Foam Sheet Extrusion Lines

Sunwell foam extrusion systems feature tandem configurations designed for stable, high-output production of EPS, EPE, EPP, XPET, and foamed PLA sheets. These systems are engineered for precise process control, consistent foam structure, and reliable long-term operation, making them ideal for food packaging and disposable container applications.

Advanced Foam Extrusion Technology

Utilizes precise temperature zoning, optimized screw design, and controlled blowing-agent metering—including ATEX-compliant pumping systems—to achieve consistent foam density, fine cell structure, and reduced production defects.

High Output & Energy-Efficient Operation

Designed for high productivity, with output capacities ranging from approximately 220 to 900 kg/hr, and higher upon request depending on material and sheet specifications. Optimized heating, cooling, and automated process control help reduce energy consumption while maintaining stable, high-throughput production.

Multi-Material Compatibility & Production Flexibility

Supports a wide range of foam materials, including EPS, EPE, EPP, XPET, and foamed PLA. The system accommodates sheet thicknesses from 0.5 to 12 mm and a broad density range (EPS: approx. 35–250 kg/m³; EPE: approx. 17–30 kg/m³), allowing flexible production for different applications.

Precise Sheet Thickness & Width Control

Advanced die and extrusion head design ensure excellent dimensional stability and uniform thickness across the sheet width, providing reliable performance for downstream thermoforming and cutting processes.

Integrated Cooling, Haul-Off & Winding Systems

Seamlessly integrated cooling rolls, edge trimming, haul-off units, and automatic winding systems minimize shrinkage, ensure clean roll formation, and support continuous, stable operation.

Robust Industrial Design and Intelligent Automation

Built for continuous 24/7 industrial production, Sunwell systems feature heavy-duty extruder structures, servo-driven downstream equipment, and PLC-based touchscreen controls for easy monitoring and stable process control.

Custom Configurations for Specific Applications

Available in single-layer, multi-layer, or laminated foam sheet configurations, enabling tailored solutions for food-service packaging, protective cushioning, insulation boards, and other specialized applications.
