This customer molds a variety of glass filled plastic and wood composite items. The process creates significant flash on the edges that needs to be removed. The current process involves hand sanding that is time consuming, labor intensive and does not result in an even finish across the entire surface area of the part.
Since these parts cannot get wet (due to swelling and potential damage) the parts were vibratory tumbled with a fast cutting (KSF) Ceramic Angle Cut Cylinder Media with no water and no compound. The cycle time required to get a smooth, slightly rounded edge with a uniform surface finish across the entire part was only 30 minutes.
