(1) Slotting: When slotting machine or gongs machine is slotted, the milling cutter with semicircular head is greater than 90 °. The knife should not be too deep injury and aluminum plate, also do not too shallow to make the hem difficult, should leave 0.2-0.3MM thick plastic core material together with aluminum plate bending edge, to increase strength and toughness, otherwise at the bending edge of the aluminum plate may break or paint film burst. (2) ARC Processing: processing arc should use special bending equipment processing, slowly force, so that the plate gradually reached the required surface, do not bend the molding. (3) Installation direction: the same color aluminum plate installed in the same plane, the flow direction should be consistent, otherwise, may create visual chromatic aberration. (4) Conditions of use: internal wall panels should be used indoors, should not be installed outdoors to ensure the use of effects and service life. (5) Tear film: should be in the aluminum plate after the installation of 45 days to tear to protect the film, otherwise it may be difficult to tear film or transfer phenomenon. (6) Batch: the same model and different batches of plates may be chromatic aberration, the sale and use of different batches of the plate should be increased than the color difference procedures, our company mainly engaged in aluminum alloy plate, aluminum pattern plate, etc., no visual chromatic aberration can be used in the same plane. (7) Handling: The plate should be lifted at the same time, no push pull, extraction, so as not to scratch the plate surface. (8) Storage: alloy plate should be stored in dry and ventilated place, and flat on the flat surface, do not trample, impact.
