Davron Continuous Conveyor Oven Cuts Labor Cost and Energy Comsumption


Davron Technologies, Inc. designed and manufactured the DTI-775, a gas-fired continuous conveyor oven, to cure disc brake pads for an automotive Tier 1 supplier. Previously, the customer cured the product using a batch process in which parts were staged, loaded onto carts, and transported to batch ovens. The DTI-775 continuous conveyor oven eliminated the labor cost and work-in-process associated with staging, loading and unloading, and moving the parts in and out of the batch ovens. By loading parts into the DTI-775 immediately after the press cycle, the customer can retain the heat absorbed by the parts when they are pressed, reducing the energy required to cure the product.

Featuring one natural gas full-modulating burner, the custom oven can be programmed to operate between 300º and 662ºF. The oven includes two circulation fans delivering heated air to the product in a vertical top-down pattern. For the conveying system, the oven utilizes a custom tray arrangement that accommodates eight parts per tray. The parts stand on edge, reducing the space required for each part, as well as the oven footprint. The conveying system moves product through the curing chamber and the cooling chamber. The cooling chamber utilizes ambient air to cool the parts to approximately 130ºF immediately after the curing cycle is complete. The oven is designed to process 384 parts per hour.

The useable dimensions of the oven, including the cooling chamber, are 6’7” wide x 0’6” high x 10’8” long. The interior of the oven is made out of 16-gauge aluminized steel backed by six inches of eight-pound density mineral wool insulation. The exterior is constructed of 16-gauge carbon steel backed by a structural steel frame and finished with high temperature paint. The oven includes two doors that provide access to the heated chamber for maintenance.

Davron designed the DTI-775 continuous conveyor oven based on three criteria provided by the customer: the production rate per hour, the temperature range, and the time required for curing. Once the continuous conveyor oven was manufactured, Davron did acceptance testing and training with the customer at Davron headquarters in Chattanooga, Tenn., prior to shipment.
