Automobile components use various rubber products such as suspensions, vibration-controlling materials around the engine, waterproof and dust-proof boots and sealing materials. A rubber injection molding machine is an essential production device for the automobile industry. As automobiles have developed, Japanese rubber injection molding machines have also developed. The STI-VR Series is the world’s best rubber injection molding machine, an accomplishment of which Sanyu is proud. It has achieved number one status globally in all specifications among competing products. VR-Z is an even more developed version of the VR series. The concept of the STI-VR-Z is to evolve from the "Made in Japan" that competes on technology to a "Made in Japan" that has a higher cultural level and has people at its core.
