FIELD: stomatology, more specifically, dieing metal blanks of tooth crowns. SUBSTANCE: hydrodynamic press includes body in form of cylinder filled with transmitting medium and accommodating semifinished product of metal blank on die; coupling; piston with hole. Installed in piston hole is plunger for axial motion under action of leverage system. Piston upper end has guide sleeve with lock for locking the plunger in its upper position. Piston wall before lower end of plunger has side hole for discharge of excessive transmitting medium. EFFECT: simplified design of hydrodynamic press, increased reliability and reduced power intensity. 2 dwg
