  • Method for forming a polymer part
    Patent number: 9096009
    Abstract: Various systems and methods for forming a polymer part with utilizing heating fluid are provided. In one embodiment of the present invention a method for forming polymer includes heating the mold apparatus with a first heat energy source comprising heating fluid to a first mold temperature, and then heating the mold apparatus with a second energy source which is different than the first energy source. The second energy source heats the mold surface to a second mold temperature greater than the first mold temperature to form the part to achieve a desired surface finish of the polymer part.
    Type: Grant
