Description:
Cartridge heater is a kind of heating elements made of MgO powder
or MgO tube, ceramic cap, resistance wire(NiCr20/80). It is used to
heat in plastic injection moulds, dies, platens .
Feature
For those applications where a drilled hole is not practical, GME
offers square cartridge heaters. Unlike square cartridge heaters
from other manufacturers, our square cartridge heaters are swaged,
allowing them to be used in high temperature and high watt density
applications.
Square heaters are ideal for milled slots in long platens where
drilling a long hole would be too difficult. Square heaters are
also much easier to remove from a slot after extended high
temperature usage than removing a round heater from a drilled hole.
