5.2 Description
Cartridge heaters are developed for high temperature applications.
Helically wound resistance coil is placed inside the tube filled
with MGO powder and compacted for faster and efficient heat
transfer.
Cartridge heater is a piece 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 ….
Cartridge heater plays an important role in electric heating
elements, which is widely used in industry mould heating. Compared
with the same heating element of high thermal, cartridge heater can
save 5% of electric materials, and heat efficiency can reach 90%.
Cartridge heater is cylindrical electrical heating elements with
stainless steel sheath, which watt density can reach 25 W/cm2 and
their operating temperature can go up to 800°C (1472°F)
5.3 Applications
1. Mold Heating
