Engineered with precision NdFeB magnets, offering high holding force and long lifespans for harsh precast concrete environments.
In the global construction landscape, the transition from traditional cast-in-situ concrete to industrialized precast concrete forms the core of modern sustainable building initiatives. Central to this productivity shift is the development of robust, high-holding-force flat magnets. By replacing obsolete mechanical clamping and temporary welding practices, high-performance shuttering magnets stabilize steel and timber frameworks on steel casting tables with millimetric precision.
Magnetic components must withstand extreme shear loads, constant vibrations from compaction tables, and abrasive concrete slurry exposure without losing holding power.
Standard raw magnets decay rapidly when exposed to humidity and alkaline concrete matrices. Custom stainless steel or epoxy encapsulation ensures long-term operational health.
While the initial capital expenditure of magnetic formwork exceeds timber blocking, the system's reusability (>1000 cycles) saves substantial labor and material costs over its life.
A raw NdFeB block magnet disperses magnetic flux evenly around its poles. To adapt this force for industrial holding applications, QCM Magnet designs a customized *magnetic yoke circuit*. By enclosing the neodymium elements within a cold-rolled carbon steel or SUS304 housing, we redirect the upper magnetic flux vectors downward. This structure concentrates the flux lines on the contact face of the steel bed, amplifying the physical holding power by up to 500% compared to a bare magnet. This mechanical concentration enables a compact flat magnet box to achieve a vertical pull force exceeding 2500 kg.

As a key supplier to international construction consortiums, Qianci Magnet operates in strict accordance with recognized structural safety regulations. Our magnetic assemblies are calibrated using high-accuracy testing benches, ensuring that the stated nominal holding forces match actual site performance on clean steel surfaces.
Our production line is governed by ISO 9001 quality management guidelines. To ensure safety, our lifting anchors, clutches, and couplers comply with EU Directive 2006/42/EC and ASTM A370 standards. In lifting operations, maintaining a high factor of safety (typically 3:1 or 4:1) prevents failure from dynamic shocks during transit.
With distribution channels spanning North America, Europe, Australia, and the Middle East, we design components to withstand varied regional curing practices. This includes high-temperature resistance modifications for steam-curing tunnels in Middle Eastern precast facilities and robust corrosion protection for coastal, high-humidity manufacturing yards.

Offering 2400kg (5300 lbs) of holding force, this model is built for precast plants across Europe. It provides the clamping force required to hold thick structural side forms in place during high-frequency vibration cycles.
This 1300kg vertical tensile force neodymium precast concrete magnet is used to secure the side moldings of precast elements, including flat floor slabs and wall panels, helping to maintain formwork geometry.
As precast plants move toward Industry 4.0 automation, the requirements for magnetic tooling are evolving. Qianci Magnet is active in this research and development sector, designing products that integrate with smart construction technologies.
Modern automated precast concrete carousels use robotic arms to pick, place, and lock magnets onto steel beds. We are developing lightweight, compact magnetic boxes with standardized grasping features to ensure compatibility with robotic grippers, reducing cycle times.
To reduce maintenance costs, we are testing thin-film physical vapor deposition (PVD) coatings and high-performance polyurethanes. These materials help prevent concrete adhesion and rust, extending the life of the magnetic assemblies.
Steam curing speeds up precast concrete cycle times, but elevated temperatures can demagnetize standard neodymium magnets. Our engineering team is testing NdFeB formulations with high intrinsic coercivity (Hcj) to allow reliable performance at temperatures up to 180°C.
