1. 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.
2, 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.
3. Fill the electric heating tube 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 phenomenon of unevenness caused by manual filling of magnesium powder extrusion).
