Aluminum alloy advertising frame profile production should include casting, extrusion and coloring (coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, wood grain transfer) three processes.
1. Casting is the first process of aluminum alloy advertising frame profile.The main process is
(1) Ingredients: Calculate the additive amount of each alloy according to the specific alloy brand to be produced, and reasonably match various raw materials.
(2) Smelting: The prepared raw materials are added to the melting furnace according to the process requirements to melt, and the impurities and gases in the melting body are effectively removed by means of degassing and deslagging refining.
(3) Casting: Under certain casting process conditions, the molten aluminum is cooled and cast into round casting bars of various specifications through deep well casting system.
2, extrusion: extrusion is the means of profile forming.According to the section design of the profile product, the mould is made, and the heated round casting rod is extruded from the mould by the extruder.The commonly used grade 6063 alloy also USES an air-cooled quenching process and the artificial aging process after the extrusion to complete the heat treatment strengthening.Different grades of heat-treatable strengthened alloys have different heat treatment methods
3, color (mainly about the process of oxidation) oxidation: extrusion good aluminum alloy profile, the surface corrosion resistance is not strong, must be anodic oxidation surface treatment to increase the corrosion resistance, wear resistance and appearance of the aluminum.

4. The main process of aluminum alloy advertising frame profile is as follows:
(1) Surface pretreatment: Clean the surface of the profile by chemical or physical methods, exposing the pure matrix, in order to obtain a complete and compact artificial oxide film.Mirror or matte (matte) surfaces can also be mechanically obtained.
(2) Anodic oxidation: Under certain technological conditions, anodic oxidation occurs on the surface of the pretreated profiles, generating a compact, porous, strong adsorption AL203 film.
(3) Hole sealing: The pores and pores of the porous oxide film formed after anodic oxidation are closed to enhance the anti-pollution, anti-corrosion and anti-wear properties of the oxide film.Oxidation film is colorless transparent, using the strong adsorbability of the oxidation film before sealing the hole, adsorption and deposition of some metal salt in the film hole, can make the appearance of the profile color (silver white) other than many colors, such as: black, bronze, gold and stainless steel color.
