Curing The IR-convection curing system: De- signing effective curing processes to meet today's production needs. Sher- rill Stoenner. November 2006, p. 16. Manufacturers of the twenty-first century are constantly seeing their processes chang- ing to keep up with the demand for in- creased productivity while reducing costs. Today's manufacturer is being asked to produce more products with less process in- ventory and a smaller workforce, and to a higher quality than ever before. To meet these demands, the finishing process also has to change. Manufacturers can't com- pete in today's world with the same finish- ing process they've used for the past several decades. This article discusses the problems that can occur with old curing systems and how they can drain a finishing line of en- ergy and efficiency, which ultimately leads to decreased profits. The article then dis- cusses how ovens that combine infrared with convection technology can boost effi- ciency and lead to increased profits. Essentials to understanding infrared processing. Allan N. McKellar. No- vember 2007, p. 18. Infrared processing and convection pro- cessing have differences. This article dis- cusses those differences and explains why no simple math can be applied to calcu- late the energy density requirement of the IR process. The article stresses the impor- tance of choosing a supplier who can pro- vide access to a quality test facility that en- compasses the various IR technologies (long-, medium-, and short-wavelengths) to find the most suitable process for your curing requirements. To get the color right, a pigment man- ufacturer expands its curing capabili- ties. (Benda-Lutz, Independence, Ky.) November 2008, p. 20. If you've ever had to repaint a room and you just wanted to keep it simple and paint it white, this seemingly basic coat- ing solution can quickly become alarm- ingly complex and nuanced. Do you want glossy, semi-gloss, flat, or satin? And the endless color cards and rows of color chips claiming to be white, range from a yel- lowy ivory to a pristine marshmallow hue and everything in between depending on the pigment cocktail. After shaking the can and putting the first coat on the wall, does the color still look like the chip you based your selection on? When a powder that is white in the lab comes out yellow- ish on a finishing line, an aluminum pig- ment manufacturer embarks on a prob- lem-solving odyssey that reveals a funda- mental difference between cure ovens. Oven primer: An introduction to in- dustrial process ovens. J.W. Guanci, III. November 2010, p. 11. Virtually every manufactured product re- quires the introduction of heat at some point during the production process. Pur- chasing the proper piece of thermal pro- cessing equipment is rarely an easy or a casual consideration. Reputable oven manufacturers share those exact senti- ments, in that they will consider a custom- er's application, production needs, and concerns seriously. It's also understood that multiple issues become intertwined to create a series of details which must be re- solved before trust is gained and equip- ment is purchased. This article serves only as a general guide to heat processing equipment and the issues that must be considered to select the proper oven, as well as the appropriate options and fea- tures. Of course, for an application-spe- cific diagnosis, consultation with a mem- ber of your oven manufacturer's sales team is always recommended. Planning and courage build new pow- der coating business. (Aegis Industrial Finishing, Vancouver, B.C.) Novem- ber 2011 digital issue, p. 18. Facing stiff competition from China that was making the powder coating of high-volume small parts increasingly com- petitive, Dave McKinnon decided to de- part the business that his father-in-law had established in 1948 in Vancouver, British Columbia, Canada. Despite the difficult decision to leave the business in which Dave had worked for more than 20 years, Dave and his son Chris decided to launch a new business that would handle a mix of larger parts in a smaller volume. Labware-maker boosts production with a more efficient compact oven. (Bel-Art Products, Pocomoke City, Md.) No- vember 2012 digital issue, p, 15. When Kurt Landsberger and wife Anny launched Bel-Art Products, it was a small shop making household items, such as aprons and tablecloths for post-World War II consumers in 1946. Soon realiz- ing the value in the chemical resistance of the plastic material used to make these items, the Landsbergers started marketing their products for laboratories and medi- cal-supply companies, becoming pioneers in the use of plastic lab equipment. Nick's Niche: Part cooling techniques: Why it's important to "Cool it!" Nick Liberto. April 2014, p. 27. It seems that our concerns about properly curing the powder coating on a part overshadows the cooling of the part, even though it has equal importance in a well-designed powder coating process. So I thought I would provide you with the information necessary to give you a per- spective about powder coating system de- sign that you may not have properly con- sidered before. PC
