In our production of a broad range of ring gears, we use an integrated production process that includes cold-rolling of materials, cold bending, flash-butt welding, and gear cutting. We are capable of small-volume production of many items. Awarded the grand prize of the Small and medium-sized enterprises IT Management Power Award / the grand prize of the Minister of Economy, Trade and Industry Award (of the Japan Monozukuri Award) (both in 2009)

With the motto of “corrosion resistance (brightness) and shine with stainless steel”, we have developed and promoted “Removing Welding Burns Method by Neutral Salt Electrolysis” that is friendly to both people and the environment to remove welding burns,rust and dirt on stainless steel surfaces without using poisonous and deleterious substances. Also,we have developrd new applications of electrolytic method and finally, it has been evolved into a surface modification method. of "Ultra Passivation" that is effective in preventing pitting corrosion and stress corrosion cracking, which can be said to be a fatal defect of stainless steel. We are R & D type company. At the same time, we established a new business to be entrusted with "Ultra passivation treatment" as a measure to improve corrosion resistance and prevent stress corrosion cracking in operating food machinery and chemical plants, and are developing it on a country-wide basis. Such aggressive management was recognized, and at the end of 2017, it was selected by the Ministry of Economy, Trade and Industry as a “regional future leader company”. There has been no decline in our desire for research and development. For example, we recently have made it possible to remove welding burns on a thick plate of 10 mm or more in thickness, which was impossible with electrolytic method alone, by combining grinding and electrolysis.

Since started our business in 1921 as a wood pattern maker for castings, we have expanded business activities into various related technological fields.  By fully utilizing our craftsmanship and CAD/CAM technology, we provide various products such as casting dies and molds, welding tools for car body assembly and various castings consistently from design, manufacturing to trial.

We won devoted following among our clients by integrating system covering developing, designing, prototyping and production through the auto parts manufacturing, since our establishment in 1953.We are providing products matches to social needs, such as our product for house related companies "clasp for reinforcing carport which is home use". This has been certified as "Only one company" from Hiroshima Prefecture.As the proposal-oriented company to other industries with high quality and lowering the cost, we will strengthen the power that can be able to correspond to the customer's demand flexibly by utilizing our human resources, technology and equipment. In the future, we are aiming to be the enterprise with a sense of existence that it is possible to contribute to all industries.

We apply dissimilar materials according to the purpose (thermal spraying and welding) to the part where surface modification (Abrasion resistance, corrosion resistance, rust prevention, heat resistance, regeneration, etc.) is required to improve the quality and extend the lifetime. We can provide a wide range of services from new products (material selection to application ) to repair products (regeneration, life extension). With the technology and experience cultivated over many years, We provide an optimum proposal.
