  • HIGH SPEED CARBON FIBER CHIP EXPANDER
    Publication number: 20190016068
    Abstract: A carbon fiber sheet molding compound expander system incorporating a high speed cutter and an expander. Carbon fiber tow is cut to desired length, and the carbon fiber chips are delivered to the expander to expand and randomize the chips by transvectors of the expander. The expander opens up the chips in a way that allows resin material to contact individual carbon fibers.

  • Method of powder coating plastic substrates
    Publication number: 20130004675
    Abstract: A method for powder coating plastic substrate. The substrate in one embodiment is a formed part for a vehicle made from a polypropylene base, polyolefins or acrylonitrile butadiene styrene. The method also further involves providing a conductive adhesion promoter, such as a chlorinated polyolefin that includes a conductive carbon black filler. A powder coat material is applied at a later step and then is melted onto the substrate creating a finished part having a high quality finish.
