Surface Treatment

Coating Systems Inc.'s surface treatment processes extend the one-stop shop's capabilities to offer value to many customers. Proper surface preparation improves the process quality, as well as the parts' metallurgical properties. We offer tumble finishing and air blasting services to improve your product's quality.

Tumble Finishing

Air Blasting

Tumble finishing, also known as tumbling or rumbling, is a technique for smoothing and polishing a rough surface on relatively small parts. Metal tumbling is used to burnish, deburr, clean, radius, de-flash, descale, remove rust, polish, brighten, surface harden, prepare parts for further finishing, and break off die cast runners. The process is simple: a horizontal barrel is filled with the parts which is then rotated. Variations of this process usually include media, water, or other lubricants. As the barrel is rotates, the material rises until gravity causes the uppermost layer to landslide down to the other side. The barrel may also have vanes, typically made of rubber, that run along the inside of the barrel. As the barrel turns, the vanes catch and lift the parts, then slide down or fall to finish the tumbling action.

Our Pro Finish Surface-Treatment System allows industrial air blasting, also known as bead blasting and sand blasting, on-site for numerous applications. For surface finishing, it can add a matte or satin effect, remove glare, eliminate imperfections and blend marks. For cleaning, it can remove chemical impurities, paint, coatings, sealants, adhesives, carbon deposits, scale, excess brazing, casting material, flashing burrs, rust, or oxidation. For surface preparation, it can add fatigue resistance, improve wear properties, profile surfaces, create porosity, create friction, improve lubrication, or etch for bonding and adhesion.
