摘要： A production method for a sintered part comprises preparing a metal powder and a binder composed of a thermoplastic resin and a wax, mixing the metal powder and 40 to 60 vol. % of the binder with respect to the metal powder into a mixed powder, and heating and kneading the mixed powder into a raw material. This production method further includes supplying a predetermined amount of the raw material in a hole of a die and compacting the raw material into a green compact having a predetermined shape by pressing the raw material by a punch. This production method further includes ejecting the green compact from the hole of the die, removing the binder from the ejected green compact by heating, and sintering the green compact by heating so as to diffusion bond particles of the green compact. The compacting is performed by pressing at a moving rate U of the punch, which is not more than a rate calculated from the following equation (1). In this case, ΔP (Pa) is pressing power of the punch, μ (Pa·s) is viscosity of the raw material, L (m) is a length of the green compact, and De (m) is a corresponding tube diameter. U=ΔP/(32μ×L)×De2 (1)
摘要翻译：烧结体的制造方法包括：将金属粉末和由热塑性树脂和蜡构成的粘合剂进行配合，将金属粉末和40〜60体积％％的粘合剂相对于金属粉末成为混合粉末，并将混合粉末加热和捏合成原料。该制造方法还包括将预定量的原料供给到模具的孔中，并通过用冲头压制原料将原料压实成具有预定形状的生坯。该制造方法还包括从模具的孔中排出生坯，通过加热从喷出的生坯中除去粘合剂，并通过加热烧结生坯以便生坯的扩散粘合颗粒。通过按照冲头的移动速度U进行压制（不大于由下式（1）计算出的速率）来进行压实。在这种情况下，DeltaP（Pa）是冲头的压力，mu（Pa.s）是原料的粘度，L（m）是生坯的长度，De（m）是相应的管直径。 U = DeltaP /（32muxL）xDe2（1）
