  • Method of forming filter elements
    Patent number: 9364775
    Abstract: A method of forming a filter element is disclosed comprising introducing a mixture into a feeder, the mixture comprising a plurality of susceptor particles and a plurality of polymeric binder particles. The mixture is advanced through the feeder and into a die comprising an excitation portion where eddy currents are induced in the susceptor particles by subjecting the mixture to a high-frequency electromagnetic field, the eddy currents being sufficient to elevate the temperature of the susceptor particles to cause adjacent polymeric binder particles to be heated to at least a softening point. The susceptor particles bind with the heated polymeric binder particles in the die to form a coherent mass. The coherent mass is advanced out of the die and cooled to form the filter element.
