Valgro Aluminium sheet polishing machine is used to have brush finish, hairline, and matt finish before anodizing. Abrasive Brushes clean the surface of the aluminum and eliminate scratches, marks, foreign particles, and other residue. The etching duration of satin-brushed aluminum prior to anodizing is much less than the un-brushed counterparts resulting in less chemical consumption in etching and wastewater treatment, therefore a considerable decrease in production costs.
The obtained finish is of fine mechanical satin type, with excellent appearance like Scotch-Brite. Different type of abrasive grit brush offers smooth and uniform brush effect with dry process.

The highest possible degree of surface finish is usually desirable, for two quite distinct reasons.
