Neodymium Iron Boron (Neodymium) magnets are the most common rare earth permanent magnets in the world. They are known for being the strongest magnetic material available, and can be used in a diverse range of applications. At Bunting-DuBois, our unique manufacturing and design capabilities allow us to take the power of neo magnets to the next level. We can produce custom designed sintered, injection molded, and compression bonded neodymium magnets according to your application requirements. For situations where a basic in-stock neodymium magnet will not meet your needs, we offer complete design and manufacture solutions.
When utilizing neodymium magnets, their raw power is only one part of the equation. There are many factors surrounding the use of neo magnets in various designs, and the design team at Bunting-DuBois uses Finite Element Analysis (FEA) modeling programs to analyze specific magnetic problems and deliver targeted solutions. Designing an optimum magnet typically requires some tradeoffs, but at Bunting, we have the expertise to minimize tradeoffs and maximize performance when designing a custom neodymium magnet for your application.
Neodymium magnets, like other rare-earth magnets, often require specific manufacturing conditions. For example, certain rare-earth magnets require extremely high magnetizing fields that are difficult to produce and demand large power supplies, as well as very carefully designed magnetizing fixtures. Bunting’s advanced design and production facilities allow us to offer magnets and magnetizing solutions that require these high magnetizing fields, even in the case of isotropic bonded neodymium materials that demand up to 60 kOe to reach full saturation.
Multi-Pole Magnetization for Neo Magnets
Bunting is able to provide multi-pole magnetization as one of our many design services. Many customers seek to magnetize a part with multi-pole configurations. It requires a great deal of design expertise to successfully magnetize multi-pole rare-earth magnets, and these fixtures can be complex. However, multi-pole magnetization is still extremely sought after for use in a variety of applications. While it is challenging to design and manufacture multi-pole rare-earth magnets, Bunting engineers have the experience and knowledge necessary to accomplish this design task.
Custom Designed Neodymium Magnets from Bunting
While many vendors offer standard in-stock neodymium magnets, Bunting offers several unique varieties that are difficult to find elsewhere. If you are seeking an engineered neodymium magnet, we have an enormous range of custom design options, with many shapes, sizes, strengths, and coatings available. We also offer bonded neodymium magnets that may be compression bonded or injection molded to achieve your desired shape. Bonded neodymium magnets boast high performance, high tolerances, low electrical conductivity, and a low price point, making them a cost-effective option. Bonded neodymium magnets can be manufactured in complex shapes and require no coating, although black epoxy and Parylene coatings are available.
Injection Molded Neodymium Magnets
Injection molded neodymium magnets are one of Bunting’s specialties. Our ability to produce injection molded magnets allows us to create magnets in complex shapes with high levels of precision, as well as insert or over-molding. Injection molding allows us to create many identical magnetic components in a short amount of time, making this method ideal for high-volume production. Injection molding not only delivers high volume output and productivity, but also provides magnets with tight tolerances that would be unachievable otherwise. For complex, high-volume applications, our injection molding capabilities are a time-saving, cost-efficient option to pursue.
Total Magnetic Solutions
At Bunting, we provide total magnetic solutions. All of our custom designed magnets and magnet applications have the option for rapid prototyping, and our engineers work with you at every step of the process to deliver a custom designed solution that meets the exact needs of your application. We can manufacture magnets and magnetic assemblies in any quantity, and our unique injection molding capabilities make us well suited for high-volume applications.
