Aluma-Flex Band Heaters

The element utilized in the Aluma-Flex Band Heater is the highly efficient, rugged, long lasting tubular heater pressed in a grooved aluminum extrusion. The combination of the tubular heater in exact contact with the excellent thermal conducting aluminum extrusion create a quick responding band heater with uniform sheath temperatures for precise process heating. With the termination a significant distance from the part being heated and no other place for contaminants to enter, the Aluma-Flex is virtually indestructible. A low expansion alloy strap with mounting hardware allows the assembly to be tightly drawn to the part to be heated. With sheath temperatures to 650° F attainable, the Aluma-Flex Band Heater is ideal for use on barrels of plastic extruders, injection molding machines, dies and die heads of extruders and blow molding equipment, or, within temperature limitations, any cylindrical surface.
