This paper examines a manufacturing technology behind graphite moulds designed for casting refractory and chemically active alloys following the patent of the Russian Federation No. 2585604 “Mould for centrifugal end shaped castings from refractory and chemically active alloys”. The paper substantiates the possibility to implement this patented technology and compares investment casting and green sand casting in application to small-scale (single-part) manufacturing. A case study of a cast central bushing made of the titanium alloy VT20L is considered. A feasibility study has been prepared to justify the application of green sand casting. A market analysis has been conducted and potential customers for the patented process have been identified. The authors substantiate the feasibility of using green sand casting to produce graphite moulds for small-scale or single-part casting of refractory and chemically active alloys, and perform a market valuation of the patent in view. A set of necessary equipment has been selected to implement the production of graphite moulds to match the employed process. A feasibility study has been carried out to justify the production of graphite moulds for casting refractory and chemically active alloys (per 2017 data). Thus, the required capital investment and production cost have been estimated. The authors also estimated a payback period, cost effectiveness and a market value of the process (patent cost).

This project was implemented under the Decree of the Government of the Russian Federation No. 218.3 dated 9 April 2010, State Contract No. 02.G25.31.0009.
