DTI-1240 Contact 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
This contact heater system is used to preheat carpet products used in the automotive industry to make interior components. The system features 2 heated platens. The upper platen is heated by electric tubular heaters that are inserted into drilled holes in the thickness of the platen. This platen is divided into 8 zones of control in order to provide optimal heating across the entire surface. The lower platen utilizes hot water (glycol) for heating. The lower platen also includes drilled holes that accommodate fluid ports over the entire area of the platen. The upper platen has an operating temperature range of 200°F – 500⁰F and the lower platen operates at temperatures up to 210⁰F.
Product is manually loaded onto the lower platen. The upper platen travels vertically to the product during the preheating cycle. The pressing force is applied by the upper platen vertical travel. The opening/closing force required is provided by a hydraulic system. The location of the lower platen is fixed and the upper platen travels to adjustable hard stops to control platen spacing for material thickness. After the preheating cycle is complete the product is manually unloaded from the lower platen. Both the upper and lower platens are provided with teflon coated covers to prevent the product from sticking.
