Introduction
Changzhou Tili Precise Gearbox Co., Ltd. (常州泰利减速机有限公司), also referenced in company listings as Changzhou Tili Reducer Co., Ltd., is a Chinese manufacturer of industrial gearboxes and transmission products based in Changzhou, Jiangsu Province. The company’s core business centers on extruder gearboxes, helical gear reducers, cycloidal pinwheel reducers, and precision planetary gearboxes, with application areas that include plastics, rubber, petrochemicals, metallurgy, mining, lifting, and light industry.
Within the plastics sector, Tili is primarily associated with gearbox systems used in single-screw extruders and conical twin-screw extruders, where torque transmission, speed reduction, and gear durability are critical to stable processing. Its official and exhibitor-facing profiles indicate that the company exports to markets including Europe, the United States, Japan, India, Brazil, and Southeast Asia, and it positions itself as a supplier of transmission equipment for both domestic and international industrial customers.
History and Development
Changzhou Tili was established in 2003, according to third-party company profiles and product listings. Since then, it has developed from a reducer manufacturer into a broader transmission supplier with a product mix spanning gearbox types used in plastics processing and general industrial machinery.
Several milestones are repeatedly highlighted across company and marketplace descriptions:
- In 2003, the company was founded and began focusing on hardened-surface transmission products, especially extruder gearboxes.
- By 2020, a third-party profile reported that the company had obtained a national high-tech enterprise certificate, reflecting recognition of its technology and development capability.
- Current product and exhibitor pages show a broadened portfolio that includes planetary reducers, R/K/F/S helical gear reducers, ZLYJ single-screw extruder gearboxes, DJYG high-torque extruder gearboxes, and cycloidal reducers.
Business Operations and Positioning
Tili’s business is organized around the manufacture of power transmission equipment for industrial applications, with a particular emphasis on gearboxes designed for demanding torque and duty-cycle requirements. Its company materials describe the business as serving OEM and ODM-oriented demand, and marketplace listings describe it as a manufacturer/factory and trading company.
The company’s industrial positioning is shaped by three features:
- Specialization in extrusion drive systems, especially for plastics and rubber machinery.
- Breadth of reducer formats, allowing it to serve adjacent industrial sectors beyond plastics.
- Export orientation, with sales reported across multiple foreign markets.
Products and Technologies
Tili’s product line is built around gear-driven transmission systems that convert motor input into usable torque and controlled rotational speed. The company’s publicly described product families include:
- DJYG high-torque extruder gearboxes
- ZLYJ single-screw extruder gearboxes
- SZ and SZL conical twin-screw extruder gearboxes
- R, K, F, S helical gear reducers / gear motors
- B/X cycloidal pinwheel reducers
- Precision planetary gearboxes
Technical descriptions in marketplace listings indicate that some products use hardened tooth surfaces, helical gears, and coaxial layouts, with ratios reported across wide ranges depending on the model. One listing describes a ZLYJ series gearbox with multiple installation types, CE and ISO certification, and a typical power range of 0.12 kW to 160 kW for related gearbox offerings.
The company also states that it has invested in equipment for hard-gear machining and inspection, including gear grinding machines from Germany and Switzerland, gear testing instruments, gear hobbing machines, large boring and milling machines, and Japanese machining centers. These capabilities are relevant in gearbox manufacturing because tooth-surface finishing, dimensional accuracy, and inspection quality directly affect noise, heat generation, service life, and load performance.
Applications and End Markets
Tili’s products are used in a range of industrial sectors, but its strongest association is with plastic and rubber processing machinery. In plastics applications, extruder gearboxes are central to conveying and plasticizing polymer feedstock, making torque stability and thermal robustness especially important.
The company’s stated end markets include:
- Plastics and rubber processing
- Metallurgy and mining
- Petrochemical equipment
- Lifting and transport systems
- Light industry and food-related machinery
- Industrial automation and general machinery
Some marketplace listings also associate its gearboxes with agricultural machinery and marine applications, reflecting the broader applicability of gear reduction technology across industrial drive systems.
Global Presence and Market Reach
Company profiles state that Tili’s products are exported to dozens of countries and regions, including Europe, the United States, Japan, India, and Brazil. This export orientation suggests that the company competes not only in China’s domestic machinery supply chain but also in price- and specification-sensitive overseas industrial markets.
Its online exhibitor presence at CHINAPLAS identifies the company as a plastics-related supplier, reinforcing its visibility within one of the plastics industry’s major trade exhibition ecosystems. The CHINAPLAS marketplace listing currently shows limited public information, but it confirms the company’s participation in a plastics-industry supplier directory.
Manufacturing Capability and Quality Control
Tili’s published materials emphasize hardened gear processing and a manufacturing setup that includes CNC machines and specialized gearbox production lines. One marketplace profile reports two production lines, CNC production machines, one QA/QC inspector, and ISO9001:2015 management system certification.
These production details are consistent with the requirements of gearbox manufacturing, where repeatability, gear accuracy, and surface hardness are major quality factors. For extruder gearboxes in particular, the combination of load, temperature, and continuous operation places above-average demands on heat treatment, machining precision, and final inspection.
Sustainability and Environmental Considerations
Publicly available company information does not provide a detailed sustainability report or quantified environmental targets. As a gearbox manufacturer, however, Tili’s products contribute indirectly to industrial energy use through transmission efficiency, mechanical reliability, and reduced downtime, all of which can affect process efficiency in plastics and other manufacturing lines.
At the same time, gearbox manufacturing and plastics-processing equipment are both subject to broader industry pressures related to energy efficiency, material durability, and equipment life-cycle management. In the absence of detailed disclosures, the company’s environmental performance cannot be assessed beyond its published product and certification information.
Financial Scale and Economic Profile
No audited financial statements or revenue figures were found in the provided search results. Available marketplace data instead indicate a small-to-mid-sized manufacturing profile, including a reported registered capital of RMB 500,000, a plant area of 4,555.5 square meters, and 29 employees in one supplier listing.
These figures should be treated as marketplace-reported company data rather than independently audited financial disclosure. They nevertheless suggest a specialized manufacturer operating at a modest scale relative to large multinational drive-system groups.
Leadership and Corporate Information
Third-party company data identify He Xiujuan as the legal representative of the company and give the establishment date as 12 March 2003. Public sources in the search results do not provide a full board structure or detailed governance disclosures.
The company’s publicly presented corporate identity emphasizes technology-oriented manufacturing, customer service, and a philosophy of long-term operation and product quality. Those statements are consistent with its focus on industrial transmission products, where customer retention often depends on product reliability and application support.
Innovations and Future Outlook
The company’s strongest innovation signals are tied to its gearbox specialization, machining capability, and patent claims. One source states that Tili has obtained more than twenty patent certificates for projects including high-torque reducers. If accurate, this would indicate an internal emphasis on mechanical design refinement rather than broad product diversification.
Looking ahead, Tili’s prospects are likely to be shaped by several industry factors:
- Continued demand for extrusion equipment in plastics and rubber processing.
- Ongoing customer preference for hardened, low-noise, high-efficiency gear systems in industrial drives.
- Competitive pressure from domestic and international gearbox suppliers serving similar end markets.
- Greater emphasis on efficiency, service life, and maintenance reduction in industrial power transmission.
