Anodized Aluminum Extrusions Capabilities
Otalum offers an in-house anodizing facility and ensures that you get the high-performance anodized aluminum finishing exactly what you need.
Our 2-step aluminium extrusion anodising process delivers an excellent finish that won’t fade for decades. This 2-step anodising process includes mechanical and chemical processes. Mechanical finishes can be achieved by sanding, polishing, buffing, burnishing, or glass bead blasting. The chemical processes include etching, chemical polishing, anodizing and electrophoresis. Based on your specific requirement, Otalum will choose the most proper anodising aluminium process to produce the products with the ideal finishing.
Normally, we offer the choices of clear aluminum anodizing, titanium anodising, brown anodizing and black hard aluminum anodizing. All of the aluminium anodizing processes are available in both clear and electrolytic colours. The thickness of the anodic layer is at least 10 microns and it can be thicker as you wish.
Anodizing Process And Benefits
Anodizing is an electrochemical process that accelerates and thickens the original protective oxide layer. The resulting anodic coating is part of the metal but has a porous structure that allows secondary infusion, such as coloring. Its benefits include:
Increased durability
Lower maintenance costs
Aesthetically pleasing appearance
No peeling
No flaking
Mechanical Finishes
Buffing is a mechanical finishing operation in which a buffing compound containing aluminum oxide is applied to the surface of an aluminum extrusion by rotating fabric wheels for the purpose of removing minor imperfections and developing a lustrous finish.
Sanding develops a desirable scratch finish using either flat or spiral sanders and is strictly done for cosmetic purposes. The amount of metal removed is dependent upon the grit finish used.
Otalum is one of the leading aluminum profile factories, of customed all aluminium profile products in Southeast-China. Want to know the details of black hard anodized coating, contact us.
