    ● Electric heater cartridge is a piece of equipment, made of MgO powder or MgO tube, ceramic cap, resistance wire(NiCr2080),High temperature leads, seamless stainless steel sheath(304,321,316,800,840) 

    ● Usually in tube form,that is used in heating applications by way of insertion into metal molds via a series of drilled holes. 

    ● Cartridge heaters are manufactured in two basic forms - High powerdensity and Low and medium power density. 

            High power density (heating surface power 10~25w/cm²), are widely used to heat Plastic injection moulds, Moulds, Platens and so on

            Low and medium power density (heating surface power5~11w/cm²), are more suitable for packing machinery, heat sealing, labelling machines and hot stamping applications. 

    ● The high-quality stainless steel sheath provides long-lasting protection, even in the harshest industrial environments. Its max power density can reach up to 40w/cm², and its maximum operating temperature can reach 800℃
