Strength of Salt Core Composed of Alkali Carbonate and Alkali Chloride Mixtures Made by Casting Technique

Jun Yaokawa, Daisuke Miura, Koichi Anzai, Youji Yamada, Hiroshi Yoshii Abstract The strength of four binary systems NaCl–Na2CO3, KCl–K2CO3, KCl–NaCl and K2CO3–Na2CO3 was investigated in order to develop expendable salt core for high pressure die casting processes. Four point bending test was conducted to determine the strength of specimens made from molten salts by using the permanent mold casting technique.

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
