Foam Insulation Board Extrusion (XPS Extrusion) Lines

Sunwell Global is a leading manufacturer of XPS Foam Board Extrusion Lines and XPS Extruders, providing advanced solutions for high-quality foam insulation board production. Our tandem foam board extrusion lines are designed for efficient and consistent XPS foam board manufacturing, utilizing CO2 as a blowing agent for environmentally friendly production.

• High Production Capacity: With output capacities ranging from 250 kg/h to 1200 kg/h, our XPS Foam Board Extrusion Lines can produce board thicknesses from 20mm to 200mm and widths from 600mm to 1200mm, meeting diverse market demands.
• Automated Raw Material Handling: Up to 8 raw materials, including flame retardants and nucleating agents, are automatically loaded and blended for a uniform melt. This ensures consistent quality and optimal processing in the primary XPS extruder.
• Precision Blowing Agent Control: CO2, plasticizers, and/or HFC blowing agents are precisely metered using triple-head ATEX-compliant diaphragm pumps with mass flow measurement, ensuring stable foam density and superior board quality.
• Advanced Extrusion Technology: The secondary XPS extruder features a high mixing, low shear screw with a water-cooled bimetallic barrel and motorized valve control to minimize temperature variations. A static mixer and homogenizing tube ensure a uniform melt before entering the chrome-plated flat XPS die, which includes quick opening, fine-tune adjustment bolts, and Teflon guide shoes.
• Efficient Calibration and Cutting Systems: The board calibrator with temperature-controlled plates and robust haul-off system withstands CO2 expansion pressures and includes a fail-safe pneumatic quick opening mechanism. Travel conveyors allow for controlled cooling before edge milling and precise length cutting by a double-blade cross cutter designed for high-speed production.
• Customizable Surface Finishing: Boards can be planed or grooved to meet specific market requirements. After further cooling, edges can be milled into flat surfaces, tongue and groove, or shiplap profiles.
• Fully Automated Stacking and Wrapping: Sunwell Global offers fully automatic board stacking and six-sided product wrapping, with optional features like product printing, soundproofing, and dust extraction for a complete production solution.
