Introduction
YILI MACHINERY (张家港市亿利机械有限公司) is a Chinese manufacturer of plastic processing equipment founded in 1994 and based in Zhangjiagang, Jiangsu Province. The company focuses on three main product areas: plastic extrusion machinery, plastic mixing machinery, and plastic recycling machinery, serving customers that need equipment for pipe, profile, compounding, washing, shredding, and pelletizing applications.
In the plastics industry, YILI MACHINERY is positioned as an equipment supplier rather than a polymer producer or plastics processor. Its product portfolio reflects two of the sector’s most important industrial themes: the expansion of pipe and profile extrusion capacity and the growth of mechanical recycling infrastructure for post-consumer and post-industrial plastics. Company materials also state that it has been recognized as a national high-tech enterprise, a national-level torch-plan enterprise, and a provincial contract-honoring enterprise, indicating a degree of official recognition within China’s manufacturing ecosystem.
History and Development
YILI MACHINERY states that it was established in 1994 and has developed over more than two decades into a specialized plastics machinery manufacturer. Some third-party listings give 1991 as the founding year, but the company’s own current materials consistently cite 1994.
Several milestones are visible in publicly available records:
- The company expanded from general plastics machinery into a structured three-division model covering extrusion, mixing, and recycling equipment.
- It reports more than 70 national patents, reflecting sustained in-house development in machinery design and related process technologies.
- It has been included in official Chinese innovation and quality-related lists, including high-tech enterprise and science-and-technology SME recognition materials published by government or government-linked sources.
The company is also listed on industry platforms and exhibition marketplaces, including the Chinaplas exhibitor directory, which situates it within the wider international plastics machinery supply chain.
Business Operations and Structure
YILI MACHINERY operates as a manufacturer with a core base in Jinfeng Town, Zhangjiagang City, an area known for plastics machinery production and export-oriented industrial activity. Company materials indicate that it also operates through an affiliated import and export business, supporting overseas sales and trade activity.
Its business model combines:
- Equipment design and manufacturing
- Process-line integration
- After-sales service and technical support
- Domestic and export sales
The company’s public descriptions emphasize a team structure spanning R&D design, manufacturing, and sales/service, suggesting that it is organized around project-based machinery delivery rather than standardized consumer-style production.
Products and Technologies
YILI MACHINERY’s equipment range centers on industrial plastic processing systems, particularly for pipes, profiles, recycling, and compounding.
Main product categories
- Plastic extrusion machinery
- Plastic mixing machinery
- Plastic recycling machinery
Representative equipment and process capabilities
| Category | Examples |
|---|---|
| Extrusion lines | PE/PP/PPR/PVC pipe extrusion lines, large-diameter PE/PP double-wall corrugated pipe lines, plastic profile extrusion lines |
| Mixing systems | High-speed mixers, heating/cooling mixer units, automatic weighing and conveying systems |
| Recycling systems | PE/PP washing lines, PE/PP recycling and granulation lines, PET bottle washing lines, high-efficiency shredders |
The company’s PET bottle washing line is described as a system for converting baled, contaminated PET bottles into clean PET flakes suitable for polyester staple fiber production or further pelletizing, with reported capacities from 500 kg/h to 3,000 kg/h.
Technically, this product mix places YILI MACHINERY in several important segments of plastics processing equipment:
- Pipe extrusion, where line stability, melt homogeneity, screw design, and output consistency are critical
- Industrial mixing, where dispersion and controlled dosing matter for PVC and other compounded formulations
- Mechanical recycling, where washing, sorting, shredding, drying, and granulation performance determine downstream recyclate quality
Applications and End Markets
YILI MACHINERY’s systems appear to serve a broad set of plastics applications, especially where continuous production lines are required.
Primary end-use sectors
- Water supply and drainage pipe production
- Gas and utility pipe production
- Irrigation and agricultural piping
- Building materials and construction profiles
- Plastic recycling and waste recovery operations
- Compounding and material preparation plants
The company’s product descriptions and third-party profiles also indicate sales into overseas markets, including Asia, the Middle East, Africa, Eastern Europe, and parts of the Americas.
Global Presence and Market Position
YILI MACHINERY is headquartered in Zhangjiagang, a city widely associated with China’s plastics machinery cluster and export manufacturing base. That location supports access to industrial suppliers, logistics networks, and export channels.
The company’s market positioning appears to be that of a mid-sized specialized machinery manufacturer with export orientation, rather than a diversified multinational equipment group. Public-facing listings describe sales in more than 70 countries and broad domestic market coverage, though these claims are company-reported and not independently quantified in the available sources.
Its presence on Chinaplas’s exhibitor platform and other industrial directories indicates active participation in the plastics machinery trade ecosystem, where visibility at exhibitions and online marketplaces is important for lead generation and international distribution.
Sustainability and Environmental Initiatives
YILI MACHINERY’s most direct sustainability relevance lies in its recycling machinery business. By supplying washing, shredding, and granulation lines for PE/PP and PET waste streams, the company contributes to material recovery infrastructure that supports plastic circularity.
The company’s public materials also mention recognition as a provincial-level contract-honoring enterprise and a high-tech enterprise, while government listings identify it among innovation-oriented and green-manufacturing-related enterprise programs. These designations do not by themselves prove specific environmental performance, but they do suggest alignment with China’s broader policy emphasis on cleaner, more efficient industrial upgrading.
At the same time, as with most plastics machinery manufacturers, the company’s environmental role is dual-sided: it enables both the production of plastics components and the recovery of discarded plastics. The net sustainability impact therefore depends on how its equipment is deployed by downstream users and how effectively recyclate can re-enter manufacturing loops.
Financial Performance and Economic Impact
No audited public financial statements were found in the provided sources, so detailed revenue, profitability, or asset figures cannot be stated reliably. The company’s economic footprint is better observed through its manufacturing role, patent portfolio, export activity, and recognition in technology-oriented enterprise lists.
Its broader economic contribution is associated with:
- supplying capital equipment to plastics processors,
- supporting industrial automation and process efficiency,
- enabling recycling capacity in domestic and export markets,
- and contributing to the machinery cluster economy of Zhangjiagang.
Leadership and Corporate Governance
Public sources identify the company with its Chinese legal entity name, 张家港市亿利机械有限公司, and note an affiliated export-trading company in some company descriptions. Available materials do not provide a full governance profile, board structure, or executive roster.
Third-party directories and trade platforms associate the company with Chen Hezhong as a legal representative in some records, but the company’s own materials emphasize engineering and manufacturing capability rather than leadership disclosure.
Innovations and Future Outlook
YILI MACHINERY’s future prospects are tied to several industry trends:
- Demand for energy-efficient extrusion lines
- Growth in plastic recycling and secondary raw materials
- Automation in mixing, feeding, and conveying systems
- Rising quality requirements for pipe, profile, and recyclate applications
The company’s patent base and high-tech recognition suggest continued emphasis on in-house engineering improvement. In practical terms, future competitiveness in this segment will likely depend on line stability, energy consumption, automation, service support, and the ability to meet different national standards for pipe, recycling, and compounding equipment.
Summary
YILI MACHINERY is a Zhangjiagang-based plastics machinery manufacturer best known for extrusion, mixing, and recycling equipment. Its portfolio reflects major industrial priorities in the plastics sector: efficient production of pipe and profile products, and the expanding need for plastics recovery and reprocessing systems.
