1. The machine does not start: the input wire is disconnected, the power cord is reversed, and the voltage is insufficient.
        Second, the temperature measurement is not accurate: thermocouple, temperature controller. Whether it is installed incorrectly and damaged.
        3. The working vacuum does not come up: the gas path is blocked, the hand valve or the solenoid valve is not closed, the vacuum pump motor belt is loose, and the vacuum gauge is damaged.
        4. The main power switch trips: leakage of the input wire on the top of the heating box, leakage of the distribution box, external wires on the equipment, leakage of the motor, etc.
        Fifth, the suction film is not in place: the vacuum is not enough, the air leakage, the temperature is not enough, the film is too thin, the workpiece is pasted with other materials, the concave depth of the workpiece exceeds the lift of the film, the suction time is too short, the film is not lifted, the distance between the workpiece Too close.
        Sixth, the surface of the overlaid workpiece is folded and not smooth or the corners cannot be wrapped: the film is not straightened, the quality of the film is not good, the workpiece is not well polished, the glue is sprayed too much, and the mold below the workpiece is too low.
       7. When the laminating machine does not reach the suction, the film is pulled down: whether the solenoid valve or the hand valve is open.

       8. Breaking phenomenon: the temperature is too high, the heating time is too long, the film quality is not good, and there is no heating.
