Conclusions

  1. 1.

    The hydrostatic pressing technique makes it possible to dispense with the coining and intermediate sintering operations, which are essential in the manufacture of inserts by direct pressing.

     
  2. 2.

    Sintered shaping components produced by hydrostatic pressing at a compaction pressure of 60 · 107 N/m2 possess adequate strength and density. Even before sintering, the compacts can readily be machined on lathes.

     
  3. 3.

    Parts of less than 10% porosity produced by this technique can be successfully electroplated without any preparatory operations.
