DTI-938 Powder Coat Cure 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-938 specialized oven system cures powder paint on metal panel assemblies. This system utilizes both infrared and convection heating to complete the cure process. The conveyor design speed is 18′ (5486mm) per minute, providing 40 seconds of infrared heat, followed by 10 minutes of convection heating, and completed with 21 seconds of cooling.
The infrared section provides heat by using a series of gas fired infrared burners located on each side of the product. This section is used to heat the powder paint very quickly to gel the paint to the parts to prevent the convection section from blowing the powder paint off the parts. The infrared is followed by 10 minutes of forced air convection heat to finish the cure process.
Features
Custom oven construction features
The air circulation within the convection chamber is vertical up, and air is circulated through a burner box located on top of the system. The final section is a cooling section designed to reduce the part temperature prior to exit. This section also serves as a vestibule to limit the amount of heat escaping to the plant. The system design provides the ability to cure 12,000 pounds of product per hour at design speed.
