Nihon Seiki Co., Ltd.

Machining and plant design are the two pillars of our business, which are augmented by our welding technology. 

We are a production machine manufacturer of peripheral equipment for machine tools, semiconductor manufacturing equipment, and other various industrial tools and devices. Our business centers on the design and manufacturing of oil and natural gas production equipment. We have a mechatronics division that makes machining tools and a plant division that designs and manufactures oil and natural gas production equipment. We have an integrated system in both divisions that allows us to handle processing from development and design to material procurement, manufacturing, inspection, delivery, installation, and maintenance. Our strengths also include welding technology for piping works for geothermal well steam separators in geothermal power plants. This can only be performed by a company licensed under the Electricity Business Act.
