Cartridge heater is made for high temperature application. Helical round resistance coil is placed around the solid Mgo tube filled with high temperature Mgo powder and compacted for faster and efficient heat transfer. Cartridge heater is used in heating applications by way of insertion into metal blocks via a series of drilled holes. The types of applications that are suitable for cartridge heater use includes injection moulding moulds, nozzles, T dies and extrusion dies. Cartridge heaters are manufactured in two basic forms – high density and low density. High density cartridge heaters are used to heat plastic injection moulds, dies, platens and so forth, whereas low density cartridge heaters are more suitable for packing machinery, heat sealing, labelling machines and hot stamping applications.
