ナミテイ Product Lineup

Our company has been producing copper terminal components for EVs for over 10 years, and we have established a quality assurance system that includes a production system utilizing cold forging formers and machining, as well as complete inspection, cleaning, and vacuum packaging. Furthermore, we can also manufacture irregular terminals using our specialty in irregular wire, allowing us to broadly meet the increasing demand for copper terminals and components due to the rise of EVs. 【Features】 ■ Over 10 years of manufacturing know-how for iron cores and contacts ■ Introduction of high-performance cold forging formers ■ Realization of machining-free copper terminal components ■ Cost-effective solutions available ■ High-quality assurance system in place due to vacuum packaging ■ Capability to manufacture irregular shapes

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.

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.

Our company is engaged in the development and manufacturing of "copper products for EVs" utilizing our manufacturing technology for shaped wire, including busbar materials with irregular cross-sections and press-processed components for mounting. We can vary the thickness and side shapes, allowing for highly flexible designs such as undulating shapes, asymmetrical shapes, and hollowing, enabling us to accommodate processing tailored to customer needs. We also provide long coils suitable for continuous production, as well as the manufacturing of 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.

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.

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.
