Starflex Band Heater
Brand: Backer Marathon IncThe Backer 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 Backer 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 Backer Marathon Starflex Heat/Cool band. Due to its low mass, it can be cooled relatively quickly.
We also manufacture cool only bands in a configuration similar to the Heat/Cool band. Cool only bands are manufactured with stainless steel tubes to meet a wider range of temperatures.
Features- Starflex heaters are manufactured by hydraulically pressing a high temperature heating element into a precision grooved aluminum channel
- The heaters are clamped in place with low expansion stainless steel straps for intimate contact with the part. The aluminum channel offers low mass and high thermal conductivity for fast heat up
- These same characteristics provide excellent cool down properties as well
- Starflex bands are also available with water cooling, both as a cool only band and a heat/ cool band
- Used on extruders, injection molding barrels, blown film dies, and other applications requiring rugged, long life heaters
- Heaters open completely, allowing easy installation and eliminating the need to remove other items from the barrel
- Durability of a cast-in heater at a fraction of the cost
- They are replaceable, unlike cast in heaters that require replacement of the whole heater
