This sandwich panel line is mainly composed of roll forming machine, cutting unit. With the simultaneously polyurethane foaming, this production line is able to realize the continuous sandwich panel production, length to cut by PLC control, speed control by inverter, and polyurethane panel solidifying process is completed in the double-chain laminator. This production line, with the high production rate and automation, accurate synchronization, is extremely appropriate for polyurethane sandwich panel production in a large scale, which is prior in constructing high quality large-size buildings.
