SUPPLY CHAIN
Non-Chinese Supply Chain
The use of rare earth metals is a major factor in determining the cost of magnets and magnetic assemblies. Rare earth materials are mined in a few places around the world. Today 60% of the rare earth elements are mined in China. China manufactures over 80% of the world’s neodymium magnets. The U.S. and China relationship can be summed up as volatile. For its part, Bunting-Dubois continues to seek alternative sources for neodymium, reducing the reliance on China for the commodity.
- Manufactured In the U.S.A.
- International Traffic in Arms Regulations Registered

Finite Element Analysis
Finite Element Analysis (FEA) modeling programs are used to analyze magnetic problems in order to arrive at solutions, which can then be tested and fine tuned against a prototype of the magnet structure. Using FEA models flux densities, torques, and forces may be calculated. Results can be output in various forms, including plots of vector magnetic potentials, flux density maps, and flux pattern plots. The Design Engineering team at Bunting has extensive experience in many types of magnetic designs and is able to assist in the design and execution of FEA models.
Rapid Prototyping for Development
We collaborate with your team to create well-designed, flawlessly manufactured permanent magnets and magnetic assemblies specific to the unique needs of your application. We are able to provide rapid prototypes and quick distribution of the final product no matter the complexity. When working with our engineers, you are involved with the design process from start to finish. We have an on-site prototyping facility and our engineers are backed by our world-class manufacturing team, delivering you a product in TWO WEEKS OR LESS. We provide as much application engineering as needed, and allow you to receive more than one prototype at a time if you are configuring multiple designs.
3-D Printing Capabilities
Bunting offers 3D printing, enabling our engineers to efficiently create product prototypes, ultimately saving time and money.
Fast Distribution
Our location in Pennsylvania means our North American customers receive their goods quicker and at lower freight costs. We can work seamlessly with your lean replenishment programs, employing JIT, Kanban, Dock-to-Stock, etc, to ensure your magnets are available when you need them. While our assortment of equipment and a highly experienced team means you get the product you need for any application, our US location promises fast shipping and lower freight costs from our North American customers.
