Before gluing, check the heat sealing and pressing, take off the skin, check whether there is gap on the surface of the glue film, if there is gap, compensate the corresponding glue film until there is no gap, and press it with a hot air gun. At the same time, uniformly punch the plate plate glue film to strengthen the air guiding property between the glue films. Finally, assemble the skin and gantry, punch the vacuum bag into the hot press tank to complete the gluing.
