PVC Sheet & Profile Extrusion Line
Modular PVC Sheet & Profile Extrusion Line with twin-screw extruder, T-die & 3-roll stack, vacuum calibration table, in-line thickness/OD control, and PLC/HMI automation.
Overview
The PVC Sheet & Profile Extrusion Line is a compact, modular platform for rigid PVC sheets (signage, thermoforming, protection) and custom PVC profiles (doors/windows, conduits, trims, cable trunking). It combines a conical/parallel twin-screw extruder, precision T-die or profile die, vacuum calibration table/box, 3-roll polishing stack or long cooling beds, synchronized haul-off, and guillotine/flying-saw/chipless cutting. With PLC/HMI automation and optional in-line thickness/OD gauges, the line delivers flatness, gloss, dimensional accuracy, and low scrap at optimized kWh/kg.
Key Features & Benefits
-
Twin-screw plastication for PVC: stable melt, low gel, excellent fusion for uPVC/CPVC formulas.
-
Sheet & profile flexibility: quick swap between T-die + 3-roll stack (sheet) and vacuum calibrators (profile).
-
Precision & consistency: in-line thickness gauge / OD measurement with closed-loop control.
-
Clean edges & smooth surfaces: edge trim & re-feed for sheet; long calibrator beds for profile straightness.
-
Energy-saving design: insulated heaters, VFD/servo drives, closed-loop water and filtration/UV.
-
Smart operation: PLC + touchscreen HMI, recipe library, alarms, production & energy data export.
Typical Applications
-
Rigid PVC sheets: display/advertising, thermoforming trays, luggage, protection board.
-
Profiles: window/door frames, skirting, cable trunking, corner guards, conduits, decorative trims.
-
Optional foam board / co-extruded cap layers (upon tooling and formulation review).
Technical Specifications (customizable)
| Item | Sheet Line (typical) | Profile Line (typical) |
|---|---|---|
| Material | uPVC / CPVC | uPVC / CPVC |
| Width / Section | Sheet width 600–1,220 mm | Sections ≤ 250×120 mm (larger on request) |
| Thickness / OD | 0.3–6.0 mm rigid sheet | Wall 1.2–6.0 mm, per drawing |
| Throughput | 220–500 kg/h (die & roll size dependent) | 120–300 kg/h (tooling dependent) |
| Line Speed | 3–20 m/min | 2–15 m/min |
| Gauging (opt.) | In-line thickness scanner | Laser OD / profile dimension cameras |
| Control | PLC + 7″/10″ HMI, data export | PLC + 7″/10″ HMI, data export |
Final performance depends on resin (stabilizer/filler), tooling, cooling capacity, and target standard (e.g., EN/ASTM).

Process Flow
Feeding & dry-blend → Twin-screw plastication → T-die / Profile die → 3-roll stack (sheet) or vacuum calibration table/box (profile) → Multi-stage cooling → Servo haul-off → Guillotine/Flying-saw/Chipless cutting → In-line gauging & SPC → Edge trim (sheet) / Run-out (profile) → Stacking/packing
Customer Case
FAQ
Q1: Can one line handle both sheets and profiles?
Yes—using modular tooling: T-die + 3-roll stack for sheet, profile die + vacuum calibrators for profiles.
Q2: Do you offer in-line thickness/OD control?
Yes—sheet thickness scanners or laser/profile cameras with closed-loop control to stabilize dimensions.
Q3: What about edge trimming and re-use?
Sheet edges can be trimmed and re-fed via a grinder/feeder loop to reduce waste.
