Abstract

Procedure for compacting materials in powder form for parts to be sintered, according to which a mold die is loaded with the powder and then at least one piston is put into operation to exert the necessary pressure on the powder in the die to compress the powder slowly characterized in that the piston is driven until the powder in the die reaches a predetermined density and is then temporarily removed from the die then the piston is thrown violently against the die at high speed to acquire a high enough kinetic energy to compress the powder in the die additionally until a final density considerably higher than the predetermined density is reached.
