Small Cartridge Heater

Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of small cartridge heater in China, also supports custom service. Welcome to wholesale high quality small cartridge heater at competitive price from our factory.

The typical structure of a small cartridge heater(the most popular structure) is generally composed of 5 parts: insulator, sealing material, lead-out rod, filler, heating wire, metal sheath, and terminal. The number of coils varies depending on the power. and provide a great uniform distribution of heat, which considerably increases the long life of the heater as well as prevents the oxidation of the heater wire even at high temperatures.

The manufacturing process of cartridge heater is to thread the spiral heating wire into the steamless steel tube, copper tube or aluminum tube, Filling of the gap with an insulating and thermally conductive oxidizing medium such as crystalline magnesium oxide powder(alumina or clean quartz sand can also be used) by means of a multi-tube filling machine.Then use a shrinking machine to reduce its diameter to make the oxide medium more compact. Through this technical process, the heating value of the actual area of the single-head tube is increased. Compared with the electric heating element with the same large amount of heat, the tubular electric heating tube can save 5% of the electric heating material, and the thermal efficiency can reach more than 90%.
