Vibratory Finishing

The comprehensive metal finishing services available from Master Finish Company includes vibratory finishing. Vibratory finishing is a process in which smaller parts or components are placed in a tub or bin with burnishing media, which can include ceramics, plastics, granite, steel balls, or organic media such as ground walnut shells or corn cobs. An asymmetrically weighted motor then creates vibration to achieve the desired results as components and media collide.

The vibratory finishing process is used for deburring and polishing to remove heat treat scale and to radius sharp corners and edges of metal components. It removes parting line flash and provides a smooth finish to enhance appearance of subsequent decorative plating.

Specific objectives can be achieved by varying the severity and pace of the vibration, and the nature and amount of the media used. Vibratory finishing is often used to create improved surface quality prior to plating.
