This technology possesses many advantages, such as high efficiency, energy saving, lowcost, friend environmental, etc. Based on the laboratorial research, a batch of sand cores was made and castings were poured successfully in factory, that proved the practicality reliability and applicability of this technology. This technology is very meaningful for improving present formidable working conditions of cold box core making technology.
