ナミテイ Company Overview

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%

New press parts that "create shapes from materials" instead of processing【Utilization of irregular wire】

New press parts that "create shapes from materials" instead of processing【Utilization of irregular wire】

Forming difficult thicknesses, grooves, and complex R shapes at the material stage, which are challenging in pressing. Achieving reduced processes, material loss, and labor savings while enhancing design flexibility.

By utilizing irregularly shaped wire, we can make parts that were difficult to achieve with conventional press processing possible. With a high degree of freedom in shape, we can provide optimal proposals tailored to our customers' needs from the design stage. 【Examples of processing made possible by our technology】 - Thickness and shape: High design freedom in cross-sectional shape allows for lightweight parts and strength optimization. - Grooves and uneven shapes: Uniform and high-precision grooves or complex three-dimensional shapes can be formed in one piece. - Composite R shapes: Smooth curves and continuous complex curvatures can be easily accommodated. - Notched shapes: Notches can also be accommodated without cutting. Additionally, new press parts enable waste-free production by pursuing manufacturing efficiency from the design stage. Specifically, the following effects can be expected: 【Environmentally friendly and efficient manufacturing process】 1. Shortening of manufacturing processes 2. Reduction of material waste 3. Reduction of labor and effort 4. Minimization of energy consumption ◆◆ Development story of irregularly shaped wire for submarine cable fiber optic protection ◆◆ https://www.namitei.co.jp/products/submarinecable/#story

[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.
