Binder system method for particular material

A method for forming a part by powder injection molding, comprising:

• (a) forming a green composition comprising a binder composition and an inorganic powder, wherein the binder composition comprises a polycarbonate polymer, an ethylenebisamide wax, and a guanidine wetting agent;
• (b) transferring the flowable green composition into a mold for a part;
• (c) heating the part to debind the green composition by reverse debinding;
• (d) heating the part to a temperature at which the powder is sintered.

• (b) transferring the flowable green composition into a mold for a part by injecting the green composition into the mold for powder injection molding;
• (c) heating the part to a plurality of elevated temperatures to debind the green composition by reverse debinding, wherein a first elevated temperature corresponds to the debinding temperature of the polycarbonate polymer, a second elevated temperature corresponds to the debinding temperature of the ethylenebisamide wax, and a third elevated temperature corresponds to the debinding temperature of the guanidine wetting agent.
• (d) heating the part to a temperature at which the powder is sintered.
