abstract:-

Investment casting is an industrial process based on lost-wax casting. Investment casting is an advanced metal forming process used to produce metal parts in high quality, functionality and cost-effectiveness. Lost wax casting process is a one-to-one process in which one disposable pattern produces one metal part. When combined with modern production knowledge and technologies, it can be applied to produce parts of varying degrees of complexity, in virtually any volume and for the broadest possible spectrum of applications. A highly versatile casting process, lost wax casting has for some time been perceived as a comparatively expensive process. But when compared to alternative processes which require extensive welding or machining, an investment cast component can often dramatically reduce overall part production costs. Of course, investment casting is not the appropriate process for every metal part requirement. However, for many challenging part applications, investment casting offers a proven and cost-effective metal forming solution.
In this report we are specifically focusing on manufacturing of investment casting components, the actual process, design parameters, advantages, disadvantages and its applications in India and abroad and world market review of investment castings.
Quality is now the need of today’s industry. According to Peter drucker “Quality in a product or service is not what the supplier puts in. It is what the customer gets out and is willing to pay for". It allows the customers to have very little waste of raw material, avoid expensive machining costs and reducing overall costs. Investment Casting is indeed a Quality casting.
