The XINNUO EPS Sandwich Panel Continuous Production Line is a fully automated, high-efficiency production system designed for manufacturing roof and wall panels. Using expanded polystyrene (EPS) as the insulation core, the line produces panels with beautiful, precise, and diverse cross-sectional shapes. EPS is a white, lightweight material with excellent waterproofing, thermal insulation, soundproofing, and buffering properties.
Integrating international advanced technologies, Xinnuo EPS production lines are durable, easy to operate and maintain, stable in performance, and cost-effective. The equipment has been exported to Asia, the Middle East, and Central & South America, receiving high praise from customers.
Stable feeding of steel coils into the upper and lower layers of sandwich panels
Hydraulic mandrel type for automatic operation, convenient control, and precise performance
2+2 Un-coiler system allows coil replacement without stopping the line, ensuring continuous high-capacity production
Continuously shapes the steel coil into wall or roof panel profiles
Cassette-type and railway wheel design for easy mold replacement
Produces panels with refined, aesthetic profiles
General Joint Type: standard supply system, delivers two EPS boards in zigzag pattern
Finger Joint Type: designed for thick, rigid panels used in cold storage; continuous feeding through finger joint grooves
Trims panel edges and surfaces according to specifications
Ensures panels are precise and visually appealing
Evenly applies adhesive to bond steel sheets and EPS core
Two options:
Mixing Type: cost-effective, durable, globally widely used
Spray Type: slightly more expensive, reduces adhesive waste and usage
Applies constant pressure and heat to form the sandwich panel
Features patented rubber roller laminating system, which is energy-efficient, low-cost, and ensures panel flatness
Cuts laminated panels to customer-specified lengths using band saw
Optional wheel or band saw cutting to meet different requirements
Automatically stacks finished panels according to preset quantity
Roof panels can be cross-stacked if required
Packs stacked panels with plastic wrap (four or six sides) and discharges them
Optional pallet system inserts EPS blocks automatically for easier transport and storage
