DTI-1200 Overhead Monorail 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-1200 Overhead Monorail Conveyor Oven System is used to heat an instrument panel used in the automotive industry. This particular instrument panel is made of a polypropylene material. The overhead monorail conveyor oven described here is the oven located on the left in the associated photographs.
The intent of this overhead monorail conveyor oven is to heat the surface of the instrument panel to the desired temperature to prove the adhesion of an adhesive component applied to the raw product before a cover is added. The oven utilizes an overhead monorail conveyor system with custom product hooks for transporting product through the oven chamber.
The operation of this oven is continuous and allows the product to make 3 passes in the heated chamber. This arrangement provides the desired dwell time within the heated chamber. The conveyor speed is adjustable controlled by variable frequency drive. The heated chamber consists of 2 individual zones of temperature control to provide adjustability to the heating profile. Each zone is 50% of the heated chamber length. Heat to each zone is provided by electric heaters. The airflow within the heated chamber is a horizontal cross flow pattern. Heated air is supplied to the product from one of the vertical side walls in the heated chamber.
