SUNENERGY CORPORATION
We manufacture and sell UV irradiating devices, UV lamps, and UV-LED light sources mainly for flat panel displays (FPD). We set up a new office in the Kobe Biomedical Innovation Cluster in March 2016 to enter the growing medical and biological fields. We can improve the wettability of a resin surface by UV irradiation, thus surface-modifying biological films for medical use and helping to improve the settling of stem cells. This optical surface treatment technology forms an oxidized film on the surface of titanium, which serves as substitute bone. The technology is expected to be useful in fields other than tooth implants.
Chimera Co., Ltd.
Our company manufactures ultra-high-precision metal parts on a made-to-order basis. We established our ultra-high-precision metal working technology based on the wealth of experience and know-how that we have accumulated through the years since our establishment in 1988. This technology helps us to meet a wide range of customer needs, from small lots (such as a single screw) to mass production. Our company produces 8,000 ultra-high-precision metal parts per month. The production of molding dies and mold parts is also within our scope of business. We can deliver these products in a short time, even when it involves machining difficult-to-machine material. We are also accelerating our expansion in the field of medical devices. We already have production sites for overseas expansion in Malaysia and Michigan State, and are currently considering doing business in Europe.
Ikegai Corp
We manufacture and sell machine tools (CNC lathes, machining centers, CNC horizontal boring machines), industrial machines (extruders, sheet forming machines, film forming machines), and engines (marine engines).
