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-1182 vertical drying oven is used to heat a product web and remove moisture (solvents) from the product by heated evaporation. The system includes 2 LEL monitors with multiple alarm functions and display screen. The system is designed to accommodate a web up to 40″ wide. The oven chamber is designed to allow the product to make 3 vertical passes (up and down). The oven includes 3 applicator tanks located under the heated chamber. These tanks contain the solvents and the web passes through the tanks to apply the solvents to the web. Each applicator tank includes a pneumatic system to raise the tank to the “in use” position or lower the tank when not in use or being cleaned. A wiper bar is included above each tank (prior to the oven chamber) to allow the thickness of the coating to be adjusted. The oven includes a power edge trim rotary knife that trims both edges of the web as it exits the oven chamber. A system is provided prior to the take up roll that applies a small amount of powder to the web. This prevents the layers of the web from sticking together after is rolled up on the take up roll.
