Wisconsin Oven Corp., East Troy, Wis., shipped a four-zone conveyor oven to a manufacturer in the oil and gas industry. The electrically heated oven has the capability to heat 25 parts per hour with a heating time of 48 minutes and a cooling time of 12 minutes. Each chamber in this four-zone oven has a maximum temperature rating of 752°F (400°C).
The oven has a guaranteed temperature uniformity of ±10.8°F at 590°F (±6°C at 310°C) for a minimum of 6 minutes per heating chamber and with a belt speed of 2” per minute. A 1,500 CFM propeller fan cools the parts utilizing top-down airflow, where cooling air will be discharged into the shop from below the unit.
According to Wisconsin Oven, the oven was designed with four zones in order to melt a high-temperature polymer into a U-shape ring that houses electronic components.
