Wisconsin Oven Ships Sand Core Drying Ovens to the Foundry Industry

Jul 26, 2017

Wisconsin Oven Corporation shipped two (2) Natural Gas Fired Enhanced Duty Walk-In Series Ovens to the foundry industry. The batch ovens will be used for drying sand cores used in the casting process of a variety of parts. The sand core dryers have the capability to dry water and resin from 6,000 pounds of sand cores and a 600-pound steal load car from 70°F to 450°F within 2 hours.

Each of the work chamber dimensions of these sand core dryers is 10” W x 8” H x 20” L with a maximum temperature rating of 500°F. Guaranteed temperature uniformity of ±10°F at 500°F was documented with a nine (9) point temperature survey. The oven bodies were constructed with tongue and groove panel assemblies featuring Wisconsin Oven’s patented high efficiency panel seams that provide 25% better insulating efficiency.

“These sand core dryers were designed to maximize efficiency and decrease drying time of the cores. The customer is able to pour and dry more cores in less time than before resulting in an increase to their production.- David Burke, Sales Representative, Torrid Enterprises
