Foundry is the process by which solid phased metal work can undergo changes by applying compressive forces as required to be performed and the forging is classified as HOT,WORM,COLD etc. The machinery used for the purpose of squeezing and for the deformation of material parts. In the process of forging different types like Drop forging machine, forging hammers, screw presses used for the purpose of axial and incremental forging process. The drop forging machines are used for translation motion, mechanical and hydraulic presses and for the purpose of rotational movement, longitudinal and radial rolling machine are used and the combination of pressure machines are also used. For casting purpose molten pour material is used. The purpose of forging is to improve the mechanical properties of the material by refining its grain structure improving grain flow and making more tougher and stronger which can be used without any problem. In forging like eye bolt and pick mattock are made and as all bars are annealed before forged. Hot forged manufacturing process is performed at 1150 degree centigrade for steel, 360 to 520 degree for aluminum alloys, and 700 to 800 degree centigrade for copper alloys, necessary to avoid strain hardening of metal. For the purpose of optimization of cost factors are taken which effects in the process and for this purpose installment of multi stage heating system is required.
