We aim to become a company that is indispensable in different industries through our mold technology

The new Yamasei Corporation was launched in 2012. We have continued our predecessor’s commitment to sheet metal press molds, and we also design and manufacture injection-molding molds. We have been committed to producing the molds that are the basis for Monozukuri craftsmanship for more than 50 years, including the time of our predecessor. We now include the culture of the Vuteq Group, and we intend to grow even more. The Vuteq Group's basic philosophy is to open up the future with enthusiasm and sincerity. We aim to become a company that is indispensable to the automotive and other industries through its mold technology, and to continue working to produce molds.

- Use of information technology (IT)
IT is nothing but a tool. Our company considers this technique of making full use of this tool as a strength. We thoroughly use molding simulation and other CAE beginning with CAD/CAM. We also independently develop a system for controlling them in an integrated manner. This total integrated management (TIM) system is used to provide an information-sharing environment anytime, anywhere to support users.
