Abstract：With the development of self-hardening resin sand,the traditional core molding process had been widely used in the production of large and complex castings.The automatic precision core molding production line using triethylamine cold core box method had been successfully applied to automobile parts casting,such as the whole casting aluminum condensing heat exchanger,engine cylinder block,cylinder head and other size accuracy requirements,complex process of small and medium-sized casting batch production.The development and application of the precision core molding process of triethylamine cold core box method was reviewed.This process was one of the important ways to realize green and intelligent production of sand mold casting.Further the rate of domestic production of raw materials and equipment is improved,the environmental protection measures in production is strengthened,the development of inorganic binder and related equipment and process development is the future development direction.
