Abstract
A method for uniform pressing and compaction of parts, comprising a
first step (I), in which the powders to be pressed are loaded into the mold,
with the lower male plugs (Y0,Y1,Y2) arranged in a preset position with
respect to the upper surface (A) of the central female mold part, so as to
form containment volumes (V0,V1,V2) for the powder to be pressed in each
region of the part; a second step (II), in which the upper male plugs (X) are
made to descend at a substantially low pressure until they make contact with
the powder deposited in the female mold part and then each individual
region of the lower male plugs descends synchronously with the upper male
plugs in order to arrange the centerline planes of each individual region on a
same plane, which will be the horizontal plane of symmetry of the finished
part; a third step (III), in which the pressure increases gradually and the male
plugs of the pairs of male plugs of each region move symmetrically toward
each other with respect to the horizontal plane of symmetry of the part until
final compaction occurs.
