Bonnell Aluminum introduces acid etch anodizing

Post Time:Nov 12,2013Classify:Industry NewsView:77

Bonnell Aluminum, Newnan, Ga., will invest $1.1 million in the conversion of all of its existing anodizing product lines to the acid etch process, according to a Jan. 14 company release. Acid etched anodic coatings will be available exclusively starting April 1, 2009.

Available in Class I and II, clear, bronze, and black finish, acid etched anodic coating has superior characteristics for finish consistency than typical anodizing, resulting in a more uniform finished product. “Manufacturers and installers of curtain wall components, storefronts, automatic entry doors, walkway covers, and other anodized building and construction applications will immediately recognize the benefits of this superior finish,” said Ira Endres, director of sales and marketing, in the release. “While meeting and exceeding all AAMA 611 specifications for anodizing, the acid etch anodic process is far better in hiding extrusion surface imperfections than caustic etch anodizing. It virtually eliminates the appearance of visual streaks and die lines while providing a superior uniform matte finish.” More environmentally friendly and greener than a conventional caustic etch process, the acid etch process requires less etching time, which significantly reduces the amount of waste sludge disposal by as much as 90 percent, according to the release. In addition, the process enables the use of a higher percent of recycled content in extrusion billet while still maintaining high uniformity of finish.

This capital investment project is of second importance in recent months. In the third quarter of 2008, Bonnell Aluminum announced a $25 million expansion project for its Carthage, Tennessee facility, with the addition of a 5,500 ton hydraulic extrusion press, handling systems and ancillary equipment, specifically engineered to extrude products requiring critical surfaces for high profile exposed architectural applications. The new press will be capable of producing aluminum extruded profiles up to 16 inches of width, according to the release.
