Custom Magnetic Assemblies and Magnetic Couplings Built for Performance and Scale
We are a magnet manufacturer with strong design and development capability. Our engineering team supports magnetic circuit design, DFM, prototyping, and mass production for OEM projects, including magnetic couplings, sensor magnet modules, holding systems, and integrated magnetic components.
- Design-to-production: from concept and simulation to validated builds
- Component integration: magnets + steel parts + plastic/rubber + adhesives
- Quality system driven: stable supply, consistent performance, traceability
Faster quote: share drawing (PDF/DWG/STEP), target pull force/torque, operating temperature, coating, quantity, and application environment.
What We Build
Magnetic assemblies combine magnets with structural parts and processes to meet real-world requirements. We design and manufacture custom magnetic components for OEM products.

- Pot magnets, mounting systems, clamps, magnetic bases
- Sensor/encoder magnet modules
- Magnetic latching, holding and positioning modules
Integrated Magnetic Components
Magnet + metal + plastic/rubber integration for durability and easy assembly in the customer product.
- Overmolding / encapsulation / rubber coating
- Adhesive bonding, press-fit, fastening, welding where applicable
- Custom packaging, labeling, and kitting for your line
Magnetic Couplings: Leak-Free Torque Transmission Without Physical Contact
A magnetic coupling transfers torque through a sealed barrier using permanent magnets. It is widely used for pumps, mixers, and sealed-drive systems where leak prevention, corrosion resistance, and reduced maintenance are priorities.
Types of Magnetic Couplings We Support
- Concentric (radial) magnetic couplings for compact torque transfer
- Axial magnetic couplings for specific space constraints
- Magnetic drive assemblies for pumps and sealed mixing systems
We support custom pole design, magnet selection, and mechanical integration to match your torque and speed targets.
Engineering Focus for Better Performance
- Torque optimization: magnetic circuit and pole configuration for stable transmission
- Temperature & corrosion: choose magnet grades and coatings for harsh environments
- Misalignment tolerance: reduce vibration and improve service life
Share your target torque (Nm), RPM, air gap, operating temperature, and medium (chemical/water/oil) for fast selection.
Torque and air-gap design optimized for stable transmission and reduced leakage risk in chemical handling.
Balanced design considerations for speed, heat, and magnetic losses to improve long-term stability.
Material/coating strategy designed for humid or corrosive environments with predictable service life.
Recommended RFQ fields: torque (Nm), RPM, max temperature, medium, required air gap, outer diameter limit, shaft size, and expected duty cycle.
Design and Development Capability
Our professional design team helps you reduce risk, shorten development cycles, and improve magnetic performance. For projects like magnetic couplings, we focus on torque, air gap, and stability in production.
Magnetic Circuit Design
We optimize flux paths, air gaps, and magnet utilization to hit force/torque targets while controlling cost.
- Pull force and holding force optimization
- Field distribution and stray field control
- Tolerance stack-up and assembly repeatability
DFM + Validation
Design for manufacturability and repeatable quality, with prototypes and verification before scaling.
- Material selection: grade, coating, temperature limits
- Process selection: bonding, overmolding, fixtures
- Reliability plan: salt spray, thermal, vibration where needed
Manufacturing and Quality Control
We combine engineering discipline with stable production processes to deliver consistent magnetic components at scale.
Production Processes
- Precision machining and grinding for tight tolerances
- Assembly jigs to ensure repeatability and throughput
- Surface coating options matched to corrosion requirements
Inspection and Traceability
- Magnetic properties inspection (as required)
- Dimensional checks and visual standards
- Lot control and documentation support for audits
