General Description and Construction
The Marathon Starflex band heater is an extruded aluminum segmented band employing rugged refractory insulated tubular heating elements. The low expansion clamping band provides snug barrel fit and and assures excellent heat transfer through the entire operating temperature range up to maximum heater temperatures of 600°F. This band heater enjoys wide acceptance because of extremely long and reliable life characteristics. Operators of plastic extruders and injection molders experience minimum down-time with the Starflex band. It is also one of the most efficient band heaters available.
Some applications require both heating and cooling. With the advent of exothermic materials and heat generated by screw rotation, the proven Marathon Starflex band heater was adapted to provide both heating and cooling functions. Cooling tubes are placed in proximity to the heating elements to produce the Marathon Starflex Heat/Cool band. Due to its low mass, it can be cooled relatively quickly.
Installation of these bands is easily performed by opening the band, placing it around the cylinder and tightening a single screw. Large diameter bands are furnished with multiple clamping assemblies and multiple segments from grasping the surface.
Marathon Starflex band heaters are designed for use in barrel heating of extrusion and injection molding machinery, blown film dies and other cylindrical surfaces. Their configuration can be full for 360° coverage or any degree of partial warp. Internal bands to heat from the inside-out are also available.
