PRODUCTION METHOD OF OIL-IMPREGNATING SINTERED BODY

摘要

PROBLEM TO BE SOLVED: To provide a production method of an oil-impregnating sintered body capable of producing an oil-impregnating sintered body having a high oil content which is less likely to be dispersed.SOLUTION: A production method of an oil-impregnating sintered body includes an oil impregnation processing step for allowing a sintered body to impregnate an oil by immersing the sintered body containing metal powder into the oil individually. In the oil impregnation processing step, entry speed of the sintered body into the oil is slowed furthermore than take-out speed of the sintered body from inside the oil.SELECTED DRAWING: Figure 1
