| 1. A method of forming a body with desired shape of a formable working material through impact action in a forming operation,
the method comprising the steps of:
a) providing an impact machine, the impact machine comprising a machine stand and at least one movable carrier which contains
and carries a plurality of tool units, each one of which comprises a die having a mould cavity for the working material that
shall be formed,
b) placing a working material in a die when the carrier is in a position where the die is located at a filing station,
c) moving the at least one carrier in a horizontal plane such that the die in which the working material has been placed is
moved from the filling station to a forming station in which the working material is to be formed, and
d) at the forming station, forming the working material to a body of desired shape by striking the working material in the
die from opposite directions with movable masses that strike the working material simultaneously such that the kinetic energies
of the movable masses during the forming operation are essentially transferred to the working material in the mould cavity
and are so great that the working material is plasticised and flows out to fill all parts of the mould cavity, to form said
body with desired shape, the movable masses that strike the working material from opposite directions having such masses and
such velocities that the momentum of the movable mass striking the working material from one direction is essentially equally
large as the momentum of the movable mass striking the working material from the opposite direction.
