Anodizing is an electrochemical process that can transform the metal surface into decorative,durable, anticorrosion anodic oxide coatings. Anodizing line can overcome deficiencies in surface hardness and wear resistance of materials like aluminum, extending their service life. Aluminum is particularly well-suited for anodizing, and other non-ferrous metals such as magnesium and titanium can also undergo anodization. The produciton ine includes Common anodizing line, Hard anodizing line, Porcelain anodizing line, Chemical anodizing line.
1. Common anodizing line
It is suitable for surface oxidation treatment of large quantity of aluminum pipe workpieces, with intelligent opem program amd fully automatic PLC touch screen operation. The production line can be divided into semi automatic type and fully automatic type.
2. Hard anodizing line
Hard anodizing is called hard anodizing treatment. Hard anodic oxide film generally requires a thickness of 25-150um, most hard anodic oxide flm thickness of 50-80um, film thickness of less than 25um hard anodic oxide flm, used for tooth bond and screw and other parts of use, wear-resistant or insulation with an anodic oxide film thickness of about 50um, in some special process conditions, require the production of thickness of 125um or more hard anodic. However, it must be noted that the thicker the anodic oxide film, the lower the microhardness of the outer layer can be, and the roughness of the film surface increases. The tank solution for hard anodizing is generaly a sulfuric acid solution as well as sulfuric acid with organic acids such as oxalic acid and sulfamic acid. In addition, hard anodizing treatment can be achieved by lowering the anodizing temperature or reducing the sulfuric acid concentration. For deformed aluminum alloys with copper content greater than 5% or silicon content greater than 8%, or pressure casting aluminum alloys with high silicon content, perhaps some special measures for anodizing should also be considered.
3. Porcelain anodizing line:
Porcelain anodizing, also known as imitation and polar oxidation, the obtained aluminum oxide flm is light gray-white, opaque, and similar in appearance to the catch porcelain enamel layer, which can be used for the protection of the surface of various instruments and electronic apparatus parts and the surface decoration of daily necessities and food utensils.
4. Chemical anodizing line
Chemical oxidation does not need to be energized, but only needs to immerse the aluminum profile in the chemical potion to make the aluminum on the surface of the profile undergo oxidation reaction to generate the oxide film.
