Aluminum products surface finishing
To understand aluminum products surface finishing, we should understand which manufacturing process to manufacture aluminum parts. It is as below:
- Aluminum milling, turning, CNC machining, drilling and girding etc. Now we call it aluminum machining,
- Aluminum extrusion,
- Aluminum die casting,
Aluminum products anodizing finishing
To place aluminium products or aluminium alloy products into an electrolyte solution with power handling , using electrolysis alumina film formed on the surface of the process called anodic oxidation or anodizing.Anodized aluminum surface can be generated by a few microns—hundreds of microns in oxide films.
With this process, it is possible to make various anodizing aluminum color with scratch resistance.
What kind of aluminum manufacturing products is good for anodizing?
- Sheet fabrication,
Die casting aluminum products is not good for anodizing, it will have lots of quality issue.
Brush finishing for aluminum products
It is have sandpaper to frict aluminum products surface, the sandpaper is moving in uniform controled by machine to frict aluminum product. Generally the brushed surface should be flat, than it is easier to controlled by operator.
All of the aluminum manufacturing products is okay to have the brushing finishing, but the brushing surface should be flat. For the die casting aluminum products, it should be painted by transparent oil after brushing to prevent to be oxidized.
Sand blast for aluminum products
Sand blast process is to use compression air to have abrasive spray on aluminum products to have fine texture on the aluminum products surface finishing.
