  • Extrusion method for ceramic honeycomb articles
    Patent number: 6800233
    Abstract: An improvement in a process of making honeycomb articles, which process utilizes a co-rotating, intermeshing twin screw extrusion apparatus to mix, screen, and extrude a batch of ceramic materials through a die, the improvement which comprises the steps of separating the mixing and screening phase from the extrusion phase, by passing the batch through a first co-rotating, intermeshing twin screw extruder or a mixer extruder to mix and screen the batch, and then directly passing the mixed and screened batch through a second co-rotating, intermeshing twin screw extruder or a pumping extruder to extrude said batch through a die assembly to produce a honeycomb article.
    Type: Grant
    Filed: January 30, 2002
    Date of Patent: October 5, 2004
