Thanks to a new nonstick coating, these cartridge heaters?used for heating molds?help reduce downtime. The graphite-based coating is sprayed on the heaters and then baked. The coating is reported to eliminate seizing, provide resistance against scraping, offer higher watt density than split sheath heaters, deliver nonstick protection at high temperatures (up to 1200F), improve heat transfer, and extend heater life.
Because of the nonstick coating, there is no need to apply release agents before installation. No special bore requirements are necessary, since the heaters fit the same hole sizes required for standard cartridge heaters. Several options are available such as threaded fittings, mounting flanges or locating rings, rubber overmolds, BX conduit lead protection/ watertight stainless steel hose lead protection, post terminals, conduit box housings, bolt heaters, plugs, no-heat sections, and strain relief spring. All heaters are furnished with 12 inches of high-temperature (842F) lead wire as standard, and are available with internal type J thermocouples. The nonstick heaters are priced competitively with conventional heaters that aren?t nonstick-treated.
