process for mechanically polishing aluminium sheets

Sanding process

Sanding is another technique used to produce the desired texture on aluminium sheet products, usually in the form of a large belt sander. The surface finish produced by sanding can be in the form of tiny parallel lines etched in the same direction on the surface of the product, or tiny grooves that create a feathery texture and reduce the reflective quality of the aluminium. Another popular effect is the cross-line pattern. This finish is commonly used on bathroom hardware, picture frames and other aluminium extrusions.

Shot blasting process

Another process for mechanically polishing aluminium sheets is shot blasting, which produces a granular finish that helps to hide excessive surface imperfections.

Tumbling process

Tumbling is a versatile method of mechanically polishing aluminium sheets, helping to deburr, clean and polish.
