DTI-784 Pre Heating Rack 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-784 industrial oven is a thermoforming solution that preheats cotton and polyethylene backing material used in the manufacturing of interior components for the automotive industry. The process requires that the blank be heated from both sides. This industrial oven includes a product rack that operates on a series of tracks and rollers. The blank of material is manually loaded onto the rack. A signal tells the pneumatically operated vertical door to open, and the rack is indexed into the oven.
Once the rack is in the oven and the door closes, the cycle timer begins. The material blank remains in the oven chamber for approximately 55 seconds, and heated air is impinged to both sides of the product. At the end of the cycle, the door opens and the rack exits the heated chamber. The material blank is then unloaded. The rack extends out of the oven 6′-4″ for the loading and unloading process. The entire oven is mounted on v-groove caster, providing the required mobility during press tooling changes.
