About us

Ashizawa Finetech Ltd. has been consistently pursuing state-of-the-art technologies, particularly in the field of grinding and dispersing fine particles, so that our customers can develop and mass-produce high value-added materials that utilize our technology. Through these operations, we have a target to contribute broadly to the development of society and the improvement of our global environment together with our clients. With this target in mind, we re-made our company in 2003, the 100th anniversary year of our original founding.

My wish is to make our company “one of the most venerable but most innovative companies.” To this day, we have been repeatedly taking on new challenges and generating innovations in response to the changing times, while building cooperative relationships with companies outside Japan. With our deep gratitude for the expectations from our clients, we will continue to steadily advance and evolve as a leading manufacturer.

Technical Partnership Supporting Quality

Since 1984, Ashizawa Finetech Ltd. has had a technical partnership with NETZSCH, the world’s leading German manufacturer of grinding and dispersing machinery such as bead mills.
In Japan, Ashizawa manufactures, sells, and provides maintenance of NETZSCH products and NETZSCH offers customer support outside Japan.
With our quarter century long partnership, including mutual dispatching of technicians and other cooperative operations, we will continue offering state-of-the-art Japanese and German fine particle technology.
