Abstract
In a method for injection molding of metallic mixtures, a metallic substance with a high melting point is mixed with a metallic substance having a lower melting point that serves in part as a binder material, and the mixture may be blended to form a homogenous feedstock for injection molding, or the mixture may be introduced directly into an injection molding apparatus.
Claims22
A method for injection molding metallic mixtures, comprising:
- mixing a first metallic material and a second metallic material to form a mixture, the first metallic material having a higher melting point than the second metallic material;
- applying heat to the mixture to establish the temperature of the mixture above the melting point of the second metallic material and below the melting point of the first metallic material to form a slurry;
- and
- using injection molding to form a molded object from the slurry.
