COMPOSITION FOR MOLD CORE FORMATION

摘要

PROBLEM TO BE SOLVED: To provide a composition for mold core formation detachable/ removable after casting by being filled in fine pores of a mold when a molding with fine through-bores is obtained. SOLUTION: The composition for mold core formation 6 comprises a heat- resistant inorganic granular substance, an inorganic/organic fibrous substance, and a binder. This composition 6 is filled in the fine pores 4 ofϕ10 or less formed on a sublimation pattern 2 to be cast, and then the composition 6 is detached and removed after casting to obtain the molding with fine through- bores 4.
