Ceramic core is an abbreviation of a kind of ceramic core used in casting mould handicraft. As a commutator to form casting cabvity, the functions of ceramic core are to compose the inside structure of the casting and to guarantee the demands of measurement and accurancy of cavity with the help of section mould and mould case. Ceramic core uauslly used to form casting mould cavity which is hard to take shape and with complex apperances, and also as a special means to simplize handicrafting difficulty, lower cost and improve production acceptance rate. The precise ceramic core EC85 the company developed is a high-level casting mould ceramic production which adapts choice raw material of high quality, unique formula and formed technology, advanced production facilities as well as strictly in accordance with the regulatory system of ISO9001. It is mainly used to form many kinds of inside cavity and sophisticated mould cavity during the process of casting mould handicraft.
