In the blogs on extrusion and its types- Direct extrusion & Indirect Extrusion, it was noted that the major drawback with direct extrusion is the frictional forces acting on the billet. Accordingly, one can either try backward extrusion or can move ahead with hydrostatic extrusion. Hydrostatic extrusion is basically type of direct extrusion, wherein the billet is confined in sealed chamber surrounded by pressurized fluid. The force delivered by the ram pressurizes this fluid, which further applies to the surfaces of billet. As the ram moves forward, it in effect applies force on the fluid, which causes displacement of billet through die, extruding the metal part.
