Capabilities

OEM Capabilities

Factory-side engineering and supply capability designed for custom bonded magnet projects, from DFM and tooling to sample validation and repeat production.

This section is organized around the buyer journey: requirement closure, tooling NRE, insert retention, magnetization evidence, process quality, and production transfer.

OEM Program Control Flow

  1. Freeze drawing, material, insert, and magnetic pattern inputs.
  2. Review DFM, tooling, and magnetization fixture feasibility.
  3. Execute sample plan with dimensional, magnetic, and retention acceptance criteria.
  4. Map CTQ characteristics to process checkpoints and records.

Custom Magnet Tooling and NRE

DFM, mold design, sample tooling, and NRE planning for custom injection molded magnet programs.

Best for OEM teams that need a custom magnet part rather than an off-the-shelf catalog magnet.

  • Tooling review before prototype and production release
  • Molded geometry, insert, gate, and magnetization plan considered together
  • NRE planning for automotive and industrial OEM projects

Insert molded magnet overmolded on shaft

Insert Molding and Magnet Overmolding

Overmold bonded magnet material onto shafts, hubs, bushings, and carriers to reduce adhesive assembly and alignment risk.

Best for buyers replacing glued magnet assemblies or adding magnetic function to an existing mechanical part.

  • Steel shaft, brass insert, plastic carrier, and custom hub overmolding
  • Mechanical retention reviewed with magnetic datum control
  • BOM and assembly step reduction for sensor and motor rotors

Multi-Pole Magnetization

Magnetization planning for multi-pole rings, sensor rotors, encoded magnets, and custom magnetic field profiles.

Best for engineering teams where magnetic field shape is the product function, not just a material property.

  • Radial, diametrical, axial, and multi-pole pattern review
  • Fixture and inspection approach tied to the final sensor or motor function
  • Magnetic acceptance criteria defined before sample release

Automotive Quality and PPAP Support

Quality documentation orientation for automotive bonded magnet projects, from CTQ definition to sample inspection evidence.

Best for automotive sourcing teams that need more than a prototype magnet and require release evidence.

  • IATF-style quality thinking for custom magnetic components
  • CTQ review across molded dimensions, inserts, and magnetic output
  • Documentation support for sample approval and production transfer

CapabilityPrimary Buyer FocusKey MetricWhy It Matters
Custom Magnet Tooling and NREBest for OEM teams that need a custom magnet part rather than an off-the-shelf catalog magnet.Tooling release package: Drawing, material, magnetization, inspection, and sample planInjection molded magnets are tooling-led projects; unclear inputs create costly revision loops.
Insert Molding and Magnet OvermoldingBest for buyers replacing glued magnet assemblies or adding magnetic function to an existing mechanical part.Retention force: Defined by pull-out, push-out, or torsion requirementA sensor rotor can pass magnetic testing but still fail if the insert interface moves under load.
Multi-Pole MagnetizationBest for engineering teams where magnetic field shape is the product function, not just a material property.Pole-to-datum alignment: Project-defined reference angle or mechanical keyAssembly teams need the magnetic pattern aligned with a physical datum to avoid calibration drift.
Automotive Quality and PPAP SupportBest for automotive sourcing teams that need more than a prototype magnet and require release evidence.CTQ coverage: Dimensions, magnetics, material, insert retention, visual releaseAutomotive buyers need measurable release criteria, not just supplier claims about quality.
