DTI-954 Indexing 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-954 multiple zone indexing conveyor oven heat treats automotive coil springs used for suspension systems. The coiled springs are placed in custom trays included with the conveyor oven system, and are conveyed through the oven for tempering. The tray system processes six parts per row and the conveyor oven system indexes based on timed increments through the length of the oven. Multiple heat zones are included to allow temperature variations used to create temperature profiles. The process requirement dictates that parts are heated at a controlled rate up to the maximum temperature. Temperature is reduced at a controlled rate prior to exit from the system.
