cartridge heater, compared with the double-head tubular heater, thecartridge heater is taken out from one end, and generally adopts a star-shaped connection method. There are also many manufacturers of cartridge heater manufacturers in Xinghua.
The cartridge rod heater is generally used for mold heating or air dry burning, mainly for heating the cartridge rod heater of the mold, directly into the drilling hole of the mold, and the outlet end is fixed with a gasket to prevent the cartridge rod heater from moving.
It is particularly important to note that the production of a rod heater should take into account the cooperation between the diameter of the tube and the aperture of the template. The diameter of the electric heating tube is too large, so that the electric heating tube cannot be filled into the hole position, and the expansion factor of the tube after heating is considered, which brings the later maintenance. Inconvenience; in addition, it should be considered that the pipe diameter should not be too small, and the vacancy between the large and the wall of the hole cannot be reserved, which affects the heat transfer effect and service life of the electric heating pipe.
