Custom Magnets & Magnetic Assemblies Manufacturer

JDM supports B2B projects with end-to-end capability: material selection → sintering/bonding → precision machining → coating → magnetization → assembly & inspection.

Send your drawing (STEP/DWG/PDF) and working conditions. We’ll recommend the right material, coating, and magnetization direction for your application.

Materials: NdFeB / SmCo / Ferrite / Bonded Finishes: Ni-Cu-Ni / Zn / Epoxy / Gold (on request) Magnetization: axial / diametral / radial / multipole Inspection: flux mapping / pull force / coating thickness & adhesion

FAQ

Which magnet material should I choose?
NdFeB for highest strength, SmCo for high temperature & stability, Ferrite for cost-effective corrosion resistance, Bonded for complex shapes and tight tolerances.
What information do you need for a fast quote?
Drawing (STEP/DWG/PDF) + tolerance, working conditions (temperature/corrosion), target performance (pull force/flux), quantity and delivery schedule.
Can you support custom magnetization?
Yes—axial, diametral, radial and multipole magnetization are available depending on geometry and fixture feasibility.
How do you ensure coating quality?
We can inspect coating thickness and adhesion, and recommend Ni-Cu-Ni / Zn / Epoxy based on corrosion level and application risks.
