Read how the Surface Matrix Sealing System (TM) from IMPCO can lower parts rejection rates via a technique known as "filling porosity." 07 June 2010
Ron Joseph, Metal Finishing's organic coatings editor, delves into the tricky situations regarding pretreatment, painting of steel, and phosphate, among other related issues. 29 September 2009
Air blasting contributes to more productive cleaning and pretreatment by making short work of otherwise time-consuming and labor-intensive tasks. For many metal finishers, particularly shops that rebuild parts, prep work often represents more than half the battle. Success depends on maximizing surface receptivity to whatever procedure follows and, in many cases, maintaining part dimensions during cleaning or profiling. Because of its versatility and dexterity, air blasting excels in many challenging pretreatment and cleaning jobs. 14 September 2009
Zirconization, an alternative, phosphate-free, eco-friendly coating pretreatment procedure, addresses energy and chemical consumption while improving product quality. 21 January 2009
Alan Ensign, vice president and general manager of Wyandotte, Mich.–based Cadon Plating & Coatings, is no stranger to trying times. When the company abandoned the commodity-driven rack plating business years ago, revenues took a 30% hit. Then in in 1994, government regs forced its exodus from the cadmium plating market and, much later, the olive-drab business. As a result of that move, 25% of sales vaporized—just like that. If those setbacks weren’t enough, the company lost once-steady business when the U-bolt suppliers for several major auto suppliers installed their own paint lines, essentially cutting out Cadon completely. 15 May 2007
In industries such as office furniture, home appliance, automobile, or electrical components construction, metal pretreatment is currently used before paint application. Its purposes are the adhesion of the future paint coat and anticorrosion properties. The state of the art consists of applying phosphating salts over the surface during a complete process. 08 December 2005
