Explore our high-performance engineered magnetic assemblies, designed specifically for rapid precast concrete component production, structural anchoring systems, and precision electrical guitar applications.
Magnetic materials are the invisible backbone of modern industrial electrification and automated structural systems. From the high-coercivity sintered Neodymium-Iron-Boron (NdFeB) blocks driving electric vehicle drivetrains to the heavy-duty magnetic fixtures enabling rapid construction of precast concrete walls, the demand for precision magnetic arrays is growing exponentially. In this landscape, magnetic properties such as maximum energy product ((BH)max), intrinsic coercivity (Hcj), and operating temperature stability are critical variables that dictate engineering success.
"The shift toward automation in off-site precast concrete construction requires clamping systems that can handle extreme mechanical stresses without relying on drilling or welding, making reusable shuttering magnets essential."
China remains the unmatched global hub for magnet manufacturing due to its comprehensive rare earth supply chain integration. Unlike regions that rely on imported raw oxides, Chinese manufacturers possess vertical processing capabilities—from mined ore separation of Neodymium, Dysprosium, and Terbium to automated sintering, vacuum melting, and surface coating processes (such as Ni-Cu-Ni or Zinc electroplating).
Furthermore, this supply chain concentration reduces raw material volatility, allowing Chinese companies to pass cost benefits and quality guarantees directly to global buyers. In precast magnet manufacturing, this enables high-strength steel housings, precise structural machining, and custom magnetic array designs (such as Halbach Arrays) to be offered at competitive price points.
Advanced magnetic materials are highly tailored to their target physical applications. Our manufacturing focus bridges the gap between raw magnet material production and ready-to-use mechanical-magnetic hybrid tools.
Shuttering magnets dynamically secure wooden, steel, or aluminum formwork profiles directly onto steel casting beds without damaging the costly platforms, reducing setup times by up to 70%.
By arranging magnets in a spatially rotating pattern, the magnetic field is concentrated on one side of the array while cancelling the field on the other, ideal for high-efficiency motors and linear sensors.
Cylindrical Alnico (Aluminium-Nickel-Cobalt) alloy magnets provide smooth, vintage acoustic outputs. Alnico grades 2, 3, 5, and 8 are precision cast to ensure uniform magnetic induction across string lines.
Global procurement managers evaluate suppliers on consistency, dimensional accuracy, and delivery lead times. A common paint point is magnet degradation over prolonged exposure to construction environments—impact forces, moisture, and alkaline concrete residues can quickly compromise standard NdFeB coatings.
To mitigate these degradation factors, our manufacturing plants utilize advanced sealing technologies. For example, shuttering magnet boxes are built using high-strength carbon steel shells that encase the magnetic core with specialized epoxy resin or laser welding. This prevents the ingress of fine particulate matter, extending the operational life of the magnetic assemblies to over several thousand casting cycles.
Additionally, pull tests are executed on customized automated testing beds, providing transparent certification of the exact holding forces before dispatch.
Engineered to provide reliable holding force and easy mechanical release, these core shuttering boxes streamline structural concrete wall production.

China controls over 85% of the global supply chain for raw rare earth elements (specifically Neodymium and Dysprosium). This direct control allows Chinese factories to optimize manufacturing parameters directly from the refining phase, resulting in superior magnetic grades (like N52, 50M, 48H) at significantly lower raw material costs. Furthermore, integrated testing facilities ensure strict consistency in dimensional tolerance and pull force validation.
The holding force depends on the height and weight of your concrete side panels. For low elements (under 100mm height), a 600kg to 900kg shuttering box is typically sufficient. For standard wall panels ranging from 100mm to 300mm, a 1300kg to 2100kg (4600 lbs) box is recommended to withstand the lateral hydraulic pressures of wet concrete during vibration. For complex massive structural elements, multiple 2500kg (5500 lbs) boxes should be paired.
Standard NdFeB magnets can demagnetize if exposed to temperatures above 80°C (176°F) or if the internal alloy is corroded by moisture. To prevent this, we utilize high-coercivity magnet grades designed for higher thermal limits (like SH or UH ratings) if hot-curing processes are used. Additionally, our fully-sealed carbon steel or stainless steel housings prevent concrete water and chemical agents from reaching the core.
