High-performance NdFeB magnetic components engineered for London's leading smart automation, infrastructure, marine salvage, and precision commercial fit-out industries.
London has rapidly transformed into a focal point for precision engineering, smart green infrastructure, and advanced tech start-ups. From the industrial developments along the Thames Gateway to the aerospace, acoustic engineering, and robotic laboratories in Greater London, the demand for high-grade magnet assemblies has never been higher.
Standard raw magnets are rarely sufficient for high-stress applications. They require expert mechanical integration—such as steel pots to channel magnetic flux, rubber coatings for anti-shear performance, and specialized hardware fixtures. Local mechanical engineering consultancies, commercial display designers, and robotics development teams in London require dependable supply chains that balance structural precision, raw magnetic power (such as grade N52 Neodymium), and long-term cost stability.
Working alongside Zhejiang Laysun Magnetics Ltd., local UK buyers bridge the gap between custom British engineering specifications and the scale of high-efficiency Chinese manufacturing.
Founded in 1999, Zhejiang Laysun Magnetics Ltd. is a national high-tech leader specializing in the development, research, production, and global export of high-performance rare earth NdFeB magnets and integrated magnetic systems.
Operating from our massive 100,000 square meter factory in Suining, Sichuan, we focus on providing customized, stable magnetic products for electric vehicles, aerospace systems, high-efficiency industrial motors, and consumer electronics. Our vertical integration—spanning raw material processing, chemical coating, CNC casing fabrication, and magnetic path optimization—ensures that every magnet assembly leaving our dock complies with international QA/QC structures.
By prioritizing values of Quality, Credibility, Technology, and Innovation, we support design engineers globally. Whether you need standard pot magnets or optimized multipole Halbach arrays, our structural calculations ensure optimal flux concentration and minimum weight.
Evaluating the strategic advantages of China-based factory production compared to local Western distributors.
China processes over 80% of global rare earth materials. Direct sourcing with Laysun Magnetics eliminates multiple middle-tier markups, providing stable pricing structures for high-grade Dy-containing (Dysprosium) high-temperature magnetic materials.
Our in-house CNC machining and automated encapsulation lines allow us to build custom steel cups, threaded collars, hooks, and multi-pole housings to match your precise 3D CAD engineering designs.
Our production aligns with ISO 9001, ISO 14001, and IATF 16949 standards. All raw magnetic materials, steel housings, and adhesives undergo strict chemical compliance checks for RoHS, REACH, and UKCA certification.
How our custom magnet assemblies power modern technology sectors from local London infrastructure to international supply chains.
Providing high-torque density magnetic rotors, stators, and custom end-effector couplers designed to support automated warehouse lines across London's industrial depots.
Optimized micro-magnetic rotors designed for maximum strength-to-weight ratios, minimizing magnetic drag and increasing drone flight durations.
Our NdFeB permanent magnets offer the thermal resistance (UH/EH/AH grades) required to withstand structural temperatures inside drive motors and regenerative braking systems.
High-torque brushless DC motor components configured with segmented magnets, reducing eddy current losses and heat output.
High-volume production of magnetic rings for mobile accessories, voice coil motors (VCMs), and acoustic transducers.
Sealed, chemical-resistant magnetic assemblies developed for washing machine drainage pumps, domestic refrigerator doors, and smart kitchen sensors.
To serve our European and UK clientele, we have optimized our supply chain channels. Our headquarters and primary engineering teams are in China, allowing us to manage large production capacities. Additionally, we coordinate international shipping processes to ensure smooth customs clearance for freight entering London gateways (such as Heathrow Cargo Hub or London Gateway Port).
We work closely with UK engineering partners to manage the logistics process, offering DDP (Delivered Duty Paid) shipping to minimize administrative overhead for London procurement officers.
For custom engineering and high-volume orders, we provide fast sampling (within 7–10 days) and dynamic prototyping to ensure your components are validated before volume production begins.
We hold certifications that reflect our commitment to precision, durability, and raw material reliability.
International quality management system governing all sintered NdFeB manufacturing processes.
Strict enforcement of ecological limits, waste minimization, and green chemistry standards.
High level system validation, matching structural requirements for electric drivetrains.
The cost of magnet assemblies is determined by several factors, including the grade of raw NdFeB magnet used, assembly materials (such as low-carbon steel casing or 304 stainless steel), mechanical complexity, surface treatment coatings, and order volume. The table below outlines our typical custom structural tiers:
| Assembly Structure Type | Material Configuration | Typical Applications | Relative Cost Factor | Min. Pull Force Range |
|---|---|---|---|---|
| Standard Pot/Cup Assembly | NdFeB (N35) + Q235 Zinc-Plated Steel | General suspension, ceiling fixtures, magnetic fixtures | Baseline (1.0x) | 12kg - 120kg |
| Rubber Coated Assembly | NdFeB (N42) + Santoprene Rubber Cover | Automotive mounting, exterior signage, scratch-prone surfaces | 1.3x - 1.5x | 8kg - 85kg |
| Threaded Stud Lifters | NdFeB (N45) + Hardened Steel Shell | Industrial warehouses, lifting cranes, machine workshops | 1.4x - 1.8x | 150kg - 1000kg |
| Precision Motor Rotor | NdFeB (38SH - 45UH) + Stainless Sleeve | High-RPM brushless motor, EV traction units, wind power | 2.5x - 3.5x | Engineered Spec |
| Hermetic Marine Assemblies | NdFeB (N48) + PTFE or Double Epoxy Coat | Thames River surveys, subsea instrumentation, chemical mixers | 1.8x - 2.2x | 45kg - 350kg |
*Note: The relative cost factor is an index based on our standard production scale. Please contact our engineering department for a detailed quote based on your specific drawings and tolerances.

Answers to technical, regulatory, and logistics questions from our global engineering team.
A raw magnet (such as a sintered block or disc) displays a magnetic field in all directions. A magnet assembly incorporates ferromagnetic housings, steel plates, or poles to channel and focus the magnetic flux to a specific surface. This design can significantly increase the effective holding force (up to 3 or 4 times the strength of a raw magnet of equivalent size) and helps protect brittle magnetic materials from mechanical impact.
We source raw materials that comply with European and UK chemical safety guidelines. All assemblies are checked for RoHS and REACH restrictions (specifically covering heavy metals like lead and cadmium, and chemical binding resins). We provide full declarations of conformity and material test sheets with our export shipments.
Standard Nickel-Copper-Nickel (Ni-Cu-Ni) plating provides basic indoor corrosion protection. For marine settings or humid conditions, we recommend Epoxy coating, Teflon coating, or wrapping the NdFeB core in Santoprene rubber or a fully welded 316 stainless steel casing. This helps prevent oxygen and water from degrading the neodymium structure.
For custom prototypes, lead times typically range from 7 to 12 working days depending on mechanical complexity. Mass production runs usually take 20 to 30 days, followed by air freight (5–7 days) or sea freight (approx. 35 days to London Gateway). We offer DDP (Delivered Duty Paid) shipping to simplify the import process for our UK clients.
Standard NdFeB material grades (N-grades) can start to lose magnetic output at temperatures above 80°C. For industrial environments, we utilize high-coercivity grades such as M (up to 100°C), H (up to 120°C), SH (up to 150°C), UH (up to 180°C), or EH (up to 200°C). We work with customers to select the appropriate grade based on their specific operating temperatures.
