摘要： A forming die assembly for microcomponents includes a forming die, a plunger, and a punch. The forming die is formed with a cavity, a storage portion for storing a raw material with a metal powder and a binder having plasticity, and a punch hole that connects the cavity and the storage portion so as to form a gate therebetween. The plunger is formed so as to be slidably inserted into the storage portion and to fill the raw material stored in the storage portion into the cavity through the punch hole. The punch is slidably inserted into the plunger in the sliding direction of the plunger and opens and closes the gate by reciprocatory sliding. The punch closes the gate and compresses the raw material in the cavity into a green compact by sliding in the direction of the cavity.

摘要： The present invention relates to an iron-base powder for a powder core, wherein when cross-sections of at least 50 iron-base powders are observed and a crystal grain size distribution containing at least a maximum crystal grain size is determined by measuring a crystal grain size of each iron-base powder, 70% or more of the measured crystal grains are a crystal grain having a crystal grain size of 50 μm or more. According to the iron-base powder of the invention, a coercivity of the powder core can be made small and a hysteresis loss can be reduced.

摘要： The cross-sectional shape of a main part except for both end portions is generally divided into a lower arc surface extending along a base circle and an upper arc surface of which a top portion corresponds to the base circle. Side edge portions extending inward from the base circle are formed on both side surfaces of the upper arc surface. Curved edge portions which concavely curves upward from the side edge portions to end surfaces and continues to the end surfaces and chamfer portions extending from the end surfaces to the side surfaces which planes the edges and curves so that width thereof gradually narrows, are formed on both ends in a longitudinal direction.
