- To protect the magnet from corrosion and to strengthen the magnet material, it is usually preferable for the magnet to be coated. There are a number of options for coatings, but nickel is the most common and preferred. Neodymium magnets are part of the Rare Earth magnet family and are the most powerful permanent magnets.

To Build The Best Products, Some Assemblies Required.
Bunting-DuBois offers customers turnkey solutions for magnetic assemblies, each designed and built around our core magnets. With all of our projects – from a two-piece assembly to a complex product that demands precision design – Bunting-DuBois strives to meet your exact requirements and complete projects that will reduce cost drivers and develop a repeatable manufacturing process. Plus, we can work with you on your lean manufacturing replenishment program (JIT, Kanban, Dock-to-Stock, etc.) to ensure your parts are always available when you need them.
Bunting-DuBois can design the assembly, source the magnetic material, integrate the manufacture of the magnet and assembly, coat it, glue it, magnetize it, package it and ship it, all on time and within budget. Our interdisciplinary capabilities make Bunting-DuBois the ideal choice for the design, engineering, prototyping and manufacturing of magnetic assemblies – right here in the United States.
Bunting’s wide range of equipment features magnetic separation products, metal detection devices, material handling conveyors, printing cylinders, custom magnets and magnetic assemblies, in-stock neodymium magnets, and more. All of our equipment is designed to be low-maintenance and operator friendly to increase efficiency and decrease.

Considerations for Engineering Magnetic Assemblies
Bunting-DuBois engineers take the following into consideration with every project to ensure the assembly meets your expectations for safety, quality and usability.
Affixing Magnets to Housings
Magnets can be successfully affixed to housings using adhesives. Some adhesives are rated to temperatures up to 180°C with fast cure times. Adhesives with higher temperature ratings are also available, but these require oven curing and fixturing of the magnets to hold them in a vacuum which takes more assembly time. Potential outgassing of the adhesives is considered.
Mechanical Fastening
When multiple magnets are assembled, especially when the magnets are placed in repelling positions, we carefully consider safety issues. Modern magnet materials such as Neodymium are extremely powerful, and when in repulsion they can behave as projectiles if adhesives were to break down. In these situations, we include mechanical fastening in the design in addition to adhesives. Potential methods of mechanical retention include encasement, pinning, or strapping the magnets in place with non-magnetic metal components.
Potting
Magnet assemblies may be potted to fill gaps or to cover entire arrays of magnets. Potting compounds cure to hard and durable finishes and are available to resist a variety of environments, such as elevated temperatures, water flow, etc. When cured, the potting compounds may be machined to provide accurate finished parts.
Welding
Assemblies which are required to be hermetically sealed are welded using either laser welding (which is not affected by the presence of magnetic fields) or TIG welding (using appropriate shunting elements to reduce the effect of magnetic fields on the weld arc). Special care should be taken when welding magnetic assemblies so that heat dissipation of the weld does not affect the magnets.

Bunting: Global. Magnetic. Force.
Who Are We?
Bunting began in 1959 as Bunting Magnetics Co., a small company in Chicago that gradually grew into a worldwide designer, supplier, and manufacturer of cutting-edge magnetic technology. With multiple locations in the United States as well as overseas, Bunting is entirely focused on providing total magnetic solutions in the form of custom magnets and magnetic assemblies for industries including the automotive, medical, consumer electronic, and aerospace industries, as well as serving unique military, industrial, and commercial applications.
Rebranding:
You may have known us before under the name “Magnet Applications.” In celebration of Bunting’s 60th anniversary, all branches of the company were united under the new name “Bunting” as part of a rebranding campaign. The decision to rebrand was made with the goal of uniting all companies associated with the Bunting brand under one name, eliminating confusion for customers and establishing the Bunting brand as a world force. We hope that when people hear the name Bunting, they will immediately think of the company dedicated to providing the best customer service and highest quality magnets, magnetic assemblies, and magnetic equipment in the industry.
The Bunting family has owned and operated Bunting since it was founded in 1959 by Walter and June Bunting. The stability for this 60-year old family-owned business was celebrated on August 3, 2019 with a new look and logo. The company spans three generations of the Bunting family with a fourth generation waiting in the wings!
Bunting-DuBois undertakes a wide range of design contracts and our expertise covers the complete range of permanent magnet materials, including; alnico, ferrite, samarium cobalt, neodymium iron boron, through numerous production routes, including sintering, extrusion, calendaring, compression bonding and injection molding.
Our ability to build magnetizing fixtures, manufacture magnets, and supply machined components from our in house facilities offers a rapid prototype service.
We’re capable of running both ferrite and rare earth compounds. Our single part production rates range from a few hundred pieces per month to more than 2 million pieces per month.
