Abstract

PURPOSE: To smooth the surface of the extruded material obtained by the hydrostatic extrusion under a condition that the lubricative pressure medium, like as the castor oil, filled in the hollow cylindrical container fittingly attached to the tip of the extrusion dies, is heated to a specified temperature on purpose to reduce the viscosity.
