Brief Introduction for Aluminium eyewear anodizing production process

  By Topview Eyewear. Published on Sep 03, 2017

The production process for aluminum eyewear anodizing surface treatment mainly include these steps: cleaning, anodizing, dyeing, sealing, assembling, etc. After anodizing surface treatment, the aluminium eyewear have beautiful and bright color; its corrosion resistance, wear resistance and insulation is better than other aluminum products. The aluminium eyewear hanging in a specific electrolyte solution are used as an anode for electrolysis. During the electrolysis process, the hydroxide ions in the water emit electrons and turn into water and new ecological oxygen in anode, which oxidizes the aluminium into a thicker alumina film. This process is the oxidation of the metal product as an anode, so it is called anode Oxidation. By anodizing, dyeing and sealing treatment, the original aluminium eyewear become dyed products.

The first step for Aluminium eyewear anodizing process : clean the aluminium eye frames.

During the manufacturing processing, Aluminium eye frames stained with much grease and some abrasive, so it needs to do pre-treatment. Put the aluminium eye frames into the specialized chemical solution for cleaning.

The second step for Aluminium eyewear anodizing process: anodizing treatment.  

Immerse the aluminium eye frames to be dyed in the electrolyte and then turn on the power; After all the specified operation is completed, take the aluminium eye frames out from the electrolyte and rinse the acid liquor adhering on the aluminium eye frames with clear water.

The third step for aluminium eyewear anodizing process: dyeing operation.

Soak the anodized and washed aluminium eye frames in the 40-60 degrees of coloring solution immediately. After a predetermined time, rinse the aluminium eyewear with clear water.   

The forth step for Aluminium eyewear anodizing process: sealing.   

Put the dyed and cleaned aluminium eyewear into the clear water with 90-100 degrees and then boil them for 30 minutes. After this process, the surface of the aluminium frames become uniform and non-porous, forming a dense oxide film. The dye is deposited in the oxide film and can not be erased any more. The oxide film is wear-resisting, temperature resistance and corrosion resistance.

The fifth step for Aluminium eyewear anodizing process: wiping and assembling

Dry the aluminium eyewerar after sealing process and polish with a soft cloth, then you can get a beautiful and bright aluminium frame; after the final assembly process, such as assemble the lenses, a complete pair of aluminium eyewear is finished.

The above is only a brief introduction of anodizing treatment for alumminium eye frames and aluminium sunglasses. In production, it is much more complicated than the above description, such as each process is requried to be perfect; each process has some defect products and then we pick them out; only the qualified products enter into the next production process. Compared with the coloring process plating or spraying for other glasses, anodizing treatment for aluminium eyewear leads to a larger production loss. Defect products from plating or spraying prodution process can be picked out and repeat this process, but the rejected products from anodizing treatment process would only be discarded. That is the reason why high quality aluninium eye frames or aluminium sunglasses is more expensive than normal acetate eyewear. But because aluminum material itself is not so expensive, the price of aluminium eyewear can be accepted by most customers. General speaking, aluminium eyewear is a little expensive than acetate eyewear and ordinary metal eyewear, but it is cheaper than titanium glasses, carbon fiber glasses, buffalo horn eyewear, and wood glasses.  

Aluminium eyewear and aluminium sunglasses are one of the most competitive products of Topview Eyewear.
