The present invention relates to a metal powder compression tool for forming compacts for sintering, including a first punch (15) adapted to compress powder located in a die ( 10). The clearance between the punch and the die is greater than the radial expansion of the punch under the desired compression effort, and lower than the mean size of the powder grain.
La présente invention concerne un outil de compression de poudres métalliques, permettant de former des briquettes destinées au frittage et comportant un premier poinçon (15) conçu pour compresser la poudre se trouvant dans une matrice (10). La distance entre le poinçon et la matrice est supérieure à l'expansion radiale du poinçon sous l'effort de compression voulue, et inférieure au calibre moyen de la poudre.
