Introduction
Nanjing Juli Chemical Machinery Co., Ltd. (南京聚力化工机械有限公司) is a Chinese manufacturer of plastics extrusion and pelletizing equipment based in Nanjing, Jiangsu Province. The company is best known for its co-rotating twin-screw extruders, tri-screw extruders, sheet extrusion lines, under-water pelletizing systems, and related auxiliary equipment, with a business model centered on equipment design, manufacturing, technical development, and after-sales service.
In the plastics machinery sector, Nanjing Juli occupies the niche of a process-equipment supplier serving polymer compounding, modification, and granulation applications, rather than a raw-material producer or plastics processor. Its product scope indicates a focus on high-shear mixing, compounding, and pelletizing, which are core steps in producing engineering plastics, masterbatch, degradable materials, elastomers, and specialty compounds.
History and Development
The company was established in 2005 according to several supplier and company-profile listings, and it is registered as a manufacturer in Nanjing. Some third-party directories give earlier founding dates, but the most consistent and locally grounded corporate-profile sources identify 2005 as the establishment year.
Key development characteristics include:
- Expansion into a specialized portfolio centered on twin-screw extrusion, degradation-material granulation, and sheet extrusion lines.
- Investment in production capacity and machining capability, including modern workshops and a substantial machine tool base reported by the company website.
- Accumulation of intellectual property, with the company stating that it holds utility model and invention patents.
The company also appears in multiple plastics-equipment directories and exhibitor databases, indicating sustained participation in domestic and international industrial marketing channels.
Business Operations and Segments
Nanjing Juli’s operations are organized around the development and manufacture of polymer processing equipment and supporting systems. Its business activities include:
- Equipment design and fabrication
- Technical development for compounding and modification processes
- Auxiliary machinery and spare parts supply
- After-sales service and engineering support
The company’s reported workforce size varies by directory, but public listings place it in the category of a small-to-mid-sized industrial manufacturer rather than a large multinational enterprise. Its operations are concentrated in Nanjing’s Jiangning District, with multiple addresses referenced in public listings and company contact pages.
Products and Technologies
Nanjing Juli’s product line is centered on extrusion and granulation systems used in plastics compounding and processing. The main equipment categories include:
- Co-rotating twin-screw extruders
- Tri-screw extruders
- Single-screw extruders
- Two-stage extruders
- Plastic sheet extrusion production lines
- Under-water pelletizing systems
- Side-feeder systems for twin-screw extruders
The company’s technical profile suggests experience in mixing, dispersing, devolatilizing, and pelletizing operations, which are central to plastic modification and masterbatch production. Under-water pelletizing systems are typically used for continuous polymer strand cutting in a controlled water environment, while twin-screw extruders are widely used for compounding fillers, additives, pigments, and engineered resin blends; Nanjing Juli’s portfolio is aligned with these process requirements.
The company also reports manufacturing capabilities for:
- Degradable-material pelletizing lines
- Elastic material underwater pelletizing equipment
- Laboratory and pilot-scale extrusion systems
- Auxiliary feeders and spare parts
According to its website, the company operates machining and quality-control equipment including machining centers, CNC boring machines, lathes, thread grinders, hardness testers, coordinate measuring instruments, and flaw detection equipment. It also states monthly barrel-processing capacity and annual production volumes for complete units, indicating a vertically integrated manufacturing model.
Applications and End Markets
Nanjing Juli’s equipment is used in downstream sectors that depend on compounding and pelletizing, including:
- Engineering plastics
- Masterbatch and color concentrates
- Automotive materials
- Wire and cable compounds
- Large-diameter plastic pipes
- Sheets and film-related processing
- Petrochemical and fiber-related applications
- Medical, agricultural, and defense-related material processing
The breadth of these applications reflects the role of twin-screw and granulation equipment in converting base polymers into formulated materials with specific mechanical, thermal, and processing properties.
Global Presence and Market Position
Public supplier listings indicate that Nanjing Juli exports to markets in Southeast Asia, the Middle East, India, North America, Eastern Europe, and North Africa. This export profile suggests a business model that combines domestic sales with international equipment supply through distributor and trade-platform channels.
The company is also listed in plastics-equipment directories and exhibition-related databases, which indicates visibility in the broader extrusion-machinery marketplace. Its market position appears to be that of a specialized Chinese extruder manufacturer focused on compounding and pelletizing solutions, operating in a highly competitive segment that includes numerous domestic and international machinery suppliers.
Sustainability and Environmental Initiatives
Nanjing Juli’s published product portfolio includes degradable-material granulation lines and related extrusion systems, which connect the company to the plastics industry’s shift toward alternative and more environmentally oriented material streams. Such equipment is relevant to the production of compostable or otherwise degradable polymer compounds, although the environmental performance of the final materials depends on the resin system, processing conditions, and end-of-life infrastructure.
The company’s public materials do not provide a detailed sustainability report, emissions inventory, or formal climate target. Its environmental profile is therefore best understood through its product focus on processing technology for alternative materials rather than through disclosed corporate sustainability metrics.
Financial Performance and Economic Impact
No audited public financial statements were identified in the available sources. As a privately held manufacturer, Nanjing Juli does not appear to publish detailed revenue, profitability, or capital-expenditure data in the sources reviewed.
Its economic impact is more visible through industrial employment, equipment manufacturing, and export activity. The company reports manufacturing facilities, machining capacity, and a range of processed equipment outputs, which indicate participation in the regional industrial supply chain around Nanjing’s machinery sector.
Leadership and Corporate Governance
Public listings identify the company as operating from Nanjing, Jiangsu, with management contact information available through supplier platforms and company pages. However, detailed board composition, ownership structure, and governance policies are not disclosed in the available sources.
Some third-party listings refer to named managers or contacts, but they do not provide a full governance profile comparable to that of a listed corporation. As a result, the company’s governance is best characterized as that of a private industrial manufacturer with operational leadership centered on technical sales and production management.
Innovations and Future Outlook
Nanjing Juli’s technical direction is consistent with broader plastics-industry trends toward:
- Higher-output compounding systems
- Improved mixing efficiency in twin-screw extrusion
- Pelletizing solutions for specialty and degradable materials
- Integrated auxiliary systems for stable continuous processing
Its reported patent holdings and in-house machining capabilities suggest an emphasis on incremental engineering refinement rather than platform disruption. Future competitiveness in this segment is likely to depend on process reliability, energy efficiency, screw-configuration flexibility, service responsiveness, and the ability to adapt equipment to new resin systems and circular-economy materials.
Summary
Nanjing Juli Chemical Machinery Co., Ltd. is a specialized Chinese plastics machinery manufacturer focused on extrusion-based compounding and granulation equipment. Its core identity is shaped by twin-screw extrusion technology, pelletizing systems, and custom process equipment for plastics modification and specialty materials.
