• Cooling Device: Effectively cools melt while maintaining high efficiency
• Edge Cutter: Precisely trims sheet edges
• Haul-off System: Smoothly pulls the sheet through the process
• Plate Cutter/Winder: Efficiently cuts and winds finished sheets
• Electrical Control System: Ensures automation and efficient operation

The plastic material undergoes three distinct states at different temperatures: The screw's pushing force transforms the material from a glassy state to an elastic state and finally to a viscous, fluid state. The material flows through the narrow gap of the die, followed by calendering, cooling, shaping, edge cutting, haul-off, cutting, and winding processes to produce the finished sheet product.

• High-Strength Alloy Structural Steel: Material barrel, screw, and die constructed from high-grade alloy structural steel (38CRMOALA) treated by nitriding for exceptional hardness, corrosion resistance, and extended service life.
• Advanced T-Die Design: Flow channel engineered for smooth melt flow without stagnation, ensuring uniform sheet thickness distribution.
