The heat in the cartridge heater is mainly realized by the electric resistance wire, and the electric resistance wire is spiral. When the spacing is different, the heating is different, the spacing is close, and the heat is high. vice versa. However, the quality of the process will also lead to uneven heating of the cartridge heater. There are several main points, I have organized as follows:
1. The quality of the heating wire is not good, resulting in uneven spacing of the wire after compression. It will directly lead to uneven heating of the electric heating tube, so the manufacturer must purchase high-quality electric heating wire. This will create a good quality brand with good quality.
2. Try to make the resistance wire evenly distributed during processing. Especially when winding the wire, it must be wrapped around. Otherwise, the fever will not be uniform.
3. Fill the cartridge heater with a sufficient amount of magnesium powder to make the filling in the tube dense, and then compress it with a tube shrinking machine. The above is the common method of uneven heating of the cartridge heater. If you encounter uneven heating of the cartridge heater, you can refer to these three items to make the simplest judgment. If these methods can be eliminated, you can directly inquire.
However, due to the limitations of its materials and processing technology, it is necessary to pay attention to its characteristics in the mold design.
First, the mold cartridge heater is generally a dry burning tube, so you must control the temperature when working, preferably not more than 150 degrees.
Second, the mold cartridge heater must be closely attached to the mold hole, so that the heat conduction effect is good, and the service life of the cartridge heater is also very good. The size of the heating tube of the cartridge heater produced by Yancheng Huajiang can be accurate to ±0.08. Mm.
Third, the general mold heating tube usually has a long cold end at both ends, and can not play the role of heating. Therefore, it is recommended to use the imitation imported mold cartridge heater produced by our company. It is characterized by only one end of the cold end. And the cold end is generally about 1CM.
