ISO9001: 2008 Certified PE PP Sheet Extrusion Line with Single-Screw Extruder and Three Rolls Calender

This advanced extrusion line consists of SBJZ-series plate & sheet special-purpose single screw extruder, SJZ-series conical twin screw extruder, or SJ-series parallel twin screw extruder. When equipped with auxiliary downstream accessories and molds, it can produce various materials including PP, PS, HIPS, PE, ABS, EVA, PMMA, PC, PT, PVB, and PVC boards and sheets.

The complete machinery unit includes:

• Extruder
• Screen changing device
• Melt pump
• T-die
• 3-roller or multiple-roller calender
• Cooling device
• Edge cutter
• Haul-off system
• Plate cutter winder
• Electrical control system

The system operates based on the three states of hot plastics at different temperatures. The pushing force of the screw changes the physical state from glass state to high elastic state, then to glutinous-and-fluid state. The material exits from the slim gap of the die, followed by calendering, cooling-shaping, edge-cutting, haul-off, cutting, and winding processes.

• High-grade alloy structural steel (38CRMOALA) material barrel, screw, and mold with nitriding treatment for high hardness, corrosion resistance, and long service life
• Specially designed T-die flow passage for easy material flow without detaining, ensuring even product thickness
• Calender with large conical slot design for optimal cooling quality inside the roller and temperature synchronization

The system can produce various products including PC/PP hollow cross-section plate, PVC transparent soft & hard plate & sheet, PVC foamed plate, PMMA/ABS co-extrusion bathing plate, inside chamber plate of the refrigerator, and other multiple-layer composite co-extrusion plates and sheets.

Specifications:

• Width: 300MM-700MM
• Thickness: 0.2MM-45MM
• Output rate: 80-1800KG/H
