Premium architectural grade precast shuttering magnets and precision machined steel formwork components.
In modern structural engineering and industrial manufacturing, precision-engineered magnetic circuits have revolutionized concrete prefabrication and motor assemblies. Specifically, the term Curved Magnets encompasses specialized permanent magnets—such as NdFeB arc segments utilized in high-performance rotary engines—and curved magnetic fixtures engineered for circular formwork systems. In both realms, maximizing magnetic flux density while ensuring mechanical durability is the key design challenge.
Arc and curved magnets pose complex manufacturing demands due to their non-rectilinear geometries. Unlike standard block magnets, curved magnets require directional orientation matching their radial, diametrical, or multi-pole profile. By optimizing the arc angle and thickness gradient, manufacturers can focus the magnetic fields towards a localized working face. In industrial precast systems, curved magnetic templates enable the seamless formation of structural columns, wind turbine bases, and subterranean drainage systems.
Expert Insight: Thermal stability plays a critical role in high-stress applications. While standard NdFeB magnets operate reliably up to 80°C, custom formulations incorporating Dysprosium (Dy) and Terbium (Tb) enable operation up to 200°C without permanent demagnetization, ensuring performance under steam curing protocols or intensive rotary engine stresses.
Engineered for seamless steel bed integration with variable pull-force capacities to optimize concrete prefabrication.
The manufacturing of advanced curved magnets and precast concrete fixing systems requires rare-earth raw material security, precise metallurgical control, and world-class mechanical processing. China's integrated supply chain, centered around resource hubs like Ningbo and Ganzhou, controls over 80% of global rare earth processing, providing Qianci Magnet (QCM) with unmatched raw material access and consistency.
Direct sourcing of neodymium oxide and iron-boron alloys ensures highly stable remanence (Br) and intrinsic coercivity (Hcj) values, preventing deviations from batch to batch.
Equipped with advanced CNC machining centers and Wire EDM slicing equipment, we can achieve geometric tolerances for curved segments as narrow as ±0.01mm, ensuring zero-gap fits.
Furthermore, our advanced anti-corrosion treatments (including Multi-layer Ni-Cu-Ni, Epoxy coatings, and passivated Everlube) are designed to withstand harsh concrete slurries and chemical exposure, extending product lifespan by up to 300% compared to non-optimized alternatives.

Become a global leading manufacturer and excellent service provider of magnetic solutions for the precast concrete industry.
The scope of magnetic components has expanded from simple holding devices to complex integrated modules within smart factories and high-efficiency machinery.
As precast concrete factories move towards automated assembly lines, magnetic shuttering boxes are being redesigned to interface with robotic grippers. This requires tighter geometric tolerances and standardized top buttons, enabling robots to position, activate, and release magnets programmatically.
Modern city designs demand organic, fluid architectural shapes. Conventional straight formwork is insufficient for creating curved columns, arched panels, and circular structural elements. QCM's customizable curved magnets and magnetic chamfers fit dynamic, curved casting profiles seamlessly, preventing concrete leakage and yielding smooth concrete surfaces.
In clean energy sectors, curved magnets are central to permanent magnet synchronous motors (PMSM) used in electric drivetrains and wind generators. Minimizing cogging torque and maximizing power density depends directly on the geometric and magnetic precision of the curved segment magnets.
Qianci Magnet products undergo rigorous international compliance testing to meet safety and structural requirements worldwide.
