1. There is no the exposed wire connection determines this heater is the internal cartridge heater, we have to say it that this cartridge heater working life is longer than the external cartridge heater and the manufacturing process is very complex

6. The cartridge heater is filled with magnesium oxide and compressed to avoid a short-circuit.

7. Good heat emission and the excellent control response.



According to whether have the exposed wire connection or not.

External cartridge heater: hard stainless steel wire elicit from the interior heater, meet the high temperature wire outside. This technology is standard.

Internal cartridge heater: high temperature wire elicit from the interior heater directly, this technology is high in the cost, but hard to broken line.

Soft lead wire cartridge heater: stainless steel soft wire elicit from the interior heater, latch the glass fiber sleeve outside .this technology is low in cost ,hard to broken line.



In the plastics industry cartridge heaters are used in hot runner system, small mould heating, plastic package, Medical equipment plastic, plastic injection molding machine nozzle heating, Package and cartridge is also used in the cigarette industry, footwear industry, thermoforming machinery.
