Davron Technologies, Inc. designed and manufactured the DTI-971, a natural gas and electrically heated indexing conveyor oven designed to preheat interior components for a Tier 1 automotive supplier. Prior to commissioning the DTI-971, Davron’s customer preheated the products in two separate ovens. The DTI-971 indexing conveyor oven enables the user to preheat the products simultaneously in the same oven, thereby reducing the labor, energy, and work-in-process needed for production.

The DTI-971 features two heated chambers and conveying systems. The upper chamber is heated by a natural gas burner and preheats product via forced air convection. The lower chamber utilizes infrared panels arranged in individual zones of control to allow for variation of heating across the entire surface of the product. The upper (convection) chamber can operate between 300ᴼ and 500ᴼF, while the lower (infrared) chamber can operate between 200ᴼ and 800ᴼF.

Product is loaded onto the oven conveying systems with a custom automated pick-and-place system designed by Davron. After product is loaded onto the upper and lower conveying systems, they are indexed into the heated chambers. The product is indexed one position at a time and moves through the heated chamber according to predetermined time and distance settings until the preheating cycle is complete. Once preheated, the products exit the oven’s heated chambers simultaneously. They are then matched together to form a preheated vehicle set ready to be press formed into a single unit. The DTI-971 features PLC control and all motion functions are controlled by servo for accuracy and speed.

The usable dimensions of both heated chambers are 13’2” wide x 13’6” 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 lower chamber features a removable drawer that houses the infrared panels. This drawer slides out of the oven to allow access to the IR panels for maintenance. The upper chamber includes six access doors on each side to provide access for maintenance and ensure compliance with NFPA requirements.

Davron designed the DTI-971 indexing conveyor oven and complimentary pick-and-place system based on two criteria provided by the customer: the production rate per hour and the temperature required to preheat. Once the indexing conveyor oven was manufactured, Davron did acceptance testing and training with the customer at Davron headquarters in Chattanooga, Tenn., prior to shipment. Davron then went on site to install the oven at the customer’s facility.
