DTI-954 Horizontal Heat Treat System

This multiple zone conveyor type 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.
