Learn MoreThe global construction sector is undergoing a massive shift from traditional cast-in-situ concrete laying to modernized, precision-controlled precast concrete manufacturing. At the heart of this transformation is the integration of heavy-duty magnetic fixing assemblies, often referred to in the industry as 3m magnets (referencing 3-meter formwork profiles and large-scale modular shuttering assemblies).
These systems utilize Neodymium (NdFeB) permanent magnets structured in strategic Halbach arrays or enclosed block arrangements. By exerting massive vertical clamp forces (from 900 kg up to over 2500 kg) directly onto the steel casting beds, they secure formwork barriers with absolute rigidity. Unlike traditional mechanical fastening methods, magnetic formwork requires no drilling, welding, or tapping into expensive steel platforms. This extends the service life of casting beds indefinitely, slashes assembly cycles, and significantly improves labor-use metrics.
How Qianci Magnet (QCM) addresses the demand for sustainable, high-precision modular construction around the world.
Rapid urbanization throughout Europe, Asia, and North America requires accelerated housing and commercial construction. Prefabricated columns, sandwich panels, and pre-stressed hollow core slabs rely on consistent magnetic fixing systems to meet tight developmental schedules.
As rare-earth raw material prices fluctuate, QCM leverages direct vertically-integrated manufacturing lines in China to secure high-purity Neodymium (NdFeB). This ensures steady cost control and dependable lead times for major international precast enterprises.
Modern "green building" standards mandate minimal material wastage. Eliminating disposable formwork screws, anchors, and consumable plywood profiles in favor of reusable steel side-forms locked with NdFeB components cuts waste down to near-zero metrics.
A high-performance shuttering system must operate in challenging environments. Wet concrete slurry is highly alkaline and corrosive, and high-frequency vibration tables can quickly demagnetize low-grade assemblies. QCM tackles these factors through careful materials selection and physical design:
1. Premium Rare-Earth Cores: We utilize top-tier sintered Neodymium-Iron-Boron (NdFeB) permanent magnets. For standard operations, N52 grade cores provide unmatched power. In high-temperature curing environments (such as steam autoclaving), we integrate high-coercivity (SH or UH) series alloys that resist thermal demagnetization up to 120°C–150°C.
2. Anti-Corrosion Encapsulation: The magnetic core is fully sealed within a solid casing using specialized epoxy resin or polyurethane potting. This prevents grout, alkaline wash, or ambient moisture from penetrating the interior. The exterior housing is constructed from either sandblasted carbon steel (treated with a anti-oxidation coating) or marine-grade stainless steel to ensure physical longevity.
3. Patented Mechanical Activation: The design features an integrated spring release mechanism. By using an ergonomic lever rod, the operator can engage (push down) or disengage (pull up) the magnet with minimal effort. This makes adjustments during formwork alignment fast and simple.
Who We Are: Qianci Magnet (QCM) is a specialized production and research facility. We focus on the design and manufacture of shuttering magnets, formwork assemblies, pre-embedded insert magnets, and magnetic concrete chamfer profiles.
Our Business Focus: Our engineering services provide precast concrete magnetic fixing solutions. We help precast manufacturers automate production, reduce physical steps, and achieve higher casting precision.
Our Corporate Strategy: To act as a trusted global manufacturer and supplier of magnetic systems for the precast concrete and industrial automation sectors.
From massive modular multi-story housing developments to intricate civil infrastructure projects, QCM magnetic elements deliver consistency across diverse conditions.
Ideal for rapid housing projects where walls must be cast with precise cutouts for electrical channels, windows, and doors. The 2100kg and 2500kg shuttering boxes firmly secure wood or steel side barriers without shifting under high-frequency vibrators.
Large-scale curved segmented concrete blocks used in modern wind turbine towers require robust formwork support. QCM custom magnetic brackets and adaptors securely align structural contours during complex casting stages.
For skyscraper construction where floor panels require accurate embedded conduits for plumbing, electrical wiring, and lifting hardware. Our embedded magnetic plate fixtures lock these components directly to the steel bed to keep them from shifting during pouring.
Our engineers address common technical, pricing, and operational queries from global buyers.
Shuttering magnet boxes (such as the 2100kg or 900kg variants) are self-contained magnetic clamp systems designed to press down on independent wood or metal formwork profiles. Formwork magnets, on the other hand, often refer to integrated formwork systems where the magnet and the shuttering profile are built together as a single structural unit. This integrated style is typically used in automated production systems with robotic gantry systems.
The choice of pull force depends on the height and weight of the formwork, the thickness of the concrete slab, and the intensity of the vibration equipment used.
• 600kg to 900kg: Ideal for lightweight wall cutouts, windows, and thin concrete partitions.
• 1000kg to 1300kg: Suitable for standard modular house wall panels and slab formwork.
• 1800kg to 2500kg: Designed for thick structural panels, large columns, and heavy pre-stressed elements that require high stability during casting.
Pricing is influenced by:
1. Raw Neodymium Cost: The market price of NdFeB rare-earth elements is the largest cost factor.
2. Housing Materials: Stainless steel housings cost more than standard carbon steel but offer superior wear and rust resistance.
3. Custom Adaptors and Formwork Attachments: Specialized brackets or automated robotic interfaces add complexity to the manufacturing process.
4. Order Volume: Large wholesale orders qualify for reduced unit costs and bulk shipping rates.
To maximize the lifespan of your magnetic assemblies:
• Keep the bottom of the magnetic box clean. Scrape away any concrete slurry or dust, as even a 1mm gap can reduce the holding force by over 50%.
• Avoid hitting the steel casing directly with heavy hammers. Use a dedicated release tool to activate or deactivate the system.
• Apply a light layer of anti-rust oil to the contact surfaces periodically to protect the metal from corrosion.
QCM Magnet manufactures all products in strict compliance with international manufacturing and material standards. Our facilities operate under the ISO 9001:2015 Quality Management System. This ensures that every magnetic box is checked for pull force rating, dimensional accuracy, and shell integrity before leaving the plant.
Our Neodymium materials comply with European Union RoHS (Restriction of Hazardous Substances) and REACH directives. This makes our products safe for export and use in demanding civil engineering applications worldwide.
We continuously research ways to improve the performance of our magnetic systems. Our current development pipeline focuses on:
Integrating simple mechanical sensors that indicate when the magnet is not in full contact with the steel table, helping operators ensure safe setups.
Developing next-generation chrome-free anti-corrosion coatings that offer excellent resistance to harsh environments while minimizing environmental impact.
