Sourcing Support
- RFQ essentials: length, width, thickness, grade, magnetization direction, coating, quantity, and operating temperature.
- We review chip-risk at corners, edge handling, and packaging method before sampling.
- Hole/slot machining, polarity marking, and matched-set orientation are confirmed from drawings.
Compliance Notes
- RoHS/REACH declarations, CoA, and material trace records can be coordinated on request.
- Dimensional, magnetic, and appearance inspection reports are available for incoming QC workflows.
- Packaging labels can be aligned to lot traceability and line-side kitting requirements.
Lead Time Notes
- Lead time depends on grade, coating, tolerance, and any machining operations; confirmed after drawing review.
- Prototype and pilot batches are available subject to supplier capacity and tooling readiness.
- Expedite options can be assessed for urgent launch or replenishment windows.

Machining and tolerances for NdFeB magnets
What tolerances are realistic for NdFeB and how to avoid design rework.
FAQ
What magnetization direction should I specify?
Specify axial, diametral, or radial based on your assembly. Suppliers confirm feasibility per drawing.
What tolerances are typical?
Typical dimensional tolerance for sintered NdFeB is around +/-0.05 mm, subject to supplier confirmation.
Can you advise on coatings?
Ni-Cu-Ni is common. Zinc and epoxy are available on request. We confirm the best option with suppliers.
Can block magnets include holes or slots?
Machining features can be requested. Share drawings so suppliers can confirm feasibility.
How should I specify flatness or squareness?
Include critical tolerances in the drawing; suppliers confirm achievable flatness and squareness.
