- Jun 16, 2020-

Quartz tube heating tube for plastic machinery, including a hollow cylindrical outer cover with a central opening at the two ends, a pair of insulating skeletons located between the two end faces inside the outer cover, the two ends are fixed on the insulating skeleton and open along the center A plurality of quartz tubes uniformly distributed on the circumference surrounds the reflective layer at the rear of the quartz tube. The heating wires are arranged in the quartz tube and are electrically connected to each other. A heat insulation layer is provided between the insulating skeleton, the reflective layer and the outer cover. The heat of the heating tube is concentrated in the central opening and is not dissipated. Compared with the existing heating ring, it has obvious energy saving effect, and the maintenance and installation are also very convenient.
