Nakamura Mfg. Co., Ltd.
We are extending our business operations with aluminum machining and electron beam welding as our core businesses.
We are a metal part machining manufacturer established in 1945. We are extending our business operations by manufacturing and selling various parts, mainly to the semiconductor manufacturing equipment industry. This includes vacuum parts, parts with highly airtight structures, and parts with a high-quality appearance. We possess machining technologies using machining centers, NC lathes, general-purpose lathes, and general-purpose milling machines. We also possess wire cut EDM, electron beam welding, and vacuum brazing technologies for physical property processing. We combine these into a unique technology that we use to successfully manufacture parts that other companies do not handle.
[Company strength] Our motto is to be a "convenience factory." We have been manufacturing parts with various shapes for many years. We have confidence in manufacturing parts that are not available from other companies. This is done by welding and surface treatment, including outsourcing. We cannot compete with companies dedicated to specific fields. However, we have universal power for experimental to small-lot manufacturing of products with various materials, shapes, and processing types. Our universality is now highly appreciated among customers. [Business description] We manufacture various high-accuracy, high-quality parts with short lead times in high-mix low-volume production using combined technology. We provide these parts mainly to the semiconductor manufacturing equipment industry. This includes vacuum parts, parts with highly airtight structures, and parts with a high-quality appearance. We combine technologies for machining (machining centers, NC lathes, general-purpose lathes, and general-purpose milling machines) and physical property processing (wire cut EDM, electron beam welding, and vacuum brazing). The percentage of make-to-order production based on user designs is almost 100%. However, we also accept orders including design and assembly and are ready to have meetings at the design stage. [Industry] Metalworking [Strength of products/technologies] We create high-accuracy aluminum parts for gas and cooling water by using electron beams. These parts have channel structures inside them. Our company has two electron beam welding machines that can also deeply penetrate aluminum parts. We use these machines to create high-accuracy parts with complicated structures even in small lots, on a different level from welding-outsourced manufacturing. Our parts with internal channels in the welded structure have an overwhelming share in Tokyo Electron Group. We have marketed more than 15,000 bottom electrodes for 8-inch semiconductor etching machines over the past 15 years, but so far we have received no complaints from the market. [Representative's message] Our main user base is in the semiconductor manufacturing industry at present. However, we are confident that our processing technology using joining based on electron beam welding is widely applicable to many industries. Our physical property processing (processing utilizing the physical properties of substances) uses fine-level heat input from welding and wire cut EDM processing. Our company has been showcasing physical property processing at M-Tech and other occasions. We consider it to be a processing technology that is just as important as machining. We hope that this technology will be applied to even wider fields and contribute to global development. [Company structure for market development/overseas expansion] We have two employees dedicated to sales and two assigned to engineering and sales to meet various requests. We have not established a system for overseas expansion, but we support English in drawings and so on. [Market share/Ranking] Specific numeric data not available. [Awards and media coverage] [Awards] [Media] [Joint research and development] Our processing area determines equipment specifications, so we frequently hold meetings at the part design stage. [Main Clients / Business History (domestic)] Member companies of Tokyo Electron Group, TERUMO Corporation, Canon Inc., ULVAC-PHI, Inc., etc.
