"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.

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.

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.

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.

The "Irregular Magnet Wire" handled by Namitei Co., Ltd. is a wire that can be used for new motor designs with the desired cross-sectional shape. Additionally, we also handle "Ultra Deformed Wire," which can be utilized for increasing the packing density of motor coils and for miniaturization. We will consider the introduction of mass production equipment based on the type of insulation coating, coating method, and production volume. Please provide the insulation conditions, including types such as PAI and PEEK. 【Winding Processing (Ultra Deformed Wire)】 ■ Prototype Support: Available depending on specifications ■ Mass Production Support: In-house production is considered for small to medium lots, while large lots will be discussed separately through negotiations ■ Winding Equipment: We can introduce equipment manufacturers as needed *For more details, please download the PDF or feel free to contact us.

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.

We would like to introduce the "Precision Parts" that we handle. By using deformed wire that closely resembles the shape of the parts, we can reduce scrap, and there is no need for large press molds to bend or cut the wire. Mass production is possible in the finishing process, such as cutting, using deformed wire as the material. Copper strips are made from single-layer materials, but since the wire is long, continuous production efficiency is improved. 【Specifications】 ■Material: Copper, Aluminum, Iron ■Dimensions ・Thickness: 1.0 to 5.0 mm ・Width: 5.0 to 25.0 mm *For more details, please download the PDF or feel free to contact us.
