A press for compacting a soft mass into a shaped workpiece. The press has a die adapted to hold the soft mass and having an open side, a compacting tool displaceable along an axis through the side into the die to compact the mass therein, a cylinder centered on the axis adjacent and outside the die, a piston shiftable in the cylinder along the axis and connected to the compacting tool, a relatively movable guide formation outside the die, offset from the axis, and fixed to the piston, a second guide formations fitting with the first formation, outside the die, offset from the axis, and generally stationary relative to the piston. The formations having engaging surfaces extending parallel to the axis, and actuator for displacing the piston axially into the die and thereby compact the mass therein. The guide-formation surfaces sliding axially relative to each other on axial displacement of the piston.
