Choe Chol Min, section leader from Faculty of Materials Science and Technology manufactured centrifugal compressor impeller using FDM and investment casting.
Centrifugal compressor impeller, which enables to enhance engine output and combustion efficiency, is very difficult to manufacture as it’s very thin and propene is twisted.
He proposed a new method for manufacturing centrifugal compressor impeller using FDM and investment casting, and a scientific method for raising the extraction rate in casting up to more than 90% by fixing reasonable indices of investment casting process based on the optimal indices of FDM process and simulation analysis.
His paper titled “Manufacture of centrifugal compressor impeller using FDM and investment casting” is published in the SCI magazine, “International Journal of Advanced Manufacturing Technology”.
