Compact and powder sintered body and these production methods for powder sintered body

摘要

Possessing with the binder resin where this invention, the slurry which includes with the raw materials powder and the binder resin and dispersion medium centrifugal forming inside the formation die, lies between production method of the compact for the powder sintered body, produces the raw materials powder and the compact which consists of the binder resin, and production method, and the raw materials powder and the said raw materials powder of the powder sintered body which sinters its compact connects the said raw materials powder, sinterring the compact and its compact which for the powder sintered body, become it is the powder sintered body which can.According to the manufacturing method method of the compact for the powder sintered body of this invention, complicated form being high-level, it is possible, to produce the compact for the powder sintered body which such as crack or damage is difficult to occur it is possible to produce the compact for the powder sintered body which can make high-level complicated internal constitution and form in addition with mechanical processing. As for production method of the powder sintered body of this invention, it is possible to produce, the powder sintered body which such as fuel injection nozzle for the Diesel engine possesses complicated internal constitution and form high-level.
