Every single test. ( 2) Immersion test: the effect of the sample in the normal temperature water soak about 1 hours later, the film layer and transfer are not isolated, explain laminating film layer is strong. A test every month. 3, nameplate paste performance test ( 1) Actually use the heating test, machine is in actual use condition, waiting for the machine temperature, to 15 minutes, Or to reach thermal equilibrium) After checking the paste nameplate. Nameplate should paste is good, no case become warped, edge or other defects. Normal with finger push nameplate, displacement is not greater than 1 mm. For each pick up samples. ( 2) Freezing test, the bearing plate of the surface of the machine in the - 5 ~ 30 minutes 0 ℃ environment, film layer and transfer are not isolated, nameplate and machine surface are not isolated, there is no warping, edge phenomenon that paste firmly. Each quarter test a, general appropriate mail company test. ( 3) Water immersion test, the test only for series products and work surface easily when in contact with water. Will attached nameplate of the surface of the machine into cold water soak for 30 minutes, membrane layer and transfer are not isolated, nameplate and machine surface are not isolated, no warping, edge phenomenon that paste firmly. Every single test. Introduced above is printing nameplate label inspection method, the current produced nameplate material has a lot of, such as zinc alloy, copper, iron, aluminum, plastic, acrylic, organic board, etc. , but mainly in aluminum production is more, as the nameplate processing effect relative to high-grade, durable, no rust, also favored by many consumers.
