The pressing technology for truck body panel

Our truck body panel is fully enclosed composite sandwich structure, the inside and outside surface are the FRP sheet, the thermal insulation layer is rigid polyurethane foam, it is necessary to put into embedded parts, which bonded by glass fiber mat and resin adhesive after hot pressing.The panel structure should be molded without steel structure and cold bridge,the heat preservation performance is good, and with good waterproof performance at the same time, the panel should be high intensity, light weight,it can effectively solve the puzzles of bubble, wrinkles and other technical problems.we require high production efficiency and the production of cars inside and outside surface does not need to spray paint processing.And the surface flatness error should be controlled at 0.5 mm/m or less.
