equipment service life extension at a fraction of the cost of original replacement.

• World-class Bilateral Symmetrical Transmission Technology: Our core transmission technology is on par with international top-tier brands. The unique symmetrical design eliminates unilateral shaft load, significantly improving gearbox load capacity and operational stability.
• Ultra-long Service Life: Optimized structural design and premium materials ensure a standard designed service life of over 72000 working hours, supporting continuous stable operation for up to 10 years.
• High-performance Core Components: All gearboxes are equipped with internationally renowned Sweden SKF and Germany INA bearings, as well as imported German oil seals, guaranteeing ultra-high reliability of the transmission system.
• Comprehensive Performance Upgrade: Compared with original old gearboxes, our upgraded products can achieve 20%-50% speed increase, 30%-60% production capacity improvement and 15%-20% energy consumption reduction.
• Perfect Compatibility: All gearboxes are manufactured according to original equipment dimensions, achieving 100% direct replacement without modifying the extruder body.

• Reinforcement Modification: PP, PA, PBT, ABS, PC, POM, PPS, PET reinforced with carbon fiber and glass fiber
• Filler Modification: PE, PP, EVA filled with calcium carbonate, talcum powder, titanium dioxide, carbon black and other inorganic fillers
• Masterbatch Production: Color masterbatch, flame retardant masterbatch, carbon black masterbatch, degradable masterbatch and various functional masterbatches
• Plastic Alloy Compounding: PC+ABS, PA+ABS, PA+PE, PBT+PET and other high-performance polymer alloys
• Special Engineering Plastics Processing: PEEK, PEI, PPS, PPSU, PA6T, PA9T, LCP and other high-temperature resistant materials
• High-dispersion Compounding: Nano material dispersion, powder coating processing and high-grade fiber grade masterbatch production
• Reaction Extrusion: In-situ polymerization and polycondensation reaction extrusion processes
