Polymersymer consists of oriented crystallites called lamellae, with the c-axis aligned in the direction of extrusion or drawing, which are connected by oriented tie-molecules. The stiffness and strength of the material are related to the state and number of the tie-molecules. If they are tight in tension,

Fundamentals of Hydrostatic Extrusionlength of the billet is not limited as it is in conventional extrusion. Also, the frictional forces between the die and the billet tend to be lower in hydrostatic extrusion because the lubricant is forced, by the high fluid pressure, to flow into the interface. A low frictional stress on the die sur

Mechanics of Hydrostatic Extrusion. Because of the simplicity in handling, this method has been applied to many forming processes. When extruding an ideally plastic material with a yield stress Y through a conical die of an included angle α at a extrusion ratio R is given as follows when the friction coefficient between the die and
