40 years of experience in ultra-thin plate welding and reliable technical skills; achievements in precision welding processing [Precision Parts Welding]
We perform welding assembly of foil (ultra-thin sheets) and machined parts, as well as assembly of precision components. We weld components for energy equipment such as small vacuum chamber assemblies, semiconductor manufacturing equipment parts, and fuel cells used in high-temperature environments, ensuring no leaks or cracks in harsh operating conditions like ultra-high vacuum and low-temperature devices. We also weld medical device components such as implant parts and surgical instruments. 【Features】 - The finish after welding is at the level of machined parts. - Cost reduction. - Proposal for shortened delivery times. → Replacing the production of prototypes and small quantities, which were previously made by cutting or pressing into a single shape, with welding processing. ↓↓ For more details, please contact us or download the catalog ↓↓

Company information
Nissei Kiko Co., Ltd. has been engaged in precision welding processing, primarily focusing on stainless steel foil materials (ultra-thin materials), for 40 years since the founder encountered 0.05 mm butt welding, with the motto of being a pioneer in precision welding. In addition to stainless steel, we also handle welding of pipes with butt joints of 1.0 mm or less in materials such as titanium, Hastelloy, and Inconel, and we provide contract processing for precision equipment parts, including vacuum devices, semiconductor manufacturing equipment, ultra-low temperature devices, fuel cells, and nuclear-related components, from welding to assembly. From prototype development with a single piece to batch production of several hundred pieces, we offer precision, accuracy, and sincerity with the nimbleness characteristic of a small factory.
