NASCO, a manufacturer of suspension coil springs and trunk-lid torsion bars for the global automotive market in Bowling Green, KY, was using electrocoat painting to finish its products on one of its production lines. As new orders were increasingly specifying powder coatings, the company needed to add powder coating to a line that was originally built only for E-coat. That would have required two separate ovens taking up space on the production floor. But space was limited at NASCO, and company officials feared that having both processes and adding two new curing ovens would negatively impact other parts of the production process. In cooperation with local authorities NASCO was put in touch with Fostoria Industries Inc., a company, that had been working on new technology that involved putting an IR boost inside a convention oven. Within two months of signing the contract, the system was built. It employs quartz tubes and insulated board as reflectors. Quartz tubes were used because they are basically impervious to the high oven temperatures. The surface of the board reaches a temperature that the board becomes a secondary IR emitter and this temperature is also high enough that it is basically self-cleaning. The new combination oven was installed on the third of NASCOs four finishing lines. Finally, it increased production and reduced energy requirements without hindering the production process elsewhere in the plant.
