[Technical News vol.7] Introduction of the Vietnam Factory

[Technical News vol.7] Introduction of the Vietnam Factory

Providing quality that is no different from Japan on a global scale! Introduction of our factory in Vietnam.

Ohno Seiko's factory in Vietnam operates with a workforce similar in scale to that of Japan. The purpose of establishing this factory is to "achieve the same manufacturing as in Japan on a global scale." It was not created solely for the purpose of low labor costs or low procurement costs in Asia. Many of the young leaders working in this factory are members who have gained experience at Ohno Seiko's factory in Nishio, Japan. They have learned Japanese-quality manufacturing at the Japanese factory and are creating a process to realize that in Vietnam. The interior of the Vietnam factory is also well-maintained with 5S practices, and there are almost no employees leaving, allowing the factory to operate with high motivation. The parts that Ohno Seiko supplies to domestic customers are increasingly being produced at the Vietnam factory, and after quality inspection at the Nishio factory, they are delivered to customers. *For more details, please refer to the PDF document or feel free to contact us.*
