Magnetic assemblies combine permanent magnets with precision-machined components — housings, poles, yokes, shafts, or brackets — to deliver optimized magnetic performance for a specific application. Assemblies allow designers to concentrate and direct magnetic flux, protect the magnet from mechanical stress and corrosion, and simplify installation into larger systems. Common magnetic assembly types include pot magnets, magnetic chucks, rotor assemblies, sensor targets, holding assemblies, and custom engineered configurations for motors, actuators, and medical devices.

What to Look for in a Magnetic Assembly Supplier

• Design and engineering capability — The best assembly suppliers bring magnetic design expertise to the project, not just manufacturing. Look for suppliers who can model flux paths, recommend magnet grades, and optimize geometry for your performance requirements.
• Machining and tolerance control — Precision assemblies require tight dimensional tolerances on both the magnet and surrounding components. Ask about in-house machining capabilities and inspection equipment.
• Material compatibility — Assemblies combine magnets with steel, aluminum, stainless, or engineered plastics. Confirm the supplier understands how material choices affect magnetic circuit performance and corrosion resistance.
• Magnetizing after assembly — Some assembly designs require magnetizing after the components are assembled. Confirm the supplier has appropriate magnetizing fixtures and field strength capabilities for your configuration.
• Testing and validation — Finished assemblies should be tested for pull force, flux density, or other performance parameters before shipment. Ask what testing is performed as part of the standard production process.
