1. sintered powder metal parts comprise:

  • Body, described body have two opposite surfaces, and at least one shaping surface in the described surface has teat, and described teat is towards the free end convergent of described teat;

    Wherein, the described free end generation plastic deformation of described teat, and described free-ended porosity ratio is less than the porosity ratio on the surface of the not plastic deformation in described at least one surface, thereby the size from described free end to another opposed surface is reduced in the tolerance range of nominal given size.
