Abstract
A process and apparatus for dissipating static electrical charge that may build up on the small plastic parts, the tumbling medium or the tumbling chamber itself during an abrasive tumbling process and cause the parts to be repelled out of the abrasive medium. A flow of ionized gas is distributed about the tumbling chamber, discharges the parts and provides a mechanical action to return the parts to the abrasive medium. This flow of ionized gas dissipates the static charge.
