Abstract

A method of forming a body of a formable working material in an impact machine, which comprises an upper impact unit (2) with an upper ram (14), an upper punch (17), a lower impact unit (3) with a lower ram (24), a lower punch (27), and mould cavity for the working material between the punches when the punches are brought towards one another, is characterized in that downwards movable masses, which comprise at least the mass of the upper ram and the mass of the upper punch, and upwards movable masses, which include at least the mass of the lower ram and the mass of the lower punch, are caused to move towards one another and towards the working material in the mould cavity, that the masses which move downwards, including the upper punch (17) obtain a downwards directed velocity (v1) and those masses which move upwards, including the lower punch (27), obtain an upwards directed velocity (v2), wherein the movable parts have such masses and the velocities are so high that the momentums of the downwards movable masses and the upwards movable masses become essentially equally large, i.e. so that the following condition applies: m1 x v1 SIMILAR m2 x v2 where m1 is the total mass of the downwards movable masses during the stroke, and m2 is the total mass of the upwards movable masses during the stroke.
