Cartridge heaters, also known as insertion heaters provide superior heat transfer, uniform temperatures, resistance to oxidation and corrosion and long life even at high temperatures.
Cartridge Heaters can be made with various diameters, lengths, wattages, and voltages. They are widely used in molds and dies, platens, plastic molding and packaging machinery.
Used in sealing, extruders, hot runner molds, laminating equipment, process tanks, and die blocks.
Cartridge heaters have many options to meet your heating application needs.
