An electrically heated spiral conveyor oven with cool down will be used to cure adhesive applied to exterior automotive mirrors.
Built by Wisconsin Oven Corp., East Troy, Wis., the oven has a maximum operating temperature of 392°F (200°C). When preheated, it has sufficient capability to heat 840 lb of glass and 1,200 lb of aluminum trays per hour at a normal operating temperature of 320°F (160°C), according to the manufacturer. The automotive components supplier required temperature uniformity of ±9°F at 302°F (±5°C at 150°C) for a minimum of 45 minutes.
The equipment was designed to specific dimensions to ensure all mirrors were cured evenly. In addition, a spiral conveyor design was implemented to both save on floor space and maximize the number of mirrors processed per cycle.
