Development, prototyping, and mass production of edgewise coils.

Development, prototyping, and mass production of edgewise coils.

There are benefits such as compactness, securing cross-sectional area, and reducing heat generation and performance advantages!

Our company develops, prototypes, and mass-produces edgewise coils. Edgewise coils are coils that wind flat rectangular wire (copper wire) in a vertical direction. Depending on the application, we use different winding shapes such as round, square, rectangular, triangular, and racetrack shapes. Edgewise winding is highly challenging, and the availability of flat rectangular wire (copper wire) is poor and expensive, but it offers advantages such as compactness, securing cross-sectional area, and reducing heat generation and performance benefits. Our company can accommodate a wide range of wire diameters and can obtain flat wire in small lots, selecting according to the number of turns and specifications. Please feel free to contact us with your requests. 【Features】 ■ Flat wire can be wound in various ways, such as flat winding or alpha winding, depending on the application. ■ Different winding shapes are used according to the application. ■ A wide range of wire diameters is available, and flat wire can be obtained in small lots. ■ Selection is made according to the number of turns and specifications. *For more details, please download the PDF or feel free to contact us.

Proposal for Prototype to Mass Production

Proposal for Prototype to Mass Production

Even with a prototype mold, we implement mold design with mass production in mind! It is possible to start mass production in a short lead time.

The production of prototypes requires a balance of "delivery time," "precision," "cost," and "quality." Our company will propose suitable methods and processes while considering each of these balances for our customers. Additionally, please feel free to consult us not only about the press parts we prototype but also about mass production of products prototyped by other companies. When it comes to mass production, we also consider the total cost reduction of press products and will propose design changes as needed. 【Mitaka Industry's Prototype Balance】 ■ Precision: Achieving press-processed products with a precision of 1/100mm from the prototype stage ■ Cost: Addressing prototype needs while considering the overall cost from prototype to mass production ■ Delivery Time: Responding with an in-house integrated system, accommodating short delivery times starting from one week ■ Quality: Ensuring compliance with customer drawing precision requirements through reliable technology and high-performance measuring equipment *For more details, please refer to the PDF materials or feel free to contact us.

Development, prototyping, and mass production of bobbin coils.

Development, prototyping, and mass production of bobbin coils.

Due to the presence of a winding frame, it is possible to wind materials such as resin, iron, and aluminum, and use them according to different applications.

At Kitamoto Tech Co., Ltd., we handle the development, prototyping, and mass production of "bobbin coils" that are wound with lead wires (copper wires) onto bobbins. Since the winding is done directly onto the bobbin, the workability and insulation properties are good, allowing for various shapes. However, depending on the thickness of the bobbin, the electrical characteristics may deteriorate. Our company also conducts development and prototyping of winding coils, control boards, electronic circuits, and unit production. Please feel free to contact us with product image diagrams; hand-drawn sketches are also acceptable. 【Features】 ■ Winding can be done on materials such as resin, iron, and aluminum, allowing for differentiation based on application. ■ Good workability and insulation properties, enabling various shapes. ■ The applicable wire diameter ranges from φ0.012 to φ3.2 (reference value), and lead wires (copper wires) are selected according to the number of turns and specifications. *For more details, please download the PDF or feel free to contact us.

Development, prototyping, and mass production of bobbinless coils.

Development, prototyping, and mass production of bobbinless coils.

It is possible to incorporate winding coils in a minimal space! Coils with a diameter of 0.5 mm or more can also be produced.

At Kitamoto Tech Co., Ltd., we are engaged in the development, prototyping, and mass production of "bobbin coils" that use a special copper wire without a bobbin part and have a fusion layer. Since there is no bobbin, the wire is wound directly onto the winding shaft (mold), and the fusion layer on the surface of the copper wire is melted and bonded using hot air or solvents. The coil is then removed from the winding shaft after it has been solidified. Our company also conducts development and prototyping of winding coils, control boards, electronic circuits, and unit production. Please feel free to contact us with product image diagrams; hand-drawn images are also acceptable. 【Features】 ■ No bobbin allows for the incorporation of winding coils in minimal space ■ Reduction of bobbins and performance improvement ■ Using a special adhesive, we can produce wires (copper wires) without a fusion layer with a diameter of 0.5 mm or more *For more details, please download the PDF or feel free to contact us.
