It is the type of resistance used when the usage area is small and the heat requirement is high. The resistance wire is produced by wrapping around the ceramic axis throughout the entire resistance. Cartridge heaters are preferred as extruder machine heaters, plastic and rubber processing machine heaters, and many mold resistances because they provide high heat and are long-lasting resistance types. Vira Industry manufactures cartridge resistances in Ankara, Turkey and presents them to its customers.
