--------------------------------------------------------------------***-------------------------------------------------------------------1 Hydrostatic extrusion Abstract -In this review paper we're study about the process of hydrostatic extrusion process their significance and early history and how this hydrostatic extrusion process is important for a material with the help of former review papers, exploration papers and some former reference books. In this process, the billet in the vessel is extruded through a bone by a liquid pressure medium rather of by the direct amusement forces with a ram.

This hydrostatic extrusion process minimizes the force conditions, allowing advanced reduction rates, faster pets, & lower billet temperatures. Disunion of the bones can be largely reduced by a film of pressurized lubricant amidst the bones face and screwing essence. On applying high pressures, the rigidity of material increases. Extrusion is a process where a material undergoes plastic distortion by the operation of a force causing that material to inflow through the perforation or die. The material adopts the cross-sectional profile of the bones and if the material has suitable parcels, that shape is retained in the final extrude. In hydrostatic extrusion, the billet is extruded through a bone via the action of a liquid pressure medium rather of the direct operation of the cargo through a ram. In cases of hydrostatic extrusion, the vessel is fully filled by a fluid. The fluid is also pressurized, and this provides. With the help of ram pressure act on the fluid and this process is occurring

LITERATURE REVIEW:
Progress of technology has caused the development of new accoutrements to fulfill new engineering demands, e.g., new blends, greasepaint of pottery and superconductors, etc. These types of new accoutrements are frequently delicate to produce or give shape them. Among the new processes that were developed in recent times to produce these new accoutrements, hydrostatic extrusion appears to have the topmost eventuality. The difference between the conventional extrusion and hydrostatic extrusion is that the ultimate uses fluid (high- pressure fluid) as pressuretransmitting medium rather of direct contact. During the extrusion, this fluid transmits a hydrostatic pressure to the billet, which can largely increase the rigidity of the extrusion accoutrements. The fluid also work as a lubricant between the bones and billet and reduces disunion. This process is able of banishing numerous delicate- to- deform accoutrements. The extrusion machine can be divided into seven corridors.

1.
The idea of hydrostatic extrusion was first established by Robertson,but the system was first experimented by Bridgman
2.
Laterally exploration and development work was carried out by pressure system in 1964. 1.
That can help the cracking of brittle material in simple hydrostatic extrusion. Following this, further exploration and trial was done at High Pressure Laboratory of the Academy lures of the USSR, as well as in the USA, and Japan. The disadvantage of simple hydrostatic extrusion is that the extrusion speed is wilful. Slater and Green

With this system, when the fluid pressure is inadequate to banish the billet, a fresh force is applied to the hinder end of the billet by a solid ram. Still, the length of the billet is also limited by
