Mesh resolution consideration for the viability prediction of lost salt cores in the high pressure die casting process

Mesh resolution consideration for the viability prediction of lost salt cores in the high pressure die casting process

B. Fuchs and C. KörnerPublished Online:February 10, 2014pp 24-30 Abstract High pressure die casting is limited in its geometry since a lost core technology as with sand or low pressure casting is not state-of-the art. Using lost cores made from sodium chloride may be a solution for high pressure die casting. Due to the high dynamical forces
