Wisconsin Oven Ships Custom Spiral Conveyor Oven
Wisconsin Oven Corporation announced the shipment of a custom electrically heated spiral conveyor oven with cool down. The conveyor oven will be used to cure adhesive applied to exterior automotive mirrors. The conveyor needed to be designed to the customer’s specific dimensions to ensure all mirrors were cured evenly. To save on floor space and maximize the number of mirrors processed per cycle an innovative spiral conveyor design was utilized in both the heat up and cool down chambers.
The maximum operating temperature of the spiral conveyor oven is 200°C. The conveyor oven, when preheated, has sufficient capability to heat 840 pounds of glass and 1,200 pounds of aluminum trays per hour at a normal operating temperature of 160°C. The oven chamber and cool down chamber each have dimensions of 6’4” W x 6’4” L x 9’2” H and utilize four (4) 5,000 CFM blowers for a total of 20,000 CFM. The customer required temperature uniformity of ±5°C at 150°C for a minimum of 45 minutes.
“At Wisconsin Oven we are continually working on innovative design solutions for our customers. For this project we needed to meet our customer’s production requirements within the facility space available which required a unique spiral conveyor design to minimize the footprint of the oven and at the same time meet their targeted production rate.” -Tom Trueman, Senior Application Engineer
Unique features of the conveyor oven include:
- Spiral belt conveyor design
- Filtered ambient air intake for cool down chamber
- Parts are transferred to the production line by the exit conveyor
- PLC controls with Ethernet communications that notify the operator of various equipment alarms
- Over temperature protection
- Six (6) monitoring thermocouples mounted in the oven heating chamber
