Edge Finishing

Diamond Polishing

Heavy duty polishing machines equipped with progressively finer grits of diamond impregnated segments or disks are used to gradually grind down surfaces to the desired degree of shine.

Flame Polishing

Flame polishing uses a hot flame to flow a plastic surface. Operator skill is critical with this method. When done properly, flame plastic polishing produces the clearest finish, especially when polishing acrylic. Flat external surfaces are the most applicable configuration for this method.

Wet Sanding and Scraping

Wet sanding will yield a smooth, matt-finish edge and is suitable for use prior to flame polishing. Dry sanding is not recommended, as it will lead to a highly stressed and melted edge.

Buffing

Buffing the edges of acrylic sheet will produce a high lustre finish. It is recommended that the edge be scraped, then wet sanded prior to buffing. A stationary buffing wheel or portable polishing head can be used. Loose stitched, bleached muslin wheels, used in combination with a medium to fine buffing compound will provide a high luster edge in a short time.
