  • molten metal in a liquid state is filled in a cylinder tube in which a push rod is coaxially arranged.

  • the push rod is provided to effect axial reciprocation and rotation about its longitudinal axis.
  • a valve surrounding the push rod and slidable on the inner wall of the cylinder tube while overcoming a frictional resistance divides the cylinder tube into upper and lower chambers. Depending on the axial displacement direction of the push rod, the valve opens and closes, allowing or blocking the flow of metal between the upper and lower chambers.

  • the high shear forces present in the partially solidified phase state in the kneading process cause, in addition to the comminution of forming dendritic branches and the higher ductility thus achieved, a fine dispersion of the nanoparticles which is required for their strength-increasing effect.
