Abstract: Disclosed is a method of manufacturing a refrigerant distributor for air conditioning and a refrigerant distributor manufactured thereby. The manufacturing method includes mixing copper powder with 30-60 vol % of a binder based on the volume of the copper powder, thus preparing a mixture for injection molding, subjecting the mixture to injection molding using a mold, thus producing an injection molded body having the shape of a distributor, removing the binder from the injection molded body, and sintering the binder-free molded body in a sintering furnace at 800-1150° C. in a reducible or inert atmosphere, the method being thereby favorable for mass production owing to omission of additional mechanical processing and enabling the manufacture of a distributor having a smaller size, as for adaptation for the miniaturization of an apparatus, reducing loss of material, and leading to low manufacturing costs.

  Abstract: The present invention provides metal powder compositions for pressed powder metallurgy and methods of forming metal parts using the metal powder compositions. In one embodiment, the metal powder composition according to the invention includes a blend of primary metal particles, one or more liquid phase forming materials or precursors thereof, a lubricant and an organic acid that is capable of reacting with an oxide of a metal in the primary metal particles to form an organic metal salt that decomposes when the metal powder composition is sintered under reducing or non-oxidizing conditions. During a “delubing” step, the organic acid reacts with an oxide of a metal in the primary metal particles to form an organic metal salt that decomposes into a base metal or a metal-carbide during sintering.
