In life, our aluminum alloy signs are applied everywhere, such as: flowers and plants, tree brands, office cards, but many people do not know much about their process, let's take a look at the aluminum alloy sign making process together with the small plait: first, machine molding, painting after machining molding, so that its installation size is uniform and standardized and can be mass produced. The processing of the paint panel of the instrument has strict requirements on the size, requiring experienced tongs and milling workers, and CNC drilling machines can be used if conditions permit. Second, oil removal identification in order to make the surface of the aluminum plate have certain affinity with the printing coating, the oil stain on the surface of the plate should be removed. Generally, the oil stain on the package can be wiped off with fine soft sawdust first, and then oiled with organic solvent; Oil stains in machining can be chemically deoiled with organic solvent or alkaline solution. Three, polishing, plate surface scratches, should first wipe a layer of putty to make it smooth, and according to customer requirements to choose mechanical polishing, chemical polishing, or electrochemical polishing. Four, spray primer due to the poor combination of aluminum alloy material and finish paint, printing ink, before spraying finish paint on aluminum alloy panel need to spray a layer of about 0. 01mm thick epoxy zinc yellow primer. Five, spray paint according to customer requirements, spray the corresponding color of amino paint or acrylic paint. For light color paint, especially white paint, the drying temperature and drying time should be strictly controlled, otherwise the white paint will turn yellow. Six, screen printing, printing Signage Panel overall requirements are: accurate and clear graphic position, neat word line edge, wordy and firm. Seven, screen, according to the thickness of the font line to choose different mesh screen. The commonly used silk screens are 250 T, 300 T, 350T and 420S polyester silk screens. For word diameter less than 1. 5mm should choose monofilament yellow polyester mesh larger than 350 mesh. The angle of the net. The angle of the net is 22. At 5 °, the ink area under the word line can be large and the edge of the word line is neat. Eight, scraper scraper should be flat tip, Shore hardness in 65-At 70 o'clock, ensure line contact during printing. The scraper of the label panel should be dedicated. Net distance. Large screen tension and small screen distance are conducive to printing the figure. When the screen tension is determined, the screen distance should be controlled at 2-3mm. Nine, printing ink red panel paint drying to low temperature and short time. Ten, spray finish paint requirements are not high can be brushed, paint can be H-type water-soluble acrylic paint or amino paint. Eleven, packaging, signs due to the heavy plate, easy to bump between each other, can be placed in the finished product without graphic old paper to protect its surface.
