  • Method for treating ceramic cores
    Patent number: 6808010
    Abstract: A method for treating an unfired, molded ceramic core comprises placing an unfired (green) ceramic core having a thermosetting and/or thermoplastic binder on at least one setter, placing the setter and the green ceramic core thereon on a conveyor, conveying the setter and the green core through the heating oven to heat the setter and the green ceramic core to an elevated superambient temperature at or above a softening temperature of the binder present in the green core. Heating of the green ceramic core in this manner conforms the core to a surface of the setter to reduce distortion of the core and improve yields of cores that are within preselected dimensional tolerances.
