See full text

A ceramic fiber band that can fulfill a plurality of functions in connection with the injection and/or extrusion process of an injection molding or extrusion apparatus (i.e. heat, cool, and insulate), thereby reducing overall energy costs and creating a safer working environment. The ceramic band, being an insulator and having heating and/or cooling elements with a faster response contained therein, exert the desired heating/cooling effect upon the barrel portion of the injection/extrusion machine thereby raising, lowering, or maintaining the temperature of the fluid plastic compound passing through the barrel.
