Sandwich Panel Line

A PU sandwich panel production line is an automated system designed to produce polyurethane (PU) insulated sandwich panels, widely used in cold storage, industrial buildings, and energy-saving construction. These panels consist of two metal facings—usually galvanized steel or aluminum—with a rigid PU foam core for insulation. The PU sandwich panel production line offers high production efficiency, excellent thermal insulation, and strong structural performance. It is ideal for businesses seeking to mass-produce lightweight, durable, and energy-efficient building panels. With low labor needs and high output, it delivers excellent value and adaptability for modern construction demands.
