  • Process and apparatus for molding polymer sweep fittings
    Patent number: 6399006
    Abstract: A method and apparatus for producing molded fluoropolymer sweep elbows with straight threadable ends that minimizes distortion of the fitting. The apparatus comprises a mold core or insert that is comprised of multiple curved segments which are retracted from the mold individually. The mold core is divided into two or more pieces on a curved plane parallel to the curved central axis of the core and the segments thus formed are retracted from the mold by a combination of arcuate and translational motions to avoid distortion of the fitting ends.
