▎ 摘　　要

NOVELTY - The high temperature resistant glass or ceramic heating ring has a heating ring frame (1) that is composed of a round tube (5), and an inner graphene heating coating (2) is brushed on the inner wall of the heating ring frame. The internal graphene heating coating is installed with two starting points (9), an injection molding machine screw (3) is sleeved inside the heating ring frame, and a conductive component (4) is matched and installed in the heating one side of the ring frame. USE - High temperature resistant glass or ceramic heating ring for injection molding machine. ADVANTAGE - The device is easy to install as a whole, and that is convenient for the staff to use that. The device has the advantages of flexible installation, high temperature insulation, fast infrared heat transfer, long life, and the production is not limited by the model and specifications, and saves electricity by 30 compared to the heating wire heating ring. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the high temperature resistant glass or ceramic heating ring for injection molding machine. Heating ring frame (1) Inner graphene heating coating (2) Injection molding machine screw (3) Conductive component (4) Round tube (5) Two starting point (9)
