High-precision NdFeB permanent magnetic assemblies engineered for concrete formwork, industrial step motors, and precast infrastructure.
In modern industrial engineering, the strategic shift towards lightweight, ultra-high-efficiency materials has redefined the parameters of magnetic component sourcing. Global enterprises across civil construction, prefabricated prefabrication (Precast), and automotive/electric motor manufacturing face the challenge of minimizing operational deadweight while maximizing shear and holding force performance.
Lightweight magnet design is not merely a reduction in material mass; it is a complex discipline of magnetic field containment and circuit optimization. By employing advanced Rare-Earth alloys (such as Neodymium-Iron-Boron NdFeB and Samarium-Cobalt SmCo) encased in lightweight carbon steels or aluminum alloys, modern manufacturers are achieving unprecedented force-to-weight ratios. This optimization is critical for reducing logistical costs, mitigating occupational safety hazards during manual handling on formwork tables, and reducing energy expenditure in dynamic rotating machinery.
Our lightweight systems leverage Finite Element Analysis (FEA) to route magnetic flux line distribution dynamically, concentrating 95% of holding force on the working surface and minimizing stray field loss.
Bridging the gap between structural stability and modular automation with high-performance magnetic assemblies.
Shuttering molds shape edges and openings on flat surfaces using magnetic fixation. Utilizing magnetic fixing in precast concrete component production prevents damage to the platform, enhances work efficiency, reduces labor costs, and promotes economic efficiency as the magnetic fixing devices are reusable.
High-coercivity magnets (N35SH, N38H, N42H) are critical in BLDC stator and rotor designs. These magnets guarantee sustained torque density and structural integrity at extreme operating temperatures up to 150°C, reducing electromagnetic rotor mass.
From magnetic steel chamfer strips to custom lifting socket inserts, our solutions provide precise structural anchoring points. This eliminates the need for welding or drilling into expensive casting beds, protecting capital equipment.
Engineered to withstand the demanding mechanical stresses of automated structural manufacturing.
Standard Neodymium (NdFeB) magnets are prone to irreversible thermal demagnetization at temperatures exceeding 80°C. By implementing grain boundary diffusion (GBD) technologies and optimizing Dy (Dysprosium) additions, our industrial magnets maintain high magnetic flux stability in severe environments. Our motor-focused SH and H grade permanent systems are engineered specifically for stepping and brushless DC (BLDC) motors, resisting demagnetization curves up to 150°C and 120°C respectively.
For ultra-high temperature operations, our high-quality Samarium Cobalt (SmCo) magnets operate seamlessly at up to 350°C, providing exceptional corrosion resistance and linear performance characteristics without requiring outer plating.
Exposure to high-humidity concrete slurries and industrial wash-downs requires robust surface preservation. We utilize advanced plating technologies:

Expert answers to the most common engineering and procurement questions regarding high-performance magnetic assemblies.
Mechanical fixings require drilling, threading, or welding directly onto steel casting beds. This compromises the flatness of the platform and causes permanent deformation over time. Shuttering magnets use high-energy neodymium blocks to create a switchable connection without damaging the steel plate, extending platform lifespan and allowing rapid formwork changes.
Standard 'N' grade neodymium magnets lose magnetic force above 80°C. The suffix 'H' specifies safe operation up to 120°C, and 'SH' specifies safe operation up to 150°C. By adjusting the alloying element ratios (typically by replacing some Neodymium with Dysprosium), these structural magnets resist the demagnetizing fields generated by industrial step motors.
We conduct vertical pull testing and shear resistance tests on dynamic hydraulic test beds. Every batch is certified with magnetic curve testing data, verifying actual magnetic force performance. Buying directly from ISO-certified manufacturers like QCM helps avoid the issues of generic third-party grading discrepancies.
Keep the bottom contact surface clean of concrete residue, rust, and oil. Periodically apply a thin layer of release oil or anti-rust spray. Avoid hitting the magnet core directly with hammers. Using specialized release levers (adaptors) protects the steel housing and preserves internal neodymium alignments.
