Understanding the Basics of Barrel Tumbling Detailed

Although the abrasive process creates a smooth surface, the surface will not be smooth enough to take a polish and further abrasive operations are necessary. Polishing (Dry Tumbling) This is the most critical operation in the finishing of plastic parts. Should the surface of the plastic parts be too rough, a
