Description:

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 is one of the 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)

Applications:

Usually, cartridge heaters are used to heat solids such as injection presses heating plates or various tools; On the other hand, they are also used for heating up water and gases under certain conditions. Especially, it is widely used in automotive industry. Cartridge heaters are also commonly found in the chemical, electronics, medical equipment, packing and nuclear industries.
