A single-head heating tube, also known as a single-head electric heating tube or a spring tube electric heating tube, is a type of electric heating tube (tubular electric heating element). In the electric heating industry in China, it has a long-standing model name: M3. In the late 1990s, with the widespread use of electric heating tubes in China, many shapes of electric heating tubes emerged. In southern China, this type of electric heating tube, which has a single wire exit for molding, is called a single-head heating tube or a single-ended electric heating tube, quite descriptive.

Application: Single-ended lead-out electric heating tubes are suitable for operation in heating media where two-end wiring is not possible, such as high and low temperature insertion heating for various sizes of molds and machinery equipment, including stamping molds, other molds, plastic sealing machines, bottle cap sealing machines, continuous automatic sealing machines, cigarette-making machines, etc. Mainly include:

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

2. Melting and heating of nitrate of potash and other salts.

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

4. Building Heating Solutions

6. Infrared radiation heating equipment.

7. Low-temperature electric furnaces such as industrial electric furnaces with air circulation, electric furnace boxes, etc.

8. Heating equipment for oils, waters, and other chemical liquids, as well as for electroplating tank solutions.

9. Marine and Desalination Distillation Units.

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.

In plastic product processing, molding, extrusion equipment, and rubber product mold pressing and vulcanization equipment.

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

14. Motor vacuum varnishing equipment, heating systems, and insulated wire drying units.

15. Various household electric heating appliances for daily use, such as electric stoves, electric ovens, rice cookers, electric wok, electric frying pan, water heaters, and electric irons.
