Batch Oven Cures Composites for Aircraft Manufacturing
Wisconsin Oven designed and manufactured a gas fired batch oven to cure composite honeycomb material used in aircraft manufacturing. The curing oven has chamber dimensions of 12’0” wide x 28’0” long x 8’0” high and a maximum operating temperature of 500º F. The oven was designed with the capacity to heat the oven and 6,500 pound load of composite and steel fixtures from 70° to 400° F within one (1) hour and cool down to 150° F within 30 minutes.
The composite curing oven is constructed with 6” thick tongue and groove panel assemblies and 20 gauge aluminized steel interiors and ductwork. The heating system features a 3,000,000 BTU per hour high efficiency air heat burner including a motorized gas control valve, flame detector and flame relay with alarm horn. The recirculation system has a 50,000 CFM @ 40 HP blower, and utilizes combination airflow to maximize heating rates and temperature uniformity.
The industrial batch oven is specifically designed with composite curing features for precise temperature and pressure control. The exhaust features motorized dampers on both the fresh air inlet and the exhaust outlet for enhanced heating and cooling capabilities. Twenty-four (24) interior vacuum stubs were located throughout the oven. All of these composite curing features provide the customer with the ability to closely monitor part temperatures for a high quality cure.

The customer required a 35-point temperature uniformity of +/-5° F at 150° and 400° F. The oven has a UL certified NEMA 12 control enclosure with IEC style motor starters, push buttons, and pilot lights. The temperature for the oven is controlled by a Honeywell UDC 2500 programmable controller with autotune.
The customer also added Wisconsin Oven’s energy efficient E-PackTM oven upgrade to the composite curing oven, which includes thicker wall panels, higher efficient motors, a door limit switch, and a few other energy saving items that will reduce their operating costs.
