Wisconsin Oven, East Troy, Wis., has shipped a natural gas direct-fired three-zone conveyor oven with cool down, to a leading supplier of flooring products for curing adhesives at a rate of 350 parts per hour.
The curing conveyor oven was designed with three heating zones and one cooling zone. Each zone includes a personnel access door for maintenance and service. The curing oven has a maximum temperature rating of 600°F and total work chamber dimensions of 5x45x1 ft.
Guaranteed temperature uniformity of ±10 degrees at 400°F was verified through a temperature profile test using measurements from 30 inches from each opening, in a stabilized oven. An infrared pyrometer monitors the part temperature at the exit of both the final heating and the cooling zone. If the product temperature exceed its setting, an alarm will sound. The conveyor oven is rated for Class A use as defined by NFPA 86, with a solvent rating of 0.14 gallons per hour.
“We strive to design our equipment to provide the best quality part results for our customers,” says Gene Vetter, Application Engineer. “In this case, three heating zones followed by a cool down zone resulted in the highest quality cure for their product, while the conveyor system maximized their production rate.”
This conveyor oven was fully factory tested and adjusted prior to shipment to and from the facility. All safety interlocks were checked for proper operation, and the equipment was operated at the normal and maximum operating temperatures. A 150-point quality assurance check list was completed to ensure the equipment met all Wisconsin Oven quality standards.
