The Jwell conical twin-screw extruder is specifically engineered for plasticized PVC compound processing — a material that demands gentle, thorough plasticization within a narrow thermal window to prevent dehydrochlorination and thermal degradation. The counter-rotating conical screw geometry delivers superior mixing efficiency with dwell times under 3 minutes, ensuring complete fusion of PVC resin, plasticizers, stabilizers, UV absorbers, and biocides without exceeding the compound’s thermal stability limit.
The cone-shaped screw profile creates a progressively decreasing channel depth from feed zone to metering zone, which naturally compresses the PVC melt while minimizing shear heating — a critical advantage over parallel twin-screw designs for heat-sensitive PVC formulations. This geometry achieves up to 20% higher output per unit of installed power compared to equivalent parallel twin-screw alternatives in PVC applications.
Key extruder specifications (JW-120/150 conical twin-screw):
– Screw diameter: 120/150 mm (cone tip/base)
– L/D ratio: 25:1
– Barrel zones: 5 independent PID heating/cooling zones

For mechanically attached single-ply roofing applications, reinforced PVC membranes are the industry standard. The optional precision reinforcement insertion station on the Jwell line places polyester scrim or glass fiber mesh accurately between the upper and lower PVC layers during the extrusion/calendering process.
The automatic edge-trimming photoelectric sensor maintains ±2 mm reinforcement placement accuracy across the full sheet width, preventing edge exposure that compromises weld integrity during roof installation. This system handles scrim weights from 80 to 250 g/m², producing reinforced PVC membranes that meet EN 13707 tear strength requirements exceeding 400 N for Type L roofing membrane classification.
The reinforcement unwind station includes:
– Pneumatic tension control with dancer roller feedback
– Photoelectric edge guide sensor (±1 mm)
– Quick-change scrim roll mandrel (< 5 minutes changeover)
– Anti-static bar for dust-free scrim feeding into the laminating nip
– Automatic splice detection and alarm

Consistent membrane thickness is the single most impactful quality parameter in PVC waterproofing — it directly controls membrane weight per square meter, the primary cost driver for roofing contractors who purchase by area. The Jwell line integrates an online beta-ray or laser thickness scanner that traverses the sheet width continuously, providing real-time measurement data to the Siemens S7-1200 PLC.
The closed-loop feedback system automatically adjusts both haul-off speed and die lip restrictor bar position to maintain target thickness within ±0.03 mm. Thickness data is logged at configurable intervals for full production traceability — a requirement increasingly specified by European roofing membrane procurement departments under ISO 9001 quality management documentation.

The surface-winding unit employs automatic tension control with dancer roller feedback to prevent air entrapment, edge creasing, and telescoping — common quality defects that render PVC membrane rolls unusable or require costly re-winding. The system produces neatly wound rolls up to 30 meters in length with roll diameters up to 1,200 mm, ready for direct palletizing and shipment to roofing installation sites.
A dust-proof enclosure with HEPA-filtered positive air pressure surrounds the winding area, ensuring the membrane surface remains free of particulate contamination. Clean roll surfaces are non-negotiable for hot-air weld integrity during field installation — any dust or debris trapped between membrane laps creates leak paths that compromise the waterproofing system’s long-term performance.

H3: PVC Waterproof Membrane for Single-Ply Commercial Roofing — Fully Adhered, Mechanically Attached & Ballasted
Alt: PVC single-ply waterproof membrane installation on commercial flat roof — mechanically attached system
PVC waterproof membranes are the dominant single-ply roofing material in the European commercial construction market and rapidly gaining share in North America, Middle East, and Asia. The Jwell extrusion line produces membranes compliant with ASTM D-4434 Type III and EN 13707 specifications for fully adhered, mechanically attached, and ballasted roofing installations on office buildings, warehouses, shopping centers, logistics hubs, and industrial facilities.
The PVC membrane’s hot-air weldability creates monolithic, watertight seams that maintain integrity for 30+ years — a performance characteristic that TPO and EPDM competitors continue to pursue. With growing commercial construction in developing economies and increasing retrofit demand in mature markets, PVC roofing membrane demand is sustaining 5-7% annual global growth.
H3: Bridge Deck & Parking Structure Waterproofing Membrane — AASHTO M-286 Compliant
Alt: PVC waterproofing membrane applied to bridge deck surface — traffic-rated waterproofing system
PVC waterproof membranes serve as a critical protective barrier on bridge decks, parking structures, and plaza decks where the membrane must withstand direct vehicular traffic loading, thermal cycling, freeze-thaw conditions, and exposure to de-icing chemicals. The reinforced PVC membrane variant produced on the Jwell line meets AASHTO M-286 requirements for bridge deck waterproofing, with elongation properties exceeding 250% that accommodate the flexural movements inherent in bridge structures under traffic loads and temperature fluctuations.
The membrane’s chemical resistance to chlorides and sulfates provides decades of protection for the structural concrete and steel reinforcement beneath, directly extending infrastructure service life — a priority for government transportation agencies managing bridge maintenance budgets.
We recommend PVC roofing-grade compounds with K-value between 65 and 72, plasticizer content of 25-35 PHR, and calcium-zinc or organotin stabilizer systems. Leading international compound suppliers include Axxaris and Renolit. Our process engineers can help optimize your formulation for specific climate zones — for example, higher plasticizer content and low-temperature impact modifiers for Nordic applications, or enhanced UV absorber packages for desert climates with high solar radiation exposure.
Yes. The precision reinforcement embedding station places polyester scrim or glass fiber mesh (80 to 250 g/m²) between the upper and lower PVC layers during extrusion with ±2 mm positioning accuracy. The photoelectric edge guide sensor ensures the reinforcement remains centered within the sheet, preventing edge exposure. This produces reinforced membranes meeting EN 13707 tear strength exceeding 400 N — the industry benchmark for mechanically attached single-ply roofing installations.
Standard configuration delivers 300-600 kg/h for sheet widths 1,000-2,500 mm and thickness 1.0-2.5 mm. For high-volume manufacturers producing reinforced roofing membrane for export markets, Jwell can engineer higher-output configurations up to 1,200 kg/h, leveraging the same conical twin-screw extrusion platform validated in our 8.5-meter extra-wide geomembrane line — the first domestically produced line of its width in China.
An online beta-ray or laser thickness scanner traverses the sheet continuously, feeding real-time measurement data to the Siemens S7-1200 PLC. The closed-loop system automatically adjusts haul-off speed and die lip restrictor bar position to maintain target thickness within ±0.03 mm. All thickness data is logged at configurable intervals for production traceability. Consistent membrane weight per square meter is the single most critical commercial parameter — it directly determines roofing contractor material cost per project.
Yes. Jwell manufactures complete extrusion lines for the full waterproofing membrane product spectrum: PVC, TPO, CPE, and PE waterproof membranes (PE lines up to 8,000 mm width are available), plus PE drainage board and small-scale testing extrusion lines for R&D. Our 8.5-meter extra-wide geomembrane/waterproof line was the first domestically produced line of its width in China. This breadth of product capability makes Jwell a single-source equipment partner for waterproofing manufacturers expanding across multiple membrane technologies.
