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 .
Cartridge heaters are most frequently used for heating metal parts by insertion into drilled holes. For easy installation, the heaters are made slightly undersize relative to their nominal diameter.
Stainless steel braid is designed to protect leads from abrasion against sharp edges. It is the most flexible Watlow protective lead arrangement.

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.
