1. Overview
A plastic sheet/board production line is an integrated extrusion system that converts thermoplastic pellets (PE, PP, PVC, ABS, PS, etc.) into continuous flat sheets or thick boards. The line is widely used in packaging, construction, automotive, advertising, and chemical industries because it can deliver widths from 300 mm up to 2 200 mm and thicknesses from 0.2 mm up to 60 mm in a single pass.
2. Core Process Steps
• Material Preparation – Resins, fillers, stabilizers and colorants are pre-mixed in a high-speed mixer or gravimetric feeder.
• Melting & Plasticising – A single-screw or conical twin-screw extruder melts, homogenises and meters the polymer melt at precisely controlled temperature and pressure.
• Sheet Formation – The melt is pushed through a flat T-die to form a continuous sheet of target width and thickness.
• Calibration & Cooling – A vacuum calibration table and a series of chill rolls rapidly cool and size the sheet to final dimensions while minimising internal stress.
• Haul-off & Cutting – Servo-driven haul-off units maintain constant tension; a flying cut-off saw or guillotine cuts the sheet to length.
• Stacking or Winding – Finished sheets are automatically stacked or coiled for downstream handling.
3. Typical Line Configuration
1) Extruder: single-screw (PE/PP/PS/ABS) or conical twin-screw (PVC)
2) Hydraulic screen changer for continuous filtration
3) Melt pump (optional) for gauge uniformity
4) Flat T-die with flex-lip adjustment
5) Three-roll calender or vertical chill-roll stack
6) Edge-trimming and on-line crusher for recycling edge trim
7) Dual-station winder or automatic stacking table
8) PLC/SCADA control system with recipe management and remote diagnostics
4. Key Technical Parameters (example for thick board line)
| Model | Raw Material | Board Width | Board Thickness | Max. Output | Main Motor |
|-------|--------------|-------------|-----------------|-------------|------------|
| SJ-120 | PE/PP/ABS | 1 220–1 600 mm | 10–40 mm | 400 kg/h | 132 kW |
| SJSZ-92/188 | PVC | 1 200–2 000 mm | 10–30 mm | 600 kg/h | 110 kW |
5. Advantages of Modern Lines
• High-output screws designed for up to 70 % CaCO₃ or recycled content
• Quick-change die lips and roll-gap positioning for fast product change-over
• Closed-loop thickness gauge (X-ray or infrared) for ±2 % tolerance
• Energy-efficient AC motors + ABB/Siemens drives
• Turn-key service: plant layout, utilities, formulation, commissioning, operator training, and 12–18 month warranty.
6. Applications
• Rigid PVC boards: chemical tanks, laboratory bench tops, advertising signs
• PP/PE boards: food cutting boards, plating barrels, light-duty machine guards
• ABS/PS sheets: refrigerator liners, automotive interior panels, luggage shells.
With robust mechanical design, intelligent control, and comprehensive after-sales support, a modern plastic sheet/board extrusion line offers an economical route to high-quality, large-volume flat plastic products.
