Introduction
JIANGSU SHUANGJUN MACHINERY MANUFACTURE CO., LTD. (江苏双俊机械制造有限公司) is a Chinese manufacturer of plastic extrusion equipment based in Zhangjiagang, Jiangsu Province, with a product portfolio centered on complete production lines for flooring, boards, sheets, profiles, and pipes. The company is particularly associated with machinery for SPC, WPC, and LVT flooring, PVC foaming board and wall panel lines, and extrusion systems for PET, PLA, TPU, PP, PS/ABS, and pipe/profile applications.
In the plastics machinery sector, Shuangjun positions itself as a provider of turnkey extrusion line solutions, integrating process design, machine supply, and after-sales service for customer-specific production requirements. Its technical emphasis includes automated line control, multi-stage processing for rigid-core flooring, and extrusion configurations adapted to different output and thickness specifications.
The company’s public materials and exhibitor listings indicate participation in international plastics industry events, including CHINAPLAS-related exhibitor directories and DOMOTEX asia/CHINAFLOOR 2026, reflecting its focus on export-oriented and flooring-related machinery markets.
History and Development
Shuangjun’s online company materials describe it as a specialized plastics extrusion machinery manufacturer operating from Zhangjiagang’s industrial base, a region widely associated with machinery and plastics processing in Jiangsu. One company profile states that the firm has about 12 years of customized production experience, indicating development from a machinery producer into a line-solution supplier.
A 2022 local standards record lists Q/320582SJJ1-2022 “Plastic Sheet/Board Production Line” under the company’s unified social credit code, showing that Shuangjun has formalized product specifications for at least part of its extrusion-line business.
Public product pages and exhibition materials also show an ongoing expansion of its product scope, from flooring equipment into board, sheet, pipe, and profile production lines, suggesting a progression toward broader plastic extrusion systems rather than a single-machine focus.
Business Operations and Segments
Shuangjun’s business is organized around complete extrusion production lines rather than standalone downstream plastics products. Its main operational areas include:
- Flooring production lines for SPC, WPC, and LVT products.
- Board and sheet lines for PVC foaming board, wall panels, PP board, PET sheet, PLA sheet, TPU sheet, and PS/ABS sheet.
- Pipe and profile lines for PP/PPR/PE pipe and related profile applications.
- Wood-plastic and decorative interior lines, including wall cladding and related building-material applications.
Company materials state that it provides whole-line turnkey projects and customer-tailored solutions based on product specifications, output requirements, and material formulations.
Products and Technologies
Shuangjun’s most technically detailed offering is its SPC floor production line, which it describes as a fully automated system using conical twin-screw extrusion technology to process PVC and calcium carbonate into rigid-core flooring. The production sequence includes material mixing, extrusion lamination, cooling and shaping, surface treatment, cutting, and packaging.
The company publishes example configuration data for its SPC lines, including the following extruder models and capacities:
| Extruder model | Motor power | Material | Thickness | Width | Output |
|---|---|---|---|---|---|
| SJ-Z110 | 200 kW | PVC + CaCO₃ | 2–8 mm | 970–1220 mm | 1.2–1.5 t/h |
| SJ-Z115 | 200 kW | PVC + CaCO₃ | 2–8 mm | 970–1220 mm | 1.8–2.0 t/h |
| SJ-Z160 | 315 kW | PVC + CaCO₃ | 2–8 mm | 970–1220 mm | 2.8–3.0 t/h |
For larger flooring applications, company materials also describe a five-roll calendering system and list multiple screw and extruder configurations, including 92/188, 110/220, 115, 136, and 160 models, indicating line customization by output class and product format.
Across its broader product range, Shuangjun promotes machinery for:
- SPC/LVT/WPC flooring lines.
- PVC foaming board and wall panel lines.
- PET/PLA/TPU sheet lines.
- PP/PPR/PE pipe lines.
- PS/ABS sheet and profile lines.
Its public descriptions emphasize automation, stable output, precise control, and the integration of equipment into continuous processing systems suitable for industrial-scale production.
Applications and End Markets
Shuangjun’s equipment serves several plastics-processing end markets:
- Residential flooring, particularly rigid-core and decorative flooring formats.
- Commercial flooring and waterproof floor panels.
- Interior decoration materials, including wall panels and cladding.
- Construction and building products, especially board, profile, and pipe applications.
- Environmental and material-substitution applications, where company materials explicitly frame plastics processing as a replacement for wood in certain uses.
These end markets align Shuangjun with two broader industry trends: demand for automated extrusion lines and the expansion of wood-plastic, waterproof, and low-maintenance building materials.
Global Presence and Market Position
Shuangjun presents itself as an exporter and reports that its SPC flooring production equipment is shipped to markets worldwide, including the United States and Southeast Asia. Its company website also indicates overseas-oriented service positioning through English-language product pages and international exhibition announcements.
The firm appears in the CHINAPLAS eMarketplace exhibitor information database and in broader exhibitor directories for CHINAPLAS 2026, supporting its visibility within the plastics machinery trade-show ecosystem. Its participation in DOMOTEX asia/CHINAFLOOR 2026 also underscores its focus on flooring production technology as a commercial niche.
Research and Development
Company materials describe Shuangjun as supported by an independent R&D team and a technical service structure focused on customer-specific extrusion solutions. The firm’s published product pages and model tables suggest in-house process engineering for line configuration, automation, and extrusion matching across product categories.
A LinkedIn company profile also attributes to Shuangjun several technical claims, including a counter-rotating parallel twin-screw extruder for SPC flooring, a four-speed gearbox patent, and extended screw life and energy-saving performance claims. These statements are company-associated claims rather than independently verified performance measurements.
Sustainability and Environmental Initiatives
Shuangjun’s public materials emphasize machinery for SPC, WPC, and other plastic-wood substitution applications, which the company presents as part of the industrial shift from wood-based to plastic-based materials in some building-product uses. Its SPC flooring descriptions also highlight formaldehyde-free and 100% waterproof product characteristics of the flooring output produced by the line, reflecting the materials logic of rigid-core PVC-composite flooring systems.
The company’s broader portfolio in PET and PLA sheet lines suggests participation in the machinery segment used for materials that can support lightweight packaging and thermoformed products, although the environmental performance of such materials depends on end-use design, recycling access, and local waste systems.
Quality Management and Certifications
Shuangjun’s Chinese-language company profile states that it adheres to export standards and holds EU-related certification qualifications. The same material also highlights 24-hour after-sales service and a service model centered on installation support and long-term machine operation.
Its presence in a local standard supervision record for a formal product standard further indicates some degree of documented product specification and regulatory alignment in its machinery lineup.
Innovations and Future Outlook
Shuangjun’s product messaging points toward continued emphasis on automation, throughput, and process integration in extrusion lines, especially for SPC flooring and board-sheet systems. The company’s exhibition activity and product breadth suggest a strategy of extending from core flooring machinery into adjacent sheet, profile, and pipe markets where similar extrusion competencies can be applied.
In industry terms, the company is positioned within a segment shaped by demand for high-output, energy-conscious extrusion lines, tighter dimensional control, and turnkey delivery for manufacturers serving construction and interior-material markets.
