The metal tubular electric heating element is produced by straight pipe at the time of manufacture, and the cartridge heater and the double-head electric heating element are straight rod heaters.
What is the difference between a cartridge heater and a double-head electric heating element?
1. From the internal structure, the internal heating wire is different, and the production process is different;
2, from the power, the same size, because of the difference in process, the surface load of the single-head electric heating tube can be designed higher, such as air dry burning size: Φ12 * 200mm, single-head power (imitation import) can achieve 600W, The double head can only achieve 300W.
3. From the outline structure, the single head is one end wiring, and the double head is the two ends wiring;
4. Under the working environment requirements, the cartridge heater is suitable for working in an environment where wiring cannot be connected at both ends.
First, the use and power of cartridge heater?
1, size molds and various mechanical equipment plug-in heating
(1) General process: 1-4w/cm2,
(2) Imitation import process: 6-8w/cm2
