Barrels of plastic extruders, Injection molding  machines, Dies and Die heads of extruders.  Blow molding equipment,






  A  Mica core produces a thin, efficient heater.
  Heat from  the precisely wound Nichrome  element is
  quickly transferred to the working surface for fast heat
  up and response.
  Mica provides excellent dielectric strength and heat
  transfer capability for long heater life.

  The mica core is encased in a continuous corrosion resistant sheath and formed.
  All full mica band heaters are designed with closed ends to protect against contamination.
  Maximum sheath temperature is 350° C.


  • The heater indiameter[I.D] must be the same as the O.D. of the cylinder.
  • Secure Firmly: To compensate for normal expansion, retighten periodically.
    Cycling and normal metal expansion may cause the heaters to loosen.
  • Eliminate Contamination :
     Oil, plastic, dirt, etc., will carbonize and shorten heater life.
  • The heater should be rated for the highest voltage anticipated.
    Operation of a 220Volt heater on 240 Volt will raise the wattage by approximately 18%, increasing watt  density and reducing heater life.
  • Provide Proper Maintenance:
    - Tighten screw terminals firmly, but avoid excessive pressure.
    - Protect leads from abuse and abrasion,
    - Maintain temperature controls and accessories in good working condition to
       avoid   over
    - temperature operating conditions.
  • Do not open one piece band heaters or internal damage may result.
    If a Full Band Heater cannot be installed over the end of the cylinder, then use a Split Case or Half  Band Heater  for best results.
  • Check wiring for poor connections or open control if heater fails to heat when initially energized.
    Sustained high operating temperature may reduce heater life.
    If terminals oxidize, tighten connections and check for proper wire size.

 The uniqe construvtion of HANIL ELECTRIC HEAT ENGINEERING COMPANY cast band
 heater combines the exceptional life of a cast-in heater with the proven quality of a tubular

 The element utilized in the Cast 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 temperature
 for precise  process  heating.

 With the termination a significant distance from the part being heated and no other place for
 contaminants to enter, the Cast band heater 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°C attainable, the Cast 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.

   - Rugged, long lasting design
   - Excellent heat transfer from element to sheath and sheath to heated part
   - Virtually contamination proof
   - Uniform heat distribution sheath temperature
   - Easy installation
