Product Specification

Molten casting is the first process of aluminum production.

The main process is:

(1) ingredients: according to the specific alloy plate number that needs to be produced, the addition quantity of various alloy components can be calculated and the various raw materials can be reasonably matched.

(2) smelting: it is required to add the raw materials to the melting furnace in the melting furnace, and remove the slag and gases from the melt through the removal of air and slag.

(3) casting: the molten aluminium liquid is cast in a certain casting process, and the casting system is cooled and cast into various specifications.

Squeeze: extrude is a means of forming shapes. According to the section design of the profile product, the mould is made, and the hot round cast rod is extruded from the die by the extruder. The usual plate number 6063 alloy is also used in the extrusion process with a cold quenching process and the subsequent artificial aging process to complete the heat treatment reinforcement. The heat treatment system of different license plate is different.

3, color (here mainly speak first oxidation process) oxide, aluminum profile extrusion good, its surface corrosion resistance is not strong, must through the anodic oxidation surface treatment to increase the corrosion resistance and wear resistance of aluminum and aesthetic appearance. Its main process is:

(1) surface pretreatment: clean the profile surface with chemical or physical methods, and expose the pure matrix to facilitate the obtaining of a complete and compact artificial oxide film. It can also be obtained by means of mechanical means to obtain the surface of a mirror or light.

(2) anodic oxidation: the surface pretreatment of the profile, under certain technological conditions, the substrate surface is oxidized to generate a layer of dense, porous and strongly adsorbent AL203 film layer.

(3) sealing hole: the pores of the porous oxide film formed after anodizing of anodized film are sealed and the oxide film is enhanced by anti-pollution, corrosion resistance and abrasion resistance. Oxide film is colorless, transparent, the use of hole sealing before oxidation film of strong adsorption, in some metal salts adsorption sedimentation of film hole, can make the profiles look outside show ecru (silver) many colors, such as: black, bronze, golden color and stainless steel, etc.
