What are the processing processes of aluminum profiles?

Essai Industries Co.,Ltd | Updated: Jun 15, 2017

Extrusion is a means of forming a profile. First, according to the Profile product section design, manufacture the mold, using the extrusion machine will be heated round cast rod from the mold extrusion forming. The commonly used grade 6063 alloy, in the extrusion, also uses a air-cooled quenching process and subsequent artificial aging process to complete the heat treatment enhancement. Different grades of heat treatment hardening alloy, its heat treatment system is different.

To paint (the process of oxidation in the first place)
Oxidation: Extruded aluminum alloy profile, its surface corrosion resistance is not strong, must be treated by anodic oxidation surface treatment to increase aluminum corrosion resistance, wear resistance and appearance of the aesthetic.
The main process is:
(1) Surface pretreatment: Using chemical or physical methods to clean the surface of the profile, exposing the pure matrix, in order to obtain a complete, dense artificial oxide film. A mirror or matte surface can also be obtained by mechanical means.
(2) Anodic oxidation: The surface pretreatment of the profile, in a certain process conditions, the substrate surface anodic oxidation, a layer of dense, porous, strong adsorption of $literal film layer.
Abrasive fabric Aluminum Profile: Matte aluminum to avoid the bright aluminum alloy profiles in the architectural decoration of a certain environment, conditions will form the light of the shortcomings of the interference, its surface as delicate and soft as brocade, is favored by the market, but the existing abrasive material must overcome the surface sand grains uneven, and can see the lack of pattern.
Multi-tone surface treatment of aluminum profiles: drab silver and brown can not meet the architects and external wall decoration tiles, the outer wall latex very good cooperation, the new stainless steel color, the champagne color, the golden yellow, the titanium gold, the Red series (wine red, the JuJube red, the Black, the purple) and so on add the colored glass to make the decoration effect icing on the cake. These profiles must be chemically or mechanically polished after oxidation, the effect is good.
Electrophoresis Coated aluminum Profiles: electrophoretic paint surface gloss Soft, can resist the erosion of cement, mortar acid rain, 90% of Japan's aluminum profiles are electrophoretic paint.
Powder Electrostatic Spraying Aluminum profile: Powder Electrostatic spraying profile is characterized by excellent corrosion resistance, acid and alkali salt mist is much better than oxidized coloring profiles.
Plasma-enhanced electrochemical surface Ceramic aluminum profiles: This kind of profile is the most advanced processing technology in the world today. This profile product quality is good, but the cost is higher. It has more than 20 kinds of hue, its biggest characteristic is can according to need like Calico printing, profile surface color colorful, decorative effect is excellent.
