Custom Assemblies — Your Design, Our Manufacturing

If it involves magnets and other components — we build it. Send a drawing or just a concept; we'll engineer the assembly, manufacture the components, integrate them, and test the finished part.

One Part Number Instead of Ten

Every component you add to your BOM adds receiving, inspection, inventory, and assembly cost. We consolidate.

  • Single-source accountability — one supplier responsible for the complete assembly — no finger-pointing between magnet, machining, and molding vendors
  • Integrated design review — we optimize across materials and processes — sometimes a molding change eliminates a machining operation entirely
  • Functional testing on the finished part — torque, flux, pull force, electrical continuity — tested as an assembly, not just as components
  • Kit packaging available — assemblies packaged for direct-to-line delivery — labeled, barcoded, and sequenced to your production schedule

How to Start

Three ways to bring us your project:

  • Complete drawing package — fastest path — we quote the assembly as-is and flag DFM issues early in the process
  • Performance specification — tell us what the assembly must do (force, torque, field) and the space envelope — we design and quote
  • Concept or problem statement — describe the function you need — our engineers propose 2–3 design approaches with trade-offs before quoting

Quality Documentation

Custom assemblies ship with documentation appropriate to your industry:

  • Standard — inspection report with dimensional and functional test data per shipment
  • Automotive (IATF) — PPAP documentation per project requirements, process capability studies, control plan, MSA
  • Medical & regulated — device master record support, process validation (IQ/OQ/PQ), lot traceability
Production & Supply Planning

Custom Magnetic Assemblies: A Defined Route to Repeat Orders

Agree the process, acceptance criteria and shipment plan before production starts. The quotation identifies the producing site and the controls required for your part.

  1. Confirm the manufacturing route

    Review magnetic parts, machined interfaces, adhesives or mechanical retention, and assembly sequence together.

  2. Approve the inspection plan

    Define magnetic or functional tests, interface dimensions and mechanical retention acceptance.

  3. Qualify before repeat supply

    Define sample approval, drawing revision and lot identification. Agree how material, process or site changes will be reviewed before implementation.

  4. Plan releases and delivery

    Confirm order quantities, capacity allocation, packaging and shipping terms against your forecast. Delivery dates and any buffer-stock arrangement belong in the agreed supply plan.

Application Engineering

Where custom magnetic assemblies Fit

Typical component uses and the requirements to discuss before quotation. Suitability depends on your design and validation criteria.

Automotive magnetic systems

Operating temperature, vibration, retention and field requirements.

Industrial automation assemblies

Force or torque targets, air gap and mounting interfaces.

Medical equipment assemblies

Magnetic performance, cleanability and equipment-specific qualification.

Energy and power systems

Duty cycle, environment and magnetic circuit design.

Frequently Asked Questions

What's the minimum order for a custom assembly?

Prototypes start at 1 piece. Production assemblies vary: bonded assemblies from 100 pieces; insert-molded assemblies from 5,000 pieces (tooling amortized); machined assemblies from 10 pieces. Tell us your annual volume — we'll find the most cost-effective process.

Can you work from just a concept?

Yes — describe the function you need (holding force, torque, field strength, geometry constraints) and we'll propose a design. Our engineering team does this weekly. There's no charge for initial design proposals on projects with realistic production volume.

How do you handle intellectual property?

We sign NDAs before receiving confidential drawings, and all tooling we build for your parts is your property. We do not manufacture proprietary assemblies for your competitors — exclusivity agreements available on request.

Can you manage sub-suppliers for components you don't make?

Yes — we regularly integrate customer-specified components (bearings, sensors, fasteners) and manage qualified sub-suppliers for specialized processes (plating, heat treatment). You receive a single assembly with one warranty.

Validation & Testing of Your Assembly

Magnetic Verification

Flux density, pole pattern and magnetization verified per the agreed plan — hall-probe mapping, Helmholtz coil measurements, or functional pull tests.

Mechanical Verification

Bond strength, concentricity and dynamic balance validated for rotating parts; dimensional reports on critical interfaces.

Documentation

Inspection plans, FAI and PPAP per project requirements; every assembly ships with the agreed test evidence as one part number.

Have an Assembly Drawing or BOM?

Send it to our team — we'll review the design and quote it as a validated, ready-to-install assembly.
