Completion of Third Photosensitive Materials Factory
The third photosensitive materials factory at Toyo Gosei Co., Ltd.'s Chiba factory has been completed. Tonoshomachi, where the factory is located, is 25 kilometer up the Tone River from Inubo peninsula, Choshi City, where on New Year's Day the "first sunrise" in the Japanese archipelago is worshipped.
In the first phase 1988 construction, bis-azide family photosensitive material manufacturing facilities, water-soluble photosensitive material manufacturing facilities, and alkaline developing solution manufacturing facilities were put into operation one after the other. In the second phase 1992 construction, operation began at the second factory, which is the main factory for positive-type photosensitive materials (naphthoquinone family).
This factory moved forward with a higher level of cleanness within the factory according to the needs of photosensitive materials users and laid the foundation for the top reputation the company enjoys among today's users.
The photosensitive materials factory completed in January 2001 uses the gravitation flow technique to move the material through the processes in order from above, first the raw material weighing room, then the reaction tanks, filtration equipment, crystallization tanks, the centrifuge separator equipment that separates solids and liquids, and the drying equipment. With the introduction of the DCS system, process management prevents operation mistakes and stabilizes quality. With an eye on the smaller labor force of the 21st century, we have also introduced robots.
These manufacturing facilities make full use of Toyo Gosei's 30 years of experience and track record with photosensitive materials. We are certain that with these facilities we will be able to provide the kind of quality that satisfies our customers.
This factory has 110 employees and with their average age under 30, this is a young factory. With the steady advance of semiconductor integration, we will tackle production with "fair, proactive, and rapid" always in mind.
