We will propose the optimal paper bobbin design based on our extensive experience.
We will design the size and specifications according to your product requirements. Considering the usage conditions in various fields (such as clean rooms), we will propose the most suitable materials. There are various sizes available beyond those shown in the photos. Please feel free to contact us.
With an outstanding lightness of 0.57kg, it reduces transportation costs for air freight and more! Custom designs are also possible!
The "EPS Bobbin" is made from expanded polystyrene, making it much lighter compared to bobbins made from other materials, allowing it to be easily carried with one hand. Its lightweight nature helps reduce air freight costs and significantly contributes to improved work efficiency. 【Features】 ■ Excellent water resistance ■ Much lighter compared to other materials (0.57 kg for a flange diameter of 450 mm) ■ Strength, size, and winding tension can be designed according to the product. *For more details, please download the catalog or contact us.
~Evolving and Developing Bobbins~
This is a plastic pearl bobbin made from carefully selected materials for use in clean rooms. Plastic pearl refers to a lightweight plastic board with excellent compressive strength, formed by sandwiching a vacuum-formed cylindrical sheet between two sheets. By using this plastic pearl as the material, we achieve a reduction in weight while maintaining strength equivalent to that of conventional paper bobbins. Additionally, it does not emit toxic gases upon disposal, making it environmentally friendly and highly recyclable. This bobbin is well-received by customers who wish to use it in clean rooms. Sizes other than those shown in the photos are also available.
Long hole type compatible with a wide variety of winding machines! Equipped with a steel wire hook hole for easy winding operations.
The "Bobbin 445" is a bobbin with an outer diameter of φ445 mm, used for winding wires and electrical cables. <Features> - It is an integrated molding type with no gaps at the base, preventing wire from getting caught. - The hole for the winding machine's shaft is elongated, making it compatible with many winding machine manufacturers. (Compatible with shaft diameters of φ20 mm or less, within a range of 80-100 mm from the center. *Please confirm with the actual product.) - Two diagonal starting holes (5×15 mm) are installed on the body of the bobbin, making it easy to start winding the wire. 【Specifications】 ■Outer dimensions: φ445×243 mm ■Inner dimensions: φ300×193 mm ■Material: Recycled ABS ■Shipping unit: 3 ■Delivery time: 3 days ■Color: Black *For more details, please refer to the PDF document or feel free to contact us.

Some products are available for same-day shipping, so please feel free to inquire. *Custom sizes are also available. *For more details, please download the PDF or feel free to contact us.
Patent obtained for the joint development of 3D-MID technology! Meeting UL1446 requirements in the power supply field.
Alpha Japan Co., Ltd. has been manufacturing and selling PIN-type electronic device-related products (transformer bobbins, bases, etc.) since its establishment in March 1988. In 1998, we obtained UL746D certification (No. C3728) and can also meet the requirements of UL1446 (thermal classification Class B, 130°C) in the power supply field. We have conducted joint development of 3D-MID technology based on thermosetting resins with a national university-related department and obtained a patent in January 2016. Recently, we have also become capable of prototyping and are looking for partners to collaborate on commercialization. 【Business Activities】 ■ Main Operations - Development, manufacturing, and sales of thermosetting resin products and applications - Development, manufacturing, and sales of thermoplastic resin products and applications ■ Current Production Items - Bases for sensors / coil bobbins / transformer bobbins / insulating components for AV and communication devices ■ New Development Products - Development of 3D-MID substrate technology (prototyping available) *For more details, please refer to the PDF materials or feel free to contact us.
