Water-soluble ceramic core plays a key role in investment casting, especially the castings with complex inner cavity structures or high dimensional accuracy. This paper introduces recent research progress on the water-soluble ceramic core by injection molding technology systematically. A comprehensive review is made on the research advancement on the process and their influence on the microstructure, quality and performance of the water-soluble ceramic core. The key process includes plasticizers preparation, the choice of composition as well as particle sizes of inorganic salt binder and ceramic powder, mixing process, injection molding, degreasing and sintering, waterproof treatment, etc. This review provides technical guidance for the development of high performance water-soluble ceramic core. Finally, several main development trends of the water-soluble ceramic core in the future are concluded based on the previous analysis. In particular, emerging nano-material and technology as well as computer simulation technology will provide necessary support in the development of high performance and low cost core.
