vormstantsimine (nii kuumalt kui ka külmalt), rakendades suurendatud deformatsioonienergiat ja -kiirust (üle 10 m/s) (vrd impulsslehtvormimine), a closed-die hot- or cold-forging process in which the stored energy of high-pressure gas is used to accelerate a ram to unusually high velocities in order to effect deformation of the workpiece; ideally, the final configuration of the forging is developed in one blow or, at most, a few blows; the velocity of the ram, rather than its mass, generates the major forging force (compare: high-energy-rate forming)
