Delta Air Lines ordered a 500°F (260°C) vacuum-assisted composite curing (VACC) oven for manufacturing parts for its airplane cabins. The VACC process involves drawing a vacuum on composite layups in vacuum bags while they are cured in an oven. Lewco Inc., Sandusky, Ohio, supplied the composite curing oven.
Composite curing ovens manufactured by Lewco include a vacuum pump, thermocouple jacks and vacuum ports. The oven purchased by Delta has 22 vacuum ports in the workspace that are connected to control valves on the exterior of the oven. Thermocouples are attached to the layups to monitor and record the temperature of the parts being manufactured.
