Electric High Density Cartridge Heater With Stainless Steel Protective Leads

High Density Electric Cartridge Heaters With Stainless Steel Protective Leads

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 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. ​
