Changzhou, China – Established in 2011 and situated in Wujin Economic Development Zone of Changzhou, a city known as an international garden city, Changzhou Kaiyuan Defu Reducer Co., Ltd. is a professional reducer manufacturer integrating independent research and development, mass production and global sales. Rooted in the industrial transmission sector, the enterprise has grown into a trusted supplier of matched drive parts for plastic and rubber processing Industrial Equipment, and it has recently launched its upgraded High Load-Bearing Hard Tooth Surface Gear Reducer to enrich its full-range product portfolio.
This newly launched hard tooth surface gear reducer covers K, R, F and S series with superior load resistance, quiet running and leak-proof performance built for heavy-duty production scenarios. It achieves a maximum output torque of 200Nm, a broad speed ratio range from 5.36 to 106.38, and matches motor power between 0.29 kilowatts and 4.07 kilowatts. Multiple output shaft directions, installation angles, motor terminal box layouts and eight distinct assembly structures allow seamless matching with different mechanical layouts. Benefiting from the company’s mature precision processing technology and premium component configuration, the gearbox delivers outstanding High Efficiency, cutting energy loss during long continuous production cycles.
All products adopt top-tier manufacturing materials: integrally cast high-rigidity cast iron housings, alloy steel gears processed through carburizing, quenching and precision grinding, well-known brand bearings and imported oil seals from NAK, SOG and SIMIRIT. These premium parts bring stable operation, low vibration and extended service life. The reducer serves as a core drive component for mainstream plastic processing workflows. It supplies steady torque control for Plastic Extrusion lines producing plastic sheets, profiles and pipes, delivers smooth low-noise operation for Film Blowing units to guarantee uniform film thickness throughout full Quality Film Production workflows, and provides consistent power output for Plastic Pelletizing equipment handling both new and recycled plastic raw materials. Besides plastic processing, the reducer also fits wire drawing and wire cable manufacturing lines with precise speed regulation.
Sticking to the operation tenet of exquisite manufacturing and customer priority, the firm implements full-process quality testing from raw material admission to finished product delivery. A professional technical and after-sales team stands ready to fulfil customised development requests for clients worldwide. With complete product specifications, sufficient stock, customisation support and one-stop purchasing services, Changzhou Kaiyuan Defu Reducer Co., Ltd. will keep advancing transmission technology and product optimisation, welcoming buyers from all regions to visit the factory and negotiate win-win cooperation.
