Target Applications: Precast Concrete & Modular Construction Engineering

How QCM Magnet revolutionizes modern off-site construction productivity and reusable formwork systems.

The worldwide precast concrete construction industry demands reusable, zero-damage formwork solutions. Traditional welding or bolting methods ruin expensive steel formwork tables, increase labor hours, and lower throughput. QCM Magnet’s specialized Shuttering Magnets & Magnetic Formwork Systems solve these pain points seamlessly.

Shuttering Magnet Boxes

Ranging from 450 kg (1000 lbs) to 2500 kg (5500 lbs) holding force. Activated via a simple push-button mechanism, these magnetic boxes lock steel side formwork securely against heavy concrete vibration during casting.

Magnetic Chamfering Strips

Available in triangular, trapezoidal, steel, and magnetic rubber compositions. Designed to quickly form 45-degree bevels on concrete wall edges without mechanical fasteners.

Insert & Socket Magnets

Engineered to hold threaded lifting sockets (M10, M12, M20), anchor plates, and conduits securely to steel formwork beds during slurry pouring.

Technical FAQ: Neodymium Magnets & Industrial Assemblies

Expert answers regarding performance preservation, logistics safety, custom engineering, and application limits.

Q1: What is the maximum safe operating temperature for Neodymium magnets before irreversible demagnetization occurs?
Standard N-series Neodymium magnets operate up to 80°C (176°F). Exceeding their specific Curie point or Maximum Operating Temperature leads to permanent flux loss. For elevated temperature applications, QCM Magnet produces high-coercivity grades: M (100°C), H (120°C), SH (150°C), UH (180°C), EH (200°C), and AH (230°C).
Q2: How do shuttering magnet boxes achieve thousands of kilograms of holding force in compact steel housings?
Shuttering magnets utilize internal multi-pole iron circuit designs (such as flux concentrating steel casing). By routing magnetic field flux through high-permeability low-carbon steel plates directly onto the steel casting bed, the effective holding force is amplified exponentially compared to an open-air magnet.
Q3: What regulations apply to shipping high-strength magnetized materials by air freight?
According to IATA Dangerous Goods Regulations (PI 953), air shipments of magnetic products must not exceed a magnetic field strength of 0.00525 gauss measured at a distance of 4.6 meters (15 feet). QCM Magnet provides certified magnetic shielding packaging (using sheet metal liners and foam spacing) for compliant, hassle-free global air delivery.
Q4: What is the main difference between Neodymium (NdFeB), Samarium Cobalt (SmCo), and Alnico magnets?
NdFeB offers the highest magnetic strength per volume at reasonable cost but lower thermal limit. SmCo provides extreme temperature stability (up to 350°C) and superior corrosion resistance without coating, ideal for aerospace/defense. Alnico has lower coercivity but exceptional magnetic stability across extreme temperatures (up to 550°C) and classic acoustic resonance characteristics ideal for guitar pickups.
Q5: Can QCM Magnet customize pot magnets or precast magnetic formwork to existing drawing dimensions?
Yes. We provide complete OEM/ODM engineering services. You can send your DWG, STEP, or PDF technical drawings. Our engineering team conducts finite element magnetic field modeling to optimize hold force, reduce weight, and deliver prototype samples rapidly.
