DTI-1139 Double Tier 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-1139 industrial oven is a a thermoforming solution that preheats 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 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.
