By applying our core technology of shaped wire drawing to non-ferrous materials, we can achieve high functionality in electronic components. The "high capacity" of EVs and "lightweighting" through the replacement with aluminum parts, along with the use of shaped wires that closely match the component shapes, enable the production of non-ferrous parts with high yield. You can view materials introducing examples of processing shaped metal parts such as heat sinks, EV relays, busbars, and shafts by downloading the PDF.

Our company specializes in the production of "shaped wire" by processing coil materials through wire drawing and rolling to achieve the desired cross-sectional shape. In addition to enabling lightweight wire and providing anti-slip performance, we can reduce subsequent processes such as cutting and forging, leading to improved yield and reduced processing costs. We also manufacture functional wire materials such as hollow shaped wire and perform shaped cutting with minimal burrs and sagging. 【Features】 ■ Reduces costs in subsequent processes with shapes close to the final product ■ Accommodates various shapes including uneven surfaces, curves, and asymmetrical types ■ Suitable processing for multiple fields such as construction materials, automotive, civil engineering, and home appliances ■ Supports delivery forms such as aligned winding, carrier removal, and bar bundling *For more details, please refer to the materials available for download in PDF format. Feel free to contact us with any inquiries.

Our company is committed to "modern manufacturing," starting with the production of nails and evolving through various transformations, including the production of copper shaped wires, growing alongside the times. We manufacture a variety of shaped wires with different cross-sectional shapes, as well as related components. Based on the manufacturing technology of shaped wires that we have cultivated over many years, we cater to a wide range of needs, from everyday life-related fields such as automotive, construction, civil engineering, home appliances, and plants, to global and cutting-edge areas like submarine cables.

Namitei specializes in the production of shaped coil wire using coil wire materials, and has produced a large number of shaped wires for automotive parts as well as for plants and civil engineering. Recently, in the automotive industry, "weight reduction" has become an important improvement theme as the industry moves towards electrification due to environmental issues. In this context, our company is working on the development of hollow shaped wires using pipe coil materials. Although the material costs increase by switching to pipe coil materials, the weight reduction offsets this increase, resulting in cases where we have successfully achieved weight reduction at nearly the same price depending on the specifications. Additionally, beyond weight reduction, products have also been commercialized using shaped core materials for lance (cutting rods).

At Namitei, while leveraging the applications and functions of our products, we propose product specifications that match our processing characteristics, aiming for cost-effective manufacturing. Please feel free to consult us from the design stage. We are a wire product manufacturer and conduct integrated production up to the component level. In applications such as heat exchange pipes using hollow shaped drawn wire, we propose new parts materials for pipe-in-pipe applications. *For more details, please refer to the PDF materials or feel free to contact us.

"Shape forging" offers cost advantages by approximating the final shape of parts at the material stage, allowing for the omission and simplification of cutting and forging processes, as well as improving yield. Additionally, compared to other methods, it enhances strength by utilizing toughness and improves quality in terms of precision and surface characteristics. While there are constraints on the freedom of shape due to processing characteristics, we will propose specifications according to the application and function. [Advantages of Shape Forging] ■ Omission and labor-saving of the pressing process ■ Improved yield ■ Increased strength *For more details, please refer to the PDF materials or feel free to contact us.

Our unique shear technology allows for the continuous and high-precision cutting of irregular coils. The proprietary method "Fine Cut" offers excellent flatness of the cut surface, with minimal occurrence of burrs and deformation, enabling some cases to be used directly as components. 【Capabilities of Fine Cut】 ◆ Process Simplification Due to the excellent flatness of the cut surface, it is possible to omit or reduce subsequent processing (such as barreling and machining). ◆ Continuous Production High mass production capability is achieved by continuously cutting from coils. ◆ Dimensional Accuracy - Minimal deformation leads to high length accuracy. - High length accuracy ensures stable weight per piece. *Examples of use: Slag, weights, etc. ◆ Method Switching Enables the switching of sintered parts, pressed parts, and former parts to Fine Cut. *Sintered alternative parts, pressed alternative parts. ◆ Environmental Consideration By achieving simplification and labor-saving through process omission, continuous production, and method switching, we can engage in environmentally friendly manufacturing.

This is a unique solution that uses cold forging technology with irregularly shaped materials to create complex shapes with high precision. It is compatible with both iron-based and copper-based materials, enabling a transition from pressing and cutting methods. There are achievements in a wide range of industries, from automotive parts to construction and building materials. 【Capabilities of Irregularly Shaped Forged Parts】 - Achieves near-net shape, reducing machining and labor costs (cutting-free parts) - Realizes shapes that are difficult to produce with pressing (press alternative parts) - High strength and durability through plastic processing * Parts with greater strength than those produced by sintering can be manufactured (sintering alternative parts) - Simultaneously achieves cost reduction and quality stabilization through method changes.

By using "near-net shape" irregular coils that are pre-processed into shapes close to the final product, rather than using general materials like circles, squares, or hexagons, production can be carried out continuously. This enables a reduction in processing steps and allows for labor-saving and efficiency improvements, leading to a more efficient and smarter way of working.

Since the 2000s, we have established a track record in mass production technology and quality control in the field of terminals for EV relays. We offer two types of manufacturing methods: (1) A combination of cold forging and machining (2) Cold forging only (without machining) We can propose optimal process designs tailored to shape, quality, and quantity. Leveraging our experience with EV relay terminals, we believe we can also expand into the following industrial equipment and energy sectors. ◆ Proposal Examples 【Industrial Equipment and Infrastructure】 High-power motor control for machine tools, injection molding machines, and presses, as well as UPS and DC power supply systems. 【Renewable Energy】 DC cut relays for solar power generation systems and power conversion units for wind power generation. 【Power Supply Infrastructure】 Distribution boards and backup power for data centers, battery energy storage systems (BESS). We believe that the know-how we have gained from manufacturing terminals that withstand "high voltage and high current environments" required in the EV market can also be utilized in the industrial and energy infrastructure sectors.
