Ashizawa

What Ashizawa does

Ashizawa Finetech Ltd. (アシザワ・ファインテック株式会社) is a Japanese specialty industrial equipment manufacturer specializing in bead mills—wet and dry micro-grinding and dispersion machines used to process particles down to nano and sub-micron scales. The company traces its lineage to 1903 and was formally incorporated in its current legal form on December 16, 2002 as a spin-off of the machinery manufacturing business from predecessor Ashizawa Co., Ltd.; it operates today as a wholly-owned subsidiary of Ashizawa Holdings Co., Ltd. Its core technical differentiator is the trademarked Mild Dispersion® method, a process architecture that suppresses particle surface energy accumulation during milling to prevent re-aggregation and contamination, enabling sub-micron and nano-level particle size reduction while preserving particle characteristics.

The product portfolio spans lab-scale research machines (Lab Star Mini), high-viscosity wet production bead mills (Mugen Flow® MGF), mass-production nanoparticle dispersion systems (MAX Nano Getter® HFM, capable of several hundred kg per hour), and dry-process mills (Dry Star SDA1). Beyond equipment sales, Ashizawa generates revenue through a commissioned processing service (受託加工) running more than 500 test cases per year with a documented 80%+ customer satisfaction rate, plus technical consulting, joint development partnerships, and machine maintenance and support services. Headquartered in Narashino City, Chiba Prefecture, with a sales branch in Suita City, Osaka, the company employs 164 staff and is led by President Kato Atsuhiro (since 2023) under Chairman Ashizawa Naotaro.

Ashizawa serves a horizontally diversified set of enterprise end-markets including Battery/EV material manufacturers (its primary segment), Electronics and Semiconductor, Cosmetics, Pharmaceutical and Medical, and Printing and Coatings. The company maintains a Japanese technology partnership with Germany's NETZSCH-Feinmahltechnik GmbH, an applied development collaboration with Applied Diamond for nanodiamond dispersion, and ISO 9001 (2001), ISO 45001 (2021), Eco Action 21 (2004), and Health Management certifications. Distribution is exclusively direct B2B via the corporate website, on-site testing, commissioned processing, and industry exhibitions; operations remain Japan-domestic with no public revenue disclosure.
