Cartridge heater is cylindrical electrical heating elements. Protected with a stainless steel sheath, their watt density can reach 63W/cm² and their operating temperature can go up to 800°C (1472°F) Mostly cartridge heater is used for heating up solids such as injection presses heating plates or various tools, cartridge heater can also be used for heating up water or gases under certain conditions. Widely used for manufacturing plastic and rubber parts in the car industry or in the food processing industry, etc . cartridge heaters are also commonly found in the chemical, electronics, medical equipment, packing and nuclear industries Various cartridge heater technologies are available. The choice of technology will depend on technical specifications required and the application. Unless you know exactly which product you are looking for, we will recommend you the best solution for your needs.

The heating part of the core of the cartridge heater is a nickel-chromium heat-resistant alloy wire, which is wound on a magnesium oxide core rod with excellent insulation and thermal conductivity. The heating wire and the shell are filled with magnesium oxide powder as an insulating material, and the air inside is compressed by the machine to make it into a whole.
After the main body of the cartridge heater  is completed, the fixing piece or thread can be installed according to the installation needs. The thread structure of the fixing piece is related to the heating tube installation method. Please contact our sales or technical personnel for the best solution.


Due to the various shapes and specifications, it is impossible to display all of them. If you need to customize various 
special-shaped heating tubes, please contact customer service.

Standard diameter size reference
Diameter in millimeters (mm): 2, 3, 4, 5, 6, 6.5, 8, 9.5, 10, 12, 12.5, 14, 15, 15.8, 16, 18, 19, 20, 25, 30, etc.
Diameter inches (inch): 1/4", 3/8", 1/2", 5/8", 3/4", 1", etc. (Remarks: 1 inch = 25.4 mm)
Note: High-power heating tubes are used in the mold, and mounting holes need to be reserved on the mold according to the size of the cartridge heater (or the outer diameter of the heating tube can be customized according to the size of the mounting hole). Please minimize the size of the heating tube and the mounting hole. Clearance. When machining mounting holes, the unilateral clearance is recommended to be within 0.05mm.

Note: The slash area in the figure represents the heating section of the heating tube

Note: Customize the hole depth of the mold according to the length of the heating part of the cartridge heater

If the hole is too deep, the heating part of the heating tube will be exposed after installation, and there is no good heat dissipation environment, which will damage the heating tube and may even cause accidents such as fire.

If the hole is too deep, the heating tube will be sealed after installation, and the lead part will fall into a higher use environment. Long-term use may cause problems such as a short circuit between the electrodes.

Note: The heating tube should be protected from moisture. It is recommended to start with a low voltage during initial use.
Storage and use in a high-humidity environment will cause the insulation resistance to drop, but after the power is turned on, the moisture in the heating tube will evaporate and the insulation performance will gradually recover. It is recommended to start with a low voltage.
