The DTI-1031 muffle annealing furnace anneals glass components used in the automotive industry. In this particular project, DTI did not provide the custom conveying system. The customer provided all of the custom tooling and conveying chains to move the product through the oven. The process includes product being loaded into custom tooling via a pick and place system. The product travels through the furnace at a rate of approximately 1″ (25mm) per second throughout the entire system. After the product travels through the heated portion of the furnace for the first 12′-0″ (3658mm), it then enters a cool down portion for the final 6′-0″ (1829mm). Bulbs are removed from the custom tooling via a pick and place system.

Davron exists to be the industry leader in non-standard products engineered to meet the customer's need and unique process.
