Abstract
Apparatus for carrying out the densification of powders, for example PTFE powder, characterized in that it comprises in combination; a cylindrical body whose diameter corresponds substantially to the diameter of the bar to be made and whose length corresponds substantially to the length of the volume occupied inside the cylindrical body by the powder in the uncompressed state; a free piston fitted to the cylindrical body at each of its extremities, each free piston being provided with organs to ensure the tightness with the cylindrical body and being provided on its face directed towards the inside of the cylindrical body, with channels connected to a pipe that it extends parallel to the axis of the cylindrical body and ends at its exterior; a cap that seals, in a watertight manner, each end of the cylindrical body, allowing the watertight and sliding way to pass through the corresponding pipe that is integral with the piston; and a source of fluid under pressure, such as water under pressure, which empties, through holes made in the caps, in each of the volumes that exist at the extremities of the cylindrical body, between the piston and the corresponding cap.
