Energy Saving PU Sandwich Panel Machine

The energy-saving pu sandwich panel machine is an automated system designed specifically for producing high-performance building enclosure panels, integrating material processing, foam molding, composite pressing, and finished product cutting processes. The pu sandwich panel produced by the energy-saving polyurethane sandwich panel production line is composed of two layers of metal panels (usually color steel plate, stainless steel or aluminum plate) and the polyurethane rigid foam core in the middle, which has excellent thermal insulation performance, high strength to weight ratio and fast installation characteristics.
