Cartridge heaters can be considered "component heaters" that are used to generate heat in many different applications. These process heaters are primarily used in mold and fit snug inside a cavity and helps heat solids by reaching high temperatures. Cartridge heaters have the versatility of being Cartridge heaters can withstand tough industrial usage; they can transmit up to 50 watts/in² heating capacity and are able to attain up to 300^oc sheath temperature. In order to facilitate installation and heat transmission, cartridge heaters are made 1/4 inches less than the nominal size of the receptacle hole, with a tolerance of +/- 0.002 in. Standard cartridge heaters are supplied with electrical leads that are connected internally within a 3/8 inch cold section. In excessively hot applications, the length of this cold section could be increased.
