Introduction
Zhangjiagang City Xinlai Machinery Co., Ltd. (Chinese: 张家港市鑫来机械有限公司) is a Chinese manufacturer and exporter of plastics-processing machinery based in Zhangjiagang, Jiangsu Province. The company integrates equipment design, development, manufacturing, and international sales, with a product portfolio centered on extrusion, plastic-pipe and profile production, recycling and pelletizing, and auxiliary machinery.
Established in 2007, Xinlai operates within Zhangjiagang’s specialized plastics-machinery cluster near Shanghai and the Yangtze River Delta manufacturing region. Its stated export markets include Europe, Asia, Australia, Central and South America, Eastern Europe, and the Middle East and Africa. The company’s position in the plastics industry is that of an equipment supplier serving processors that require complete or partially integrated production lines rather than a producer of polymer materials or finished plastic goods.
Its principal technology areas include plastic extruders, HDPE, PVC and PP pipe lines, PVC profile extrusion systems, and recycling and granulation lines for materials such as PVC, PE, PP and PET. The company also supplies supporting equipment including crushers, shredders, pulverizers, mixers, dryers, loaders, printers, grinders, winders, molds, and belling machines.
History and Development
Xinlai Machinery was established in 2007. Its development reflects the expansion of Zhangjiagang as a manufacturing base for plastics-processing equipment and the wider growth of Chinese machinery exports to processors in emerging and established plastics markets.
Key development milestones include:
- 2007: Establishment of Zhangjiagang City Xinlai Machinery Co., Ltd.
- Product portfolio expansion: Development from individual extrusion equipment toward complete pipe, profile, recycling, and auxiliary-machine systems.
- International market development: Expansion of export activity to customers across Europe, Asia, Australia, the Americas, and the Middle East and Africa.
- Industry-platform participation: Listing as an exhibitor on the CHINAPLAS eMarketplace, where the company is identified as a plastics-machinery supplier.
This trajectory corresponds with a broader shift in plastics machinery toward integrated production lines, localized technical support, and equipment capable of processing both virgin and post-consumer or post-industrial plastics.
Business Operations and Segments
Xinlai’s operations can be grouped into four principal business segments:
| Segment | Main activities |
|---|---|
| Extrusion machinery | Manufacture and supply of plastic extruders and associated line equipment |
| Pipe production | Production lines for HDPE, PVC and PP pipes |
| Profile production | PVC door, ceiling, and other profile extrusion systems |
| Recycling and auxiliary equipment | Recycling pelletizing lines and machines for size reduction, mixing, drying, conveying, and downstream handling |
The company describes itself as a manufacturer, exporter, and integrated plastics-machinery supplier. Its business model combines standardized equipment with project-specific configurations for material type, product geometry, throughput, automation level, and downstream finishing requirements.
For processors, this structure can reduce the need to source every machine from a separate vendor. At the same time, complete-line projects require coordination among extrusion, cooling, calibration, haul-off, cutting, winding, conveying, and control systems. The practical performance of such installations therefore depends not only on individual machines but also on line integration, commissioning, process control, and after-sales technical service.
Products and Technologies
Plastic extruders
Extruders form the core of Xinlai’s product range. In plastics manufacturing, an extruder melts and conveys polymer through a die to create continuous products such as pipes, profiles, sheets, films, or compounds. Equipment configuration varies according to polymer properties, product dimensions, required output, and the degree of material reprocessing.
Typical engineering considerations include:
- Screw diameter and effective screw length
- Screw design and compression ratio
- Heating and cooling-zone configuration
- Melt-temperature control
- Die and tooling compatibility
- Drive power and output stability
- Vacuum calibration and downstream haul-off
- Automatic cutting, winding, or stacking
The company’s extrusion systems are associated primarily with PVC, PE, PP, ABS, and related thermoplastics.
Pipe production lines
Xinlai supplies production lines for HDPE, PVC, and PP pipes. A typical pipe line may combine an extruder, pipe die, vacuum calibration tank, spray-cooling tank, haul-off unit, cutting machine, and stacker or winder.
Different materials require different processing approaches:
- HDPE and PP: Commonly processed through single-screw extrusion with controlled melt temperature and cooling to preserve dimensional stability.
- PVC: Requires careful thermal management because excessive residence time or temperature can cause degradation. Twin-screw extrusion is frequently used for rigid PVC formulations, although final equipment selection depends on the formulation and product specification.
- Large-diameter pipe: Requires stronger haul-off, more extensive cooling, and higher-capacity calibration and cutting equipment than small-diameter products.
Pipe-line performance is generally assessed through output consistency, wall-thickness uniformity, dimensional accuracy, surface quality, energy use, and changeover efficiency.
PVC profile extrusion
The company supplies extrusion systems for PVC doors, ceilings, and other profiles. Profile lines typically incorporate a conical or parallel twin-screw extruder, profile die, calibration table, cooling system, haul-off, and cutting or stacking equipment.
Profile production presents technical challenges that differ from pipe extrusion. Complex cross-sections require precise die balancing and calibration, while surface appearance, dimensional tolerances, corner definition, and resistance to warping are important product characteristics. Tooling and downstream calibration are therefore central to the performance of a profile line.
Recycling and pelletizing lines
Xinlai lists recycling and granulation lines for PVC, PE, PP, and PET. These systems can be configured for post-industrial scrap, production waste, or selected post-consumer streams, depending on contamination levels and material consistency.
A recycling line may include:
- Sorting and feed preparation
- Crushing or shredding
- Washing and separation, where required
- Drying or dewatering
- Size reduction or pulverization
- Extrusion and melt filtration
- Pelletizing
- Cooling, drying, and bagging
The suitability of a recycling line depends strongly on feedstock composition. Clean, homogeneous production scrap is generally easier to reprocess than mixed, contaminated, or heavily filled post-consumer material. PVC recycling also requires formulation-specific thermal control, while PET commonly demands effective drying before melt processing because moisture can reduce polymer molecular weight during extrusion.
Auxiliary machinery
Supporting equipment listed by Xinlai includes:
- Crushers
- Shredders
- Pulverizers
- Mixers
- Dryers
- Loaders and conveying equipment
- Printers
- Grinders
- Winders
- Belling machines
- Molds and other production-line components
Auxiliary equipment influences overall line productivity. For example, shredders and crushers determine feed size, mixers affect additive distribution, dryers influence moisture-sensitive processing, and haul-off or winding systems affect the handling of continuous products.
Applications and End Markets
Xinlai’s equipment serves several major plastics-processing applications:
- Construction: Water pipes, drainage pipes, electrical conduits, window and door profiles, ceiling profiles, and related building products
- Infrastructure: HDPE and PP piping systems for water, irrigation, gas distribution, and industrial services
- Consumer and industrial products: Extruded profiles, molded or formed plastic components, and recycled polymer feedstock
- Recycling: Conversion of plastic scrap into reusable pellets for subsequent extrusion or molding
- Packaging-related processing: Selected applications involving recycled PET, PE, PP, and auxiliary processing systems
Demand for these applications is influenced by construction activity, infrastructure investment, polymer prices, waste-management regulation, and the availability of recycled feedstock. Pipe and profile machinery is also affected by national standards, dimensional requirements, and local preferences for PVC, PE, or PP systems.
Global Presence and Market Position
Xinlai is located in Jinfeng Town, Zhangjiagang, approximately 100 kilometres from Shanghai according to company-related supplier information. The location provides access to the Yangtze River Delta industrial base, port infrastructure, machinery suppliers, and a dense network of plastics-processing companies.

Research and Development
The company describes its activities as integrating research and development with manufacturing and trade. In plastics machinery, research and development commonly focuses on improving melt stability, throughput, energy efficiency, automation, material flexibility, and the processing of recycled polymers.
Relevant development areas for Xinlai’s product categories include:
- Screw and barrel designs adapted to PVC, PE, PP, PET, and mixed recycling streams
- Improved temperature and pressure control
- More reliable melt filtration and pelletizing
- Higher-efficiency drives and heating systems
- Automated fault detection and process monitoring
- Modular line layouts for different product dimensions
- Reduced material loss during start-up and changeover
For recycling applications, engineering development must also address feedstock variability. Stable operation depends on controlling contamination, moisture, bulk density, particle size, and melt filtration requirements.
Sustainability and Environmental Initiatives
Xinlai’s recycling and pelletizing equipment is directly connected with the plastics industry’s movement toward greater material circularity. By converting selected plastic waste into reusable pellets, such systems can support the substitution of recycled resin for a portion of virgin polymer consumption.
The environmental value of recycling machinery depends on operating conditions and the quality of the input stream. Important factors include:
- Electricity consumption per kilogram of recycled material
- Water use in washing systems
- Management of wastewater and separated contaminants
- Polymer yield and pellet quality
- The proportion of material diverted from disposal
- Transport distances for waste and recycled resin
- The end-use performance of recycled material
Recycling does not eliminate the need for waste prevention, product redesign, collection systems, or effective sorting. Mechanical recycling is most effective when feedstocks are sufficiently clean and compatible with the intended application. In demanding applications, recycled pellets may require blending, filtration, odor treatment, or additional compounding.
The company’s manufacturing information also identifies CE and SGS-related certification claims. These references concern conformity, testing, or inspection contexts and should be interpreted according to the specific machine, market, and certificate scope rather than as a universal certification covering every product.
Quality Management and Certifications
Quality assurance in plastics machinery involves both manufacturing controls and final-line performance. Relevant areas include:
- Dimensional accuracy of fabricated machine components
- Electrical-panel and control-system testing
- Pressure and temperature safety
- Welding and structural integrity
- Calibration of sensors and measuring devices
- Trial operation before shipment
- Documentation, installation, and commissioning
