Custom Halbach Assemblies

Buyer Decision Criteria

• Target 3D field shape and the volume where that field matters.
• Mechanical envelope, mounting interfaces, and prohibited materials.
• Operating temperature, duty cycle, vibration, vacuum, or chemical exposure.
• Prototype acceptance criteria and production quantity roadmap.

Factory Capability

• Early DFM review of simulated magnetic layouts before tooling.
• Custom non-magnetic fixtures for safe assembly of unusual magnetic forces.
• NdFeB, SmCo, coatings, sleeves, potting, and carrier choices by environment.
• Prototype-to-production control plan for repeatable custom assemblies.

RFQ Checklist

1. Target 3D field map
2. Spatial constraints
3. Environmental conditions
4. CAD, forbidden materials, acceptance method, quantity ramp, and delivery country

Risk Controls

• Unmanufacturable designs: Early DFM review to ensure the simulated array can be physically assembled safely.
• Prototype disagreement because acceptance was not defined: Set magnetic, dimensional, and documentation deliverables before sample production.
• Hidden assembly-force hazards: Review magnetized assembly path and non-magnetic fixture needs during DFM.

Validation Deliverables

• RFQ feasibility notes and open-issue list.
• Field map or inspection method matched to the target magnetic function.
• Critical dimension and assembly process confirmation.
• Revision-controlled quote scope for engineering changes.

RFQ to Delivery Flow

1. Send CAD, target field map, tolerance priorities, environment, quantity, and timing.
2. We return feasibility, missing inputs, and manufacturability risks before formal quote freeze.
3. Prototype scope locks the validation method before production planning.
4. Mass production uses the approved fixture, material, inspection, and packaging plan.
