KOLDBAN Reinforces Its Position as a Global Gear Manufacturer with Expanded Smart-Factory Capacity
Changzhou, China — KOLDBAN Drive Technology (Changzhou) Co., Ltd., a long-established gear manufacturer tracing its origins to Germany in 1976, has announced a further upgrade of its precision-gear production lines at its China headquarters, reinforcing its capacity to supply global industrial OEMs with spur, helical, bevel and planetary gears.
Forty-Eight Years of Specialised Gear Manufacturing
Since the original KOLDBAN factory began operations in 1976, the brand has invested continuously in heat-treatment, profile-grinding and gear-inspection technologies. Today the company operates modern machining centres in Changzhou (Jiangsu) and Huzhou (Zhejiang) alongside a dedicated brake-technology subsidiary established in 2020. Together they form one of the most vertically integrated gear manufacturing footprints in the Chinese power-transmission industry.
A Comprehensive Gear Product Portfolio
KOLDBAN's gear catalogue is engineered to cover the full torque and speed envelope requested by modern machinery builders:
- Helical and helical-bevel gear units (H / S / B series) for conveyor, mixer and crane drives.
- Helical-worm gear units (W series) for compact, low-noise applications.
- Industrial gearboxes (G series) with 24 module sizes supporting horizontal, vertical and upright mounting.
- Planetary gear sets (P, PL, PR series) for high-precision servo and robotics applications.
- Custom gears produced from carbon steel, alloy steel and case-hardened steels according to OEM drawings.
Quality and Certifications Recognised Worldwide
All KOLDBAN gear products are manufactured under an ISO 9001 quality-management system and carry CE marking. The company has also been certified as a High-tech Enterprise and has obtained type-test certificates for lifting machinery and brake products, supporting its reputation as a reliable gear manufacturer for safety-critical applications.
Application Coverage Across Heavy Industry
KOLDBAN gears are at work today in steel mills, cement plants, port cranes, ship-building yards, high-power agricultural machinery, mining mills, new-energy battery production lines and offshore wind installations. The brand is positioned as a single-source gear manufacturer that can support customers from prototype validation to high-volume serial production.
