DTI-1244 Double Tier Indexing Pre Heating Conveyor Oven
Customer directive
Our customer wanted to create an indexing single part flow inert atmosphere production furnace system to match, and seamlessly integrate into, the customer’s entire existing manufacturing process at a production rate of 45 seconds part to part. The customer’s then existing process included inefficient batch furnace staging of parts at this point in the process.
Description
The DTI-1244 indexing conveyor oven pre heats interior components used in the automotive industry. Product can be loaded on the oven conveying system with an automated pick-and-place system or manually by operators. One product is conveyed through the upper level of the system and heated by contact heating.
Another product is conveyed through the lower level of the oven and heated by forced air convection. 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 time can be varied depending on product and production rate.
The conveying systems for both the upper and lower levels operate in an indexing manner. As a preheated set indexes out of the heated areas new blanks are indexed into the heated areas to be preheated.
