Apparatus for controlling the temperature of plastic materials using a ceramic fiber band isolated vacuum casting having heating and cooling elements.

摘要

An apparatus (20) for controlling the temperature of plastic materials in a fluid state when flowing through a head (22) and to isolate said head (22) comprising a ceramic (10) band having an outer surface (80) , an inner surface (82) and having a thickness, the inner surface (82) is in communication with the outer surface of the head (22), at least one heating element (40) and / or cooling elements (50, 52 , 54), wherein said element serves to provide various temperatures to the head (22) thereby controlling the temperature of the plastic materials flowing through the same, the band (10) acts as an insulated head (22), characterized in that ceramic band (10) consists of a fiber formed in vacuo, and the cooling elements (50, 52, 54) comprises steps a recess (84) of the inner surface (82) that allows the entry and exit air head (22), causing an effect re frigerante paraser exerted on the head (22).
