A single-ended heating tube, also known as a single-ended electric heating tube or a cartridge electric heating tube, is a type of electric heating tube (tubular electric heating element). In the Chinese electric heating industry, there is a long-standing model name: M3. In the late 1990s, with the widespread use of electric heating tubes in China, their shapes became diverse. In southern China, this type of electric heating tube used in molds with a single-end wire was called a single-ended heating tube or a single-end electric heating tube, which is quite descriptive.

Application: Single-end output heating tubes are suitable for use in heating media where two-end connections are not possible, such as high and low temperature insertion heating for various sizes of molds and machinery equipment, including punch molds and other molds, plastic sealing machines, bottle cap sealing machines, continuous automatic sealing machines, cigarette-making machines, and more. Mainly include:

Used for drying wood, paper, dyeing, paint residues, etc.

2. Melting and heating of niter and other salt substances.

3. Melt low melting point alloys, such as lead melting furnaces, tin melting furnaces, etc.

4. Building Heating Solutions

6. Infrared radiation heating device.

7. Low-temperature electric furnaces, such as industrial electric furnaces with air circulation and electric furnace cabinets.

8. Heating equipment for oils, waters, other chemical liquids, and electroplating bath solutions.

9. Marine and Sea Water Distillation Unit.

10. Heating equipment for alkalis and acids.

11. Used in the food industry for baking various breads, biscuits, and pastries; serves as an electric heating device in a conveyor tunnel.

12. In the plastic products processing, extrusion equipment, and rubber products molding and vulcanization equipment.

13. Sterilization and disinfection equipment, such as sterilizers and disinfectants.

14. Motor vacuum varnishing equipment heating, wire winding drying unit, etc.

15. Various household electric heating appliances commonly used in daily life, such as electric stoves, electric ovens, rice cookers, electric wok, electric frying pan, water heaters, and electric irons, etc.
