Therefore, it is very important to obtain the best manufacturing castings through a mold with good property and process parameters. This study is to investigate the availability of using the equipments in the conventional copper-casting factory to EPC casting, and to find the relationship between pattern shape design, manufacturing parameters, casting quality (of EPC mold by using conventional casting equipment) and the dimensional precision. also evalualed to build up the requirements in EPC method obtain which obtains the better qrality copper casting via conventional equipments. Finally, the experiments also abserve and the of EPC copper casting , and the observation shows that the imperfections on the casting surface mostly come from the gas of thermal decomposition of EPC pattein and the difficulty of gas released into sand mold due to the pattern coating.
