Advances in Technology of Soluble Cores for Die Castings

AUTHORS P. Jelínek1, E. Adámková1, F. Mikšovský1, J. Beňo1 ABSTRACT A number of technologies is developed that substitute simple metal cores in the high-pressure casting technology. Soluble cores, namely on the salt basis, represent the highest prospect. The contribution gives the results of the production of salt cores by high-pressure squeezing and shooting with using a binder. Special attention
