Industrial Finishing: Coatings Manufacturing & Application

From Thermal Innovations Corporation
 

 

A new combination infrared/convection oven is bringing a number of advantages in the curing of an assortment of powder-coated telephone communications equipment for a California manufacturer. Hendry Telephone Products, located in Goleta, just west of Santa Barbara, makes racks, frames, fuse panel boxes and various other products. The steel and aluminum parts vary in size from small, thin-gauge components to bulky thick-gauge structures weighing over 200 lb.

The 72-ft oven accommodates components up to 3 ft wide and 4 ft high. It allows the curing of parts in as little as 5 min. The thick-gauge large parts are cured in as little as 14 min.

The initial eight-zone electric infrared section quickly ramps up the temperature of surfaces receiving the line-of-sight radiant heat. The three-zone gas convection section then raises the temperature of surfaces hidden from the radiant heat.
