Introduction of the Cartridge Heater:

      The cartridge heater has adopted the metal tube as the shell (including the stainless steel & copper), setting the spiral electric heating alloy wire (like the nickel-chromium and iron-chromium alloy) along the central axis of the tube, and then fill the gaps with magnesia sand of good insulation and thermal conductivity. In addition, sealed the ends with silica gel. This kind of metal heating element can not only heat the air, but also can heat the metal mold and liquids of all kinds.

Influence of cartridge heater heating process

       All the manufacturers wish to product the most durable cartridge heater. If it can be used for a long time, it can not only save the unnecessary expenses, but also improve the final quality of the heating element during the process. Since practice makes perfect. Heat treatment shall be needed if want to extend the service life time. Then what influence will be during the process? The deformation of cartridge heater after heat treatment is generally considered to be caused by cooling, which is not correct. For cartridge heater, especially the cartridge heater with special & complex techniques, the processing technology usually has a great impact on the deformation. If you compare the technology process of some of the cartridge heater, you may find that the faster heating speed usually lead to the great deformation.
