Quality standard after laminating machine printing:
        1. The color of the printed pattern remains unchanged, and it will not change color under the sun, baking and ultraviolet radiation.
        2. The film is firmly bonded, the film layer cannot be easily separated, the surface is clean and smooth, not blurry, good finish, no wrinkles and powder foil marks. Any wrinkles and creases are considered unqualified products.
        3. The film-covered product must not be curled, the size after division is accurate, the edges are flat and smooth, and no film or film loss can occur. The break is no more than 4㎜.
        4. The degree of drying after coating is appropriate without sticking to the surface. On thick solid and dark areas of the ink, there should be no sand bumps, stripes, or worm-like film bumps.
        5. After the film is placed for 10-20 hours, there is no change in product quality.
        Extending the life of the laminating machine is mainly for the maintenance of the motor when using it. The main points to pay attention to are the following:
        1. Clean up debris, dirt on the motor, nearby debris, and stay away from flammable and explosive materials.
        2. Before starting, you should check whether the machine rotates smoothly, whether it is blocked, and whether the belt connection is normal; if there is any abnormality, you should never continue to start the glue machine.
        3. The voltage at start-up should meet the rated voltage; the general voltage value is about 5 to 10 percent of the rated voltage value.
        4. After the motor fails, you must cut off the power supply and can not continue to use; you should find a professional to repair.

        As long as the life of the laminator is maintained, correct operation, maintenance, and maintenance; other parts also need to be well maintained; careful maintenance and maintenance are a good way to extend the life of the machine.
