Our cartridge heater filling machine has been specifically designed to address the complex structure of single-ended heating elements. Its primary function is the precise and compacted introduction of magnesium oxide (MgO) powder into metal tubes, ensuring electrical insulation and thermal transfer. Unlike universal filling machines, this equipment guarantees optimal centering of the heating coil through an electronically controlled vibration system. It is the ideal solution for manufacturers seeking to elevate the quality of their industrial cartridge heaters, ensuring uniform powder density from the welded bottom to the tube mouth.
