ナミテイ Company Profile

Pioneers of Deformed Wire: We propose and provide deformed steel wire materials and deformed metal parts tailored to your needs.

Since its establishment in 1947, we have been manufacturing and selling steel wire products through drawing and rolling processes, and now we offer integrated production from cold-formed components to metal parts produced by pressing, shearing, and machining. In particular, we excel in the production of deformed coil wire with irregular cross-sections, and our strength lies in our ability to consistently produce unique deformed metal parts utilizing these irregular wires. Compared to powder sintering and precision casting methods used for manufacturing deformed parts, our deformed metal parts produced entirely through plastic processing at Namitei possess excellent toughness, strength, and smooth surface characteristics, making them widely adopted in sliding components and thin-walled deformed parts. To leverage the cost advantages of continuous processing, we propose specifications that mix functional applications and processing characteristics to meet our customers' needs.

Business Activities

<Automotive Parts Delivery Performance> Cold-formed components such as relay terminals, seat belts, seat systems, engines, transmissions, vehicle systems, and various weights, as well as press-shear components. 2024 performance (monthly production of approximately 4 million units) <Delivery Performance of Special Shaped Wire (Coils and Bars)> For automotive parts, submarine cables, various nuts, grating, collector rails, non-ferrous terminals, thermal power plant boilers, etc. 2024 performance (monthly production of approximately 600 tons) <Other Wire Products> Steel wire for cold forming (CHQ wire), steel wire, iron wire. 2024 performance (monthly production of approximately 500 tons) *Automotive-related sales ratio approximately 60%

[Notice of Expo Participation] "Ultra Deformed Wire" Exhibition!

  • COMPANY

We are pleased to announce that our company will be exhibiting at the "MOBIO Osaka Pavilion Exhibition: 'No/BORdER - A Technology Exhibition that Transcends Borders, Barriers, Times, and Walls'" to be held at the "Reborn Challenge" area of the Osaka Healthcare Pavilion during the 2025 Osaka-Kansai Expo. ■Overview Exhibition Dates: July 8 (Tuesday) to July 14 (Monday), 2025 Hours: 9:00 AM to 9:00 PM Location: 2025 Osaka-Kansai Expo, Osaka Healthcare Pavilion "Reborn Challenge" area *No reservation required https://beyond-borders-expo-m-osaka.jp/ ■Exhibition Content We will showcase our unique processed material, the copper special-shaped wire "Ultra Deformed Wire (UDW)." UDW is a revolutionary material that allows for the design of varying thicknesses and widths within a single wire. It serves as an alternative to motor magnet wire, enabling the development of high-output, compact motors and contributing to carbon neutrality through improved energy efficiency. This next-generation technology is expected to be utilized in various fields, including mobility and robotics, truly "transcending walls." We invite you to visit our booth at the expo, where future technologies will gather.

[Featured Product] "New Development and Contract Manufacturing of Copper Products for EVs" / Namitei Co., Ltd.

  • PRODUCT

Utilizing irregularly shaped wires, we manufacture a wide variety of plate thicknesses and cross-sectional shapes. We are capable of mass-producing high-capacity copper components for mounting. Our company is engaged in the development and manufacturing of "copper products for EVs" using irregular cross-section busbar materials and press-processed mounting components made from irregular wires. We can vary the thickness and side shapes, allowing for highly flexible designs such as undulating shapes, asymmetrical shapes, and hollowing, accommodating processing tailored to customer needs. In addition to providing long coils suitable for continuous production, we can also manufacture terminals, iron cores, contact pieces, and contacts for high-capacity circuit breakers. 【Examples of Developed Products】 ■ Busbar materials for bending ■ Copper components for mounting ■ EV relay-related components *For more details, please refer to the introduction materials available for download in PDF format. Feel free to contact us with any inquiries.
