The demand of quality improvement and reduction in costs from the user of die casting products increases every year. And, in order to fulfill the requirement, new technologies are developed as follows; (1) The high vacuum process reduces the gas content in the die castings and enables the welding of die cast products. (2) The high speed casting process enables larger and thinner product. (3) New die lubricant technique and optimization of cooling by CAE contributes to productivity improvement. On the other hand, these new technologies might give the die serious damages. Further cooperation of related manufacturers is necessary and indispensable for a further improvement in the future.
