A composite molding compound comprising a combination of metal and ceramic powders is disclosed. The powders are combined with a binder, a liquid carrier and other processing additives in a manner to provide uniform distribution of two phases in a material format that facilitates the molding of complex parts at relatively low pressures and temperatures using conventional injection molding machines. The products formed from these molding compounds may be designed with tailored physical and mechanical properties such as thermal conductivity, thermal expansion coefficient, density, elastic modulus and wear properties.

Metal/ceramic composite molding material

A novel process for preparing injection molding feedstock compounds in a continuous manner amenable to high volume manufacturing includes the steps of forming a mixture including metal and/or ceramic powders, a binder and a liquid carrier, supplying the components in a continuous manner to a twin screw extruder, forcing the homogeneous compounded mixture through an exit die, and cutting the extruded strand into pellets. The pellets are useful for shape-forming articles by various molding processes.
