Production of metallic or alloy article

Abstract

Abstract PURPOSE:To obtain accurately a metallic or alloy article of a complex shape by kneading metallic or alloy powder with a specified org. binder, injection- molding the kneaded material into a molded body similar in shape to the desired end product, removing the org. binder and carrying out sintering. CONSTITUTION:Metallic or powder is kneaded with an org. binder having a composition consisting of, by weight, 0.5-2.5% methylcellulose as a bond basing on the amount of the kneaded material, 0.5-3% one or more kinds of compound such as polyols, ethers or esters thereof as a plasticizer, 0.5-3% one or more kinds of emulsions such as wax and stearic acid emulsions as a lubricating and releasing agent and 4-12% water as a solvent. The methylcellulose is prepd. by substituting methoxy groups for about two among three OH groups in each glucose residue in cellulose within the range of 27.5-31.5wt%.
