Pu Sandwich Panel Production Line - 24m Double Conveyor

PU (Polyurethane) sandwich panel production line is a specialized manufacturing setup designed to produce sandwich panels that consist of an insulating core made of polyurethane foam sandwiched between two outer layers, typically made of metal or other materials. These panels are widely used in construction for walls, roofs, and cold storage facilities due to their excellent thermal insulation properties, lightweight nature, and ease of installation.
