Wisconsin Oven Ships Curing Batch Oven to the Aerospace Industry

Nov 17, 2022

Wisconsin Oven Corporation announced the shipment of one (1) Electrically Heated Batch Oven to a leading manufacturer in the aerospace industry. The batch oven will be used for curing composite materials and is designed to meet the requirements of AMS 2750F, Class 2 furnaces and Instrumentation Type A.

The batch oven has a maximum operating temperature of 300°F, work chamber dimensions of 12’ wide x 40’ long x 10’ 6” high, and work zone dimensions of 6’ wide x 35’ long x 8’ 6” high. OSHA-compliant railings were included to provide roof access around the entire roof of the oven with two (2) OSHA-compliant ladders, self-closing gates, and safety cages.

This composite curing oven has sufficient capacity to heat and cool 20,000 pounds of steel and composite material. The airflow arrangement maximizes heating rates and temperature uniformity of the product by supplying air to the work chamber through ductwork located along the length and on each side of the work chamber, near the bottom of the chamber, to ensure that the air passes past the product on the way back to the heater house. Temperature uniformity of ±10°F at set points 120° and 260° was documented with a forty-five (45) point profile test in an empty oven chamber under static operating conditions.

 “The recirculation system for this oven is designed with a total of 148,800 CFM to maximize heating rates throughout the chamber and product. An extensive temperature uniformity survey was performed prior to shipment to ensure the oven met the requirements of AMS 2750F, Class 2 furnaces and Instrumentation Type A.” – Tom Trueman, Senior Application Engineer

Unique features of this curing oven include:

  • Temperature uniformity of ±10°F at 120° and 260°
  • Interior lighting to illuminate the interior
  • Four (4) 37,200 CFM recirculation blowers
  • Allen-Bradley ControlLogix PLC for system control
  • One vertical lift, pneumatically operated door
  • Four (4) 12-position Type J thermocouple jack panels

This composite curing oven was fully factory-tested and adjusted prior to shipment from our facility. All safety interlocks were checked for proper operation and the equipment was operated at the normal and maximum operating temperatures. An extensive quality assurance checklist was completed to ensure the equipment met all Wisconsin Oven quality standards.
