About Aishin Iron Works
Founded in 1940, Aishin Iron Works began by disassembling and maintaining fluid control valves at the Ehime Plant of what is now Sumitomo Chemical Co., Ltd. for the purpose of supporting the stable operation of our customers' plants we have continuously refined our technical capabilities to handle valves from any manufacturer or of any type.
Building on the core expertise developed through valve maintenance, we have expanded our technologies to encompass the manufacturing of large-scale machinery and crane-related equipment. Today, our products play a vital role in supporting social infrastructure — serving industries such as ports, power generation, shipbuilding, and steel — and contributing to the foundation of daily life.

Our corporate philosophy is “Enabling a Better Future for People and Society” Guided by this philosophy, we design and manufacture conveying machinery and equipment for paper and chemical plants.
Grounded in three core principles — “quality control” through fully integrated in-house production, “flexible response” to customer needs, and “sincere proposals” rooted in trust — we have established the technology and facilities to manage every process in-house, from raw materials to finished products, across a wide range of applications.
