正英 Company Profile

Planning, design, and prototyping to mass production of health devices and equipment.

Sei-ei has celebrated its 27th anniversary since its establishment as a tape factory. Starting with the tape business as our foundation, we have expanded into various fields. It is meaningless to only seek what is always in demand; if what is needed does not exist, we have practiced researching, developing, and bringing it to fruition together as a company. As we celebrate our 27th anniversary today, we are engaged in the design and manufacturing of beds, as well as the design and manufacturing of vehicle interior and exterior parts, primarily led by engineers from manufacturing backgrounds, and we also handle prototypes related to seating. Furthermore, we are not limited to domestic production centered around our own factory; we have built strong cooperative relationships with overseas partners and are expanding our business areas in the development of imported SP products, proprietary products, and small miscellaneous goods, as well as overseas OEM production. We have made it our motto to be a company with human charm and vitality that attracts people. By empathizing with the ideas of our customers and employees, and approaching various fields with a strong curiosity without being confined to frameworks, we have become what Sei-ei is today. We aim to continue to make leaps forward as a comprehensive company that possesses human power, technical capabilities, manufacturing functions, and development functions.
