Automatic Line Production for Sandwich PUR PIR SIP Sandwich Panels Construction Material Making Machinery
This production line is engineered for the continuous manufacturing of rock wool (mineral wool) sandwich panels, primarily utilized in industrial construction requiring stringent fire-safety ratings. The system integrates decoiling, cold-roll forming, rock wool strip flipping, automated adhesive application, and high-temperature curing to ensure structural integrity and thermal consistency across large-scale production runs.
The sandwich panels are widely used for steel structure workshops, roofs of simple and easy movable houses, wall bodies, suspended ceilings of air purification rooms, and separation. Rigid polyurethane foam has been recognized as the best building thermal insulation material internationally. It features low heat conductivity, high bending resistance capacity, water resistance, and protection against insects and mice. With excellent fire resistance and a wide scope of heat resistance, our unique prescription combines high-temperature polyurethane with coating steel panels to achieve compact forming.
