Aluminium extrusion surfaces often contain die lines, oxide film, handling marks and uneven texture that remain visible after anodizing or coating. Manual polishing is labour-intensive and can result in inconsistent gloss, excessive heat generation and profile-to-profile variation.
Valgro’s automatic aluminium profile polishing machine uses rotating polishing wheels with suitable polishing compound to create a uniform high-gloss surface. The controlled linear feeding system maintains consistent contact between the profile and polishing wheel, improving productivity and finish repeatability.
The machine can be configured according to the profile shape, size, production volume and required gloss level. It is an ideal solution for aluminium extruders, architectural profile manufacturers and decorative component producers serving domestic and export markets.
