The Most Sought After Band Heater
Maxiband Heaters due to their rugged construction characteristics are highly recommended for plastic injection molding machines extruders and blow molding equipment. The band assembly is securely fastened to the cylinder by a low thermal expansion strap.Maxiband Heaters are constructed as sets each half consisting of a tubular heating element pressed into an extruded aluminum track.
Diameter: 3 1/2" to 60"
Mica heaters are efficient and economical solutions to the heating requirements of many applications. Mica heaters can attain a maximum sheath temperature of 900°F, but with different electrical termination styles, clamping mechanisms, and ability to accommodate holes and cutouts, mica band heaters are successfully used in many applications, but are mostly sought for in the plastics industry.
Aluminum Finned Cast-In Band Heaters are used as an alternative to Liquid Cooled Cast-In Band Heaters for heating and cooling the barrels of plastic extruders.
As a standard, Finned Cast-In Band Heaters are manufactured in aluminum alloys because this material provides very good thermal conductive properties. For applications requiring higher operating temperatures and/or higher watt densities, bronze or brass alloys can be used.
Precision machining of the inside diameter yields superior heat transfer between the heater and
the machine barrel, thereby ensuring uniform heating and cooling of the extrusion process. The heaters are secured to the barrel either by Stainless Steel Clamp Bands or by means of Bolt Clamping the heater halves together.
Finned Cast-In Band Heaters can be designed to meet the mechanical and physical constraints of existing extruder shroud systems. They are manufactured for Original Equipment Manufacturers (OEM) and maintenance (MRO) applications to customer specifications.
