Corporate
Profile

[Company strength]
We have a large number of qualified technicians in the fields of boiler welding and aluminum welding. We have installed the largest specialized factory for buff polishing in Western Japan as well as various automatic machines. We have also constructed a semi-clean factory to conduct electrolytic polishing in a clean environment. We deliver high-performance, high-quality products via our integrated operations covering from welting to canning and polishing.



[Business description]
We mainly handle piping works for general piping, semiconductors, sanitary piping, and so on. We also design, manufacture, and install industrial equipment, pressure vessels, and tower tanks for various plants. We have advantages in integrated manufacturing of containers and plant piping covering from design to manufacturing, canning, and grinding of Class I and Class II pressure vessels. This is done by making use of our 70-year track record of deliveries to major chemical manufacturers and our accumulated technology.

[Strength of products/technologies]
We independently developed manual diaphragm-type electrolytic polishing (NEP), which combines buff polishing technology and newly developed electrolytic technology. This has achieved homogeneous electrolytic polishing without unevenness. It can be applied to large-scale products and can be used installation work sites. We also independently developed a new paste-like detergent to completely remove surface residuals such as buff lees and oil, which significantly influence the quality of electrolytic polishing. This has succeeded in drastically improving the quality of electrolytic polishing. We have a long track record and extensive achievements in the field of aluminum welding. We have pursued oxidation film removal, preheating temperature and welding material management, and so on, and achieved high-quality back bead welding in butted-end welding.

[Representative's message]
We independently developed manual diaphragm-type electrolytic polishing (NEP), which has the capability and flexibility to realize what conventional electrolytic polishing could not achieve. We have confidence in developing new demand in the field of medicine and semiconductors while taking full advantage of our equipment. This includes our semi-clean factory that enables work in a clean environment. We want to take on all kinds of challenges, including advancing into Asia where nano technology is increasingly being introduced, as well as in Japan.

[Company structure for market development/overseas expansion]
We hope to expand our business to the medical and food industries. At the same time we will advance improvements of our dedicated can manufacturing factory for stainless steel, train engineers, and improve our buff polishing and electrolytic polishing technology. We will also expand demand for our traditional aluminum welding technology to other industries rather than focusing on a single manufacturer.

[Market share/Ranking]
We possess the largest buff polishing factory and the greatest number of buffing technicians in the Shikoku region.
