Single head electric heating tube is commonly used for mold heating or air dry burning, mainly for mold heating. It is directly inserted into the drilling hole of the mold, and the outlet end is fixed with a gasket to prevent the electric heating tube from moving.
. The diameter of the electric heating tube should not be too small, and too large a space between the tube and the hole wall should not be reserved, which will affect the thermal conductivity and service life of the electric heating tube.
