The production process of aluminum
profiles.
1. Ingredients: according to the specific
production of gold medal number, calculate the addition of various alloy
components, reasonable matching of various raw materials.
2. Melting: the matching raw materials will
be added to the melting furnace according to the process requirements, and
through degassing, slag refining means to effectively remove the residue, gas
in the melting body.
3. Casting: smelting good aluminum liquid
in a certain casting process conditions, through the deep well casting system,
cooling cast into a variety of specifications of round casting rods.
4. Extrusion: extrusion is the means of
profile forming. First according to the profile product section design,
manufacturing mold, the use of extruder will be heated round cast rod from the
mold extruded into shape. Commonly used brand 6063 alloy, in the extrusion also
used the air-cooled quenching process and its later artificial age process, in
order to complete the heat treatment reinforcement. Heat treatment reinforced
alloys of different brands have different heat treatment systems.
5. Coloring (take anodized surface
treatment as a sample) anodized: squeezed aluminum alloy profile, its surface
corrosion resistance is not strong, must be surface treatment through anode
oxidation to increase the corrosion resistance of aluminum, wear resistance and
aesthetic appearance. Its main processes are: (1) surface pre-treatment:
chemical or physical methods to clean the profile surface, exposing a pure
substrate, in order to obtain a complete, dense artificial oxide film. Mirror
or lightless (light) surfaces can also be obtained by mechanical means.
(2) Anodized oxidation: pre-treated
profiles on the surface, under certain process conditions, anode oxidation
occurs on the surface of the substrate, resulting in a dense, porous, strong
adsorption force of the AL203 film layer.
(3) Sealing holes: the membrane pores of
pores of pores generated after anode oxidation are closed, which enhances the
anti-pollution, corrosion and wear resistance of the oxide film. The oxidation
film is colorless and transparent, using the strong adsorption of the oxide
film before sealing the hole, absorbing and depositing some metal salts in the
membrane hole, which can make the profile appear in many colors other than the
natural color (silver white), such as: black, bronze, gold and stainless steel.
