Abstract
Relationship between distribution of density of packed powder and green compact in two kinds of packing methods was studied. The shoe packing method and the mesh packing method were employed. The packed powders were compressed at 49 kN (7 MPa), 9.8 kN (14 MPa) and 49 kN (70 MPa).
It showed similar tendency between the packed powders and the green compacts in the density and its distribution: the green compacts, which were packed by the shoe packing method, were coarser and more widely distributed density than those of mesh packing method. It was found that the packing method affected the density and its distribution of the green compact, and also that the density distribution in the packing affected the friction between the particles and the die wall.
