System Components
Extruder: SBJZ series single screw extruder, SJZ series conical twin screw extruder, or SJ series parallel twin screw extruder
Screen Changer: Ensures stable melt flow
Melt Pump: Provides stable melt flow rate
T-Die: Ensures uniform distribution of melt, avoiding stagnation and ensuring even sheet thickness
Three-Roller or Multi-Roller Calender: Ensures sheet flatness
Cooling Device: Effectively cools the melt and maintains high efficiency
Edge Cutter: Precisely cuts sheet edges
Haul-off System: Smoothly pulls the sheet
Plate Cutter/Winder: Efficiently cuts and winds the sheet
Electrical Control System: Ensures automation and efficient operation
Working Principle
The plastic undergoes three states at different temperatures: The screw's pushing force changes the material from a glassy state to an elastic state and then to a viscous, fluid state. It flows out through the narrow gap of the die, after which the processes of calendering, cooling, shaping, edge cutting, haul-off, cutting, and winding take place.
Machine Features
High-Strength Alloy Structural Steel: Material barrel, screw, and die made of high-grade alloy structural steel (38CRMOALA) treated by nitriding, providing high hardness, corrosion resistance, and long service life.
T-Die Design: Flow channel designed for smooth melt flow without detaining, ensuring uniform sheet thickness.
Calendering Design: Large conical slot design enhances cooling inside rollers, ensuring temperature synchronization for high-quality production.
Applicable Materials
The line is designed for producing various plastic sheets and films, including:
PC/PP Hollow Cross-Section Plates
PVC Transparent Soft & Hard Plates and Sheets
PVC Foamed Plates
PMMA/ABS Co-Extrusion Bathing Plates

Product Applications
ABS Sheets: Widely used in refrigerator industry for components like fridge drawers and gallbladders
PS Sheets: Primarily used in semiconductor electronics and computer communications
PE/PP Sheets: Low-density, good sanitation performance, corrosion resistance, and heat resistance, widely used in anti-corrosion materials and container manufacturing
Energy-Saving Design
Water-Cooled Forced Feeding System: Reduces main motor power consumption
Long L/D Ratio and Mixing Head: Ensures perfect gelatinization and high output
T-Die Special Design: Facilitates sensitive thickness adjustment
Intelligent Temperature Control System: Precisely controls roller temperatures, ensuring high-quality and efficient production
