Deflashing Fiberglass

Heavy flashing on edges

This molded fiberglass part has heavy flashing on the edges that needs to be removed more efficiently than a hand sanding or scraping operation. In addition, a dry process is preferred (in this situation) so the customer does not need to take the extra step of drying the part prior to further processing.

No flashing after vibratory tumbling

A dry tumbling process using Hardwood Peg Media and Dry Abrasive Cream successfully removed the flashing and produced a smooth, rounded edge. In this type of process, the compound is 'coated' to the Pegs and tumbles against the part to abrade away the flashing. If necessary (but not required in this situation), different dry tumbling compounds can be used to polish the part or even produce a high gloss finish.
