The 1300kg vertical tensile force neodymium precast concrete magnet is commonly used to hold the side moldings of precast concrete elements (e.g. flat floor slabs, walls) in place.
Get France PricingThe French precast concrete sector (Béton Préfabriqué) is undergoing a profound structural evolution driven by the strict RE2020 (Réglementation Environnementale) directives, which prioritize carbon reduction, energy efficiency, and minimized jobsite waste. Industrial prefabrication plants in regions like Île-de-France, Auvergne-Rhône-Alpes, and Nouvelle-Aquitaine are actively scaling production of structural walls, double walls (prédalles), and modular elements to meet these goals.
To maintain profitability under strict labor costs and compressed schedules, French precast factories are shifting away from traditional welding and drilling on formwork tables. This is where high-precision magnetic shuttering technologies provide significant operational advantages. By replacing mechanical fasteners with neodymium-based magnetic clamping boxes, plants preserve their steel formwork beds, accelerate setup times by up to 70%, and ensure millimeter-level structural tolerances.
QCM Magnet delivers custom magnetic assemblies designed to resist high-frequency vibrations from compaction tables, ensuring consistent holding forces (ranging from 450 kg to 2500 kg) that conform to European quality and safety guidelines.

Understanding the mechanics of neodymium rare-earth magnetic systems for concrete casting beds.
We utilize high-grade N35 to N52 NdFeB magnets. To resist thermal demagnetization in French autoclaves or steam-curing tunnels, we treat our magnetic alloys with Dysprosium (Dy) additions, increasing the intrinsic coercivity (Hci) to withstand temperature thresholds up to 80°C (standard) and up to 120°C for custom thermal curing profiles.
The aggressive chemistry of concrete slurry, combined with frequent washing, demands robust protective coatings. Our shuttering boxes feature multi-layered protection, including black epoxy coatings, zinc electroplating, and triple-layer Ni-Cu-Ni plating, coupled with hermetically sealed stainless steel housings to prevent rust and mechanical wear.
Selecting the correct magnetic force is critical for system safety. For thin filigree slabs (60–100mm), 900kg to 1000kg forces are recommended. Standard solid wall panels (100–200mm) require 1300kg to 1800kg. Heavy, highly-vibrated structural beams and columns require up to 2100kg to 2500kg of pull force to prevent slippage.

By sourcing directly from our advanced production facilities in Ningbo and Xiamen, French buyers bypass intermediary margins. We secure NdFeB raw alloys directly, providing stabilizing raw material pricing even during market fluctuations.
Port-to-Port Delivery Options: Daily departures from Ningbo/Shanghai ports directly to Port of Le Havre or Port of Marseille-Fos. Typical ocean transit times range from 28 to 35 days, with DDP (Delivered Duty Paid) arrangements available to handle all customs clearance, EU duties, and final truck logistics to your warehouse.
Quality Assurance Inspection: Every batch is tested using 3D coordinate measuring machines (CMM) and magnetic flux scanners to verify structural dimensions and minimum holding force limits prior to packing.

Each shuttering box is designed with a closed magnetic array housing. To maintain optimal contact, operators should clear the steel casting bed of stray aggregate or cured paste before placing the magnetic box. Spraying a thin film of release agent or shuttering oil onto the box's outer casing helps prevent concrete adhesion, making cleanup easier.
Under normal operating parameters and regular maintenance, the magnetic decay of our N-grade NdFeB cores is less than 1% over a 10-year period. The mechanical shell, springs, and internal mechanisms are designed for thousands of cyclic compression and release actions, easily outlasting standard wooden formwork assemblies.
Because NdFeB magnetic fields exert substantial downward pull (e.g., 2100kg), lifting the box directly by hand is virtually impossible and presents a safety hazard. Our release levers use mechanical advantage to lift the magnetic block off the steel bed, safely switching off the holding force for quick relocation.
Yes. We have an in-house engineering team that creates custom adaptor brackets to attach our standard magnetic boxes directly to specific wooden, plastic, or steel formwork molds. Send us your profile CAD files (.dxf or .step), and we will design a custom solution for your facility.
