The PC Hollow Sheet/U-shaped/U Locked Sheet Extrusion Line is a specialized production line designed for manufacturing polycarbonate (PC) hollow sheets, U-shaped profiles, and interlocking (locked) sheets. These sheets are widely used in construction (e.g., skylights, noise barriers), advertising (lightboxes), agriculture (greenhouse covers), and industrial protection due to their lightweight, high strength, weather resistance, and light transmission properties.
The production line typically includes:
Extruder: Single or twin-screw design, optimized for PC material processing (melting temperature: 250-300°C).
T-die: Flat extrusion die to form sheets with adjustable thickness/width.
Calibration Unit:
Vacuum calibration table: Ensures precise shaping of hollow/U-shaped/locked structures.
Cooling system: Water or air cooling to prevent deformation.
Haul-off unit: Controls sheet speed and tension.
Cutting machine: Precision cutting (saw or laser).
Stacker: Automated sheet collection.
Multi-layer co-extrusion: Produces 2/3-layer composite sheets for enhanced insulation/soundproofing.
High-precision control: PLC/computerized system for temperature, pressure, and speed adjustment.
Versatility:
Processes solid PC sheets, hollow sheets, U-shaped/locked profiles.
Thickness range: 2mm-16mm (hollow sheets up to 10mm, multi-layer up to 16mm).
Energy efficiency: Melt pump options reduce power consumption.
