Magnetic Assemblies Built for Integration — Not Just Individual Magnets.
Rotor assemblies, Halbach arrays, overmolded magnets, magnetic couplings and custom assemblies engineered to your interface and performance requirements.
Magnetic Rotor Assemblies
Magnet + shaft + steel core assemblies for motors, pumps, and compressors. Balanced and ready to install.
View capabilities →
Halbach Arrays
One-sided flux concentration arrays for brushless motors, magnetic levitation, and analytical instruments.
View capabilities →
Overmolded Magnets
Magnets encapsulated in nylon, PPO, or PPS via insert molding — for seals, rotors, and hygiene-critical parts.
View capabilities →
Magnetic Couplings
Hermetically sealed torque transfer through containment cans — zero leakage pumps and agitators.
View capabilities →
Custom Assemblies
Your design, our manufacturing: magnet + metal + plastic + sensor integration under a group quality framework.

Fewer Parts to Manage
One part number instead of five. One supplier, one shipment, one quality framework. Your receiving and assembly operations get simpler and cheaper.
Tighter Performance Control
We control the magnet grade, the steel composition, and the air gap — and verify the assembled performance, not just the components.
Assembly-Level Testing
Every assembly ships with functional test data: torque, flux, pull force, or back-EMF — measured on the finished part, not inferred from components.
Our Assembly Capabilities
Magnet Bonding
Structural epoxies and anaerobic adhesives, shear-tested per lot.
Insert Molding
Nylon, PPO, PPS overmolding on magnet and metal inserts.
Machining
Turning, milling, and grinding of assembly components post-bond.
Dynamic Balancing
Rotor balancing to G2.5 or tighter per ISO 21940.
Magnetization
Multi-pole, skew, and pattern magnetization of finished assemblies.
Sensor Integration
Hall-effect and encoder integration into magnet assemblies.
Potting & Sealing
Epoxy potting for IP67 sealing in harsh environments.
Cleanroom Packing
Clean packing for medical and food-grade applications.
What to Include in Your RFQ
Assembly-level detail helps us quote a finished, tested part — not just components.
Assembly Definition
- ✓Assembly drawing or BOM with exploded view
- ✓Interface dimensions — shaft diameter, bore tolerance, air gap
- ✓Material specifications for each component
Performance Targets
- ✓Required output — torque, flux density, pull force, back-EMF
- ✓Operating speed, temperature range, sealing requirement
- ✓Applicable standards — ISO, IEC, or automotive (IATF 16949)
Production & Quality
- ✓Annual volume and ramp-up schedule
- ✓Inspection plan — what to test on the finished assembly
- ✓Packaging and labeling requirements
Owned Magnetic Assembly Operations
Magnet and assembly requirements are reviewed together, including mechanical interfaces, retention, working gap and the measurement method for the finished assembly.
