The DTI-971 indexing conveyor oven is a thermoforming system that preheats interior components used in the automotive industry. This industrial oven was provided with a pick and place system to load the products onto the oven conveyors. One product is conveyed through the upper level of the oven and heated by forced air convection.

Another product is conveyed through the lower level of the oven and heated by infrared panels. The infrared panels are arranged in individual zones of control to allow for variations of heating across the entire surface of the product. After the preheating process is complete, both products exit the two levels of the oven simultaneously. They are then matched together to form a preheated vehicle set ready to be press formed as a single unit. The cycle times can be varied and can be as short as 30 seconds.




  • Automated processing from precut blanks of material to preheated vehicle set ready to press
  • Part to part cycle times as short as 30 seconds in this application
  • System includes capability to meet variable color and quantity requirements of the manufacturer
  • The system also includes the capability to produce product for both coupe and sedan models in three different colors in any sequence simultaneously


  • Upper convection oven section is heated by gas and the lower infra red section is electrically heated
  • PLC controlled with operator touch screen (HMI)
  • All motion functions controlled by servo for accuracy and speed

Davron exists to be the industry leader in non-standard products engineered to meet the customer's need and unique process.
