Hoonly Aluminium - Aluminium Extrusion Profiles & Accessories Supplier

Aluminium profiles are aluminium materials with different cross-section shapes through hot melt and extrusion. The production process of aluminium profiles mainly consists of three processes: melting, extrusion and colouring (including oxidation, electrophoretic coating, fluorine spraying, powder spraying, etc.). The aluminium profiles are divided into: 1. Industrial aluminium profile: mainly used for aeroplanes, trains, industrial radiators, automobiles, electrical appliances, etc. 2. Aluminum alloy profile for building: mainly used for building doors and Windows, curtain walls, indoor and outdoor decoration and architectural structure. Surface treatments are divided into: 1. Anodized aluminium: the surface of the profile is oxidized by anodic oxidation, electrolytic colouring or organic colouring. 2. Electrophoresis coating aluminium: the surface of the profile is combined with anodic oxidation and electrophoresis. 3. Powder spraying aluminium: the surface of the pr...

The non-ferrous metal of aluminum is a light, soft, easy to oxidation in air, so people come up with a way, it is aluminum oxidation process, in its outer grow a protective film, durable, and can be dyed colorful color, the feast for the eyes. Anodising, or anodic oxidation, is an electrolytic process that deposits a chemically stable oxide layer on the surface of the aluminum. The resultant oxide film is thicker and stronger than aluminum's natural oxide covering.The principle of aluminum anodes is a process of decorating and protecting the aluminum and its alloys. In the process of alumina film is formed on aluminum made by direct current under enough voltage through a suitable sulfuric acid electrolyte, the object is the aluminum anode, and by another material or special graphite sheet (lead) as the cathode, electrify time grew out of the required thickness of oxide film. After the production of the film, except for some aluminum, the next step is to tint. In general, the...

We talked about two factors that affect the quality of oxide film: Electric Current Density and Temperature , now, we talk about the third factor -- Time. Under the same conditions of solution concentration and other processing technology, with the extension of anodic oxidation time, the generated oxide film will also be gradually thickening (within a certain range), the aperture gap (or pore space) will increase too which is good for dyeing. Under the same process conditions, on the contrary, if the anodic oxidation time is shortened, the generated oxide film will be thin, and the aperture gap (or pore space) becomes less and has trouble dyeing dark. Most of aluminium manufacturers’ anodic oxidation time is less than 20 minutes; except for some special situation, electrochemical polishing (Click on the link to learn more about electrochemical polishing) for example, shortens the anodic time to maintain brightness after anodizing. It’s necessary to extend the anodic time when ...
