With the development, manufacture and sales of piping materials with thermoplastic resins, (vinyl chloride and the like) principal materials that softens with the addition of heat as the core, AOC is diversifying its business that centers around plastic valves in which AOC boasts leading market share both domestically and worldwide, into neighboring areas including plant engineering.

Using technology involving thermosetting resin (Predominately Phenol Resin) hardened from heating, we sell sophisticated high value products essential for the manufacture of parts and materials in key industries such as the automobile, machinery, electricity, electronics and construction industries.

We are involved in basic research relating to synthetic resins, as well as research in a wide variety of fields such as semiconductors, biotechnology, and production engineering development for mass production and labor saving. We have prepared a system capable of swiftly injecting sophisticated high performance new products that respond to the needs of the next generation.
