DTI-898 Roll Processing Preheat System
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-898 roll processing preheat system is a thermoforming oven used in manufacturing automotive interior floor carpeting. The system pulls product to length, cuts, and preheats both the carpet product and padding simultaneously. At the completion of the cutting process, the materials are introduced to the oven for preheating. The pad is conveyed through the upper level of the oven and heated by forced air convection.
Carpet 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, allowing for variations of heating across the entire surface of the carpet. After the preheating process is complete, both the pad and carpet 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 total cycle time from part to part can be as short as 45 seconds in this application.
