Two Factories Equipped with the Latest Equipment for Materials and Precision Molding
Kansai Factory

Kansai Factory mainly manufactures composite materials, including Epohard and Epocluster. Furnished with highly productive equipment, Kansai Factory delivers a stable supply of advanced base materials for molded insulators and precision molded products, in close cooperation with the Sales and Marketing Division, the R&D Division, and the Kanto Factory.
In the headquarters building, a vibration-proof laboratory supported by pillars extending to the subsurface bedrock serves as the facility for the R&D Division. Even the slightest vibrations will not reach the inside of the lab. No other small- and medium-sized enterprise has a similar lab. This facility, “Island on Earth,” provides a critically important base for our nanotechnology development.
