Common Applications for Our Magnetic Assemblies

Considerations for Engineering Magnetic Assemblies

Magnet Applications, Inc. 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.
