Standard Design Industrial Electric Band Heater for extruder
machine heating element
Description:
1) Electric band heater is medium-to-high temperature heaters that
can deliver up to 1200°F. The nickel-chrome heating cores of these
durable heaters are placed inside interlocking ceramic tiles that
are assembled like a brick wall.
2) A ceramic fiber insulating mat and a stainless steel jacket
cover this assembly. This construction makes ceramic heaters
flexible and highly energy efficient. An energized ceramic heater
that operates at 1200°F internally will have around 400°F on its
outside shell. Ceramic heaters consume 20 % less energy than band
heaters that are not insulated.
3) Band heaters are used in plastic processing industry for keeping
the nozzles of injection molding machines hot. Nozzle heaters are
manufactured from high quality mica sheet or ceramic, and have
Nickel Chrome resistance. Nozzle heaters are covered by metal
sheathing & can be rolled to the required shape. Band heaters
operate efficiently when the sheath temperatures are kept below 280
degree centigrade. If this temperature is maintained, the life of
the band heaters gets long.
Specification:
1) Use condition:environment temperature -20~+60 degree C
2) Leakage current:<0.5MA
3) Insulation resistance:>=5M
4) Ground resistance:<0.1
5) Voltage resistance:no electric breakdown for 1 minute under
1500v
6) Temperature endurance:500-800 degree C
7) Power deviation:+5%-10%
GME ceremic band heaters have the below point:
1) Applying imported ray materials to ensure operation conditions
of components under higher temperatures;
2) Using special manufacturing processes to enhance the heat
radiation effect for components;
3) Good electric performance to meet the safety requirements of
equipment;
4) Taking the lead in manufacturing processes in the electric
heating industry to ensure the longer service life of electric
heating parts and components
