- 摘要：
PROBLEM TO BE SOLVED: To provide a method for producing a component having a thin part with a thickness of &le1 mm, having low surface roughness and having high sintered density and sintering strength without performing secondary working.
SOLUTION: The method includes: a stage where a molding material comprising metal powder and an organic binder is subjected to injection molding, so as to obtain a molded body and a degreasing-sintering stage where the molded body is degreased and sintered, so as to obtain a sintered compact. The above metal powder has the average grain size of 1 to 6 &mum, and is selected from stainless steel alloy powder, titanium alloy powder and/or alloy precursor powder forming a stainless steel alloy or a titanium alloy by sintering, and the ratio of the organic binder in the molding material is 40 to 50 vol.% of the whole quantity of the molding material. In the degreasing-sintering stage, the sintering maximum temperature is 900 to 1,200°C, the temperature rising rate in the temperature zone of 100 to 400°C is &le100°C/hr, and the temperature rising rate in the temperature zone of 600 to 800°C is &le200°C/hr.
