  • Method of using recycled pet flake directly in an injection molding process
    Patent number: 9421697
    Abstract: A method of processing PCR plastic is disclosed, the method including a step of providing a bulk quantity of flakes of PCR plastic having a particle size of about 10 mm or larger separating ferrous and non-ferrous metals from the bulk of flakes of PCR plastic, comminuting the flake to a particle size less than 10 mm, such as about 4 mm, and thermally treating the flake to reduce a moisture content therein. The process may further including mixing the thermally treated flake with virgin plastic pellet and processing the mixture directly in an injection molding device.
    Type: Grant
    Filed: March 6, 2015
    Date of Patent: August 23, 2016
    Assignee: Phoenix Technologies International, LLC
    Inventors: Lawrence Robert Deardurff, Henry A. Schworm

  • PROCESS FOR PELLETIZING PET
    Publication number: 20100117267
    Abstract: A pelletizing system and a method for pelletizing a polymer are disclosed. The method comprises the steps of compressing a quantity of polymer flake of a predetermined size to produce a pellet and heating at least one of the polymer flake and the pellet to remove contaminants therefrom.

  • Method for cooling post reactor polyethylene terephthalate flakes
    Patent number: 6825311
    Abstract: A process for cooling post solid-stating reactor PET flakes comprises conveying PET flakes from a solid-stating reactor to a first separator in the presence of air and water at an elevated pressure, separating the steam from the partially cooled PET flakes, and conveying the partially cooled PET flakes from the first separator to a second separator in the presence of air at an elevated pressure.
