Wisconsin Batch Oven Cures Composites for Aircraft Manufacturing

03 January 2012

Wisconsin Oven designed and manufactured a gas fired batch oven to cure composite honeycomb material used in aircraft manufacturing.

According to Wisconsin, the composite curing oven has chamber dimensions of 120 wide x 280 long x 80 high and a maximum operating temperature of 500ºF. 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 hour and cool down to 150°F within 30 minutes.

They explain the composite curing oven is constructed with 6 thick tongue and groove panel assemblies and 20 gauge aluminised 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 utilises combination airflow to maximize heating rates and temperature uniformity.

Wisconsin says 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 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.
