Cartridge heater often considered as component heater has a heating coil wounded on a ceramic core and are cylindrical-shaped, heavy-duty Joule heating element. Electricity flows through coil when two or three-phase voltage is applied. The electricity heats the coil and, subsequently, the cartridge sheath. The watt density (in Watt/inch²) depends on the number of spirals or turns per inch. These heaters provide a suitable, reliable and competent method of applying concentrated heat to solid metal components to high temperatures, particularly where compact, insert type heating is desirable.
