Popis: In the Age of Modern Nonferrous Casting process, varieties of processes are being worked out. Castings are integral part of many Industries and they occupy more than 25% of the metal processes. As we look at this century, newer processes are evolving which contribute to the success stories of many product profiles. One of the important characteristics of a Casting process is aesthetics. With Aesthetics and development time, Sand Casting and Gravity Die casting are the major two process adopted by the Industries. These two processes have been used by majority of the Industries. However issues like poor finish due to improper hand pouring methodology and environmental conditions prevailing, the products coming out of these processes are not giving the requisite output, to say that mildly. Investment Castings are good but the cost of development and operating costs are not economical for Industries to adopt. An observation was made from several foundries and found V-process or Vacuum process could be deployed for same. As a pilot project couple of Industries started adopting this process and found that the process is giving excellent yield and excellent aesthetics with near net shape finish. As a result of newer process, the machining cost is cut down drastically and the process is environmental friendly as well. Sequence of operations and other finer aspects of V-process are dealt in detail.
