ナミテイ Product Lineup

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.

"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.

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.

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 utilizing irregularly shaped wire, we can make parts that were difficult to achieve with conventional press processing possible. With high design flexibility, we provide optimal proposals tailored to our customers' needs from the design stage. 【Examples of processing made possible by our technology】 1. Groove processing: Stable formation of uniform and high-precision grooves. 2. Uneven surface processing: Capable of handling complex three-dimensional shapes in a single formation. 3. Compound R processing and round R processing: Freely accommodating gentle curves and complex curvatures continuously. 4. Free design of thickness and width shapes: High design flexibility for cross-sectional shapes enables lightweighting and strength optimization of parts. 5. Compatibility with difficult materials: Capable of processing high-hardness materials and special steels that are considered challenging. 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.

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.

We manufacture various components and parts used in electromagnetic devices using electromagnetic soft iron and deformed wire and wire materials made of copper and copper alloys. We achieve optimal shapes for applications that require electrical and magnetic characteristics, such as busbars, core materials, large terminals, and terminals. **Benefits of Using Deformed Wire** - **Minimization of Material Loss** By shaping the wire material into a cross-section close to the desired shape, we achieve higher yield compared to pressing and cutting from sheet materials, significantly reducing material usage. - **Excellent Electrical and Magnetic Properties** By processing electromagnetic soft iron and high-conductivity copper alloys directly as wire materials, we can design low-loss, high-efficiency components that take advantage of the crystal structure. - **Cost Reduction through Process Conversion** By replacing multiple processes such as cutting, stacking, and brazing with bending, forging, and cold forming of wire materials, we contribute to process shortening and quality stabilization. **Deformed Wire UDW (Ultra Deformed Wire) with Variable Thickness and Width in the Longitudinal Direction** Winding this new deformed wire, which changes shape, increases the copper occupancy rate in motors, leading to the development of more efficient motors.
