What Exactly Is a Shuttering Magnet? Demystifying the Basics
A магніт для опалубки is a smart, switchable permanent magnet system designed to hold formwork securely without the need for traditional fasteners like bolts or clamps. It is a useful магніт для будівництва,encased in a tough steel housing, it delivers a strong, reliable grip that makes setting up precast concrete molds faster and safer.
Core Components
- Magnetic Array: The heart of the system, usually high-grade неодимовими (NdFeB) магнітами, providing powerful holding force.
- Activation Button: A handy switch that turns the magnet’s holding force on or off, allowing easy positioning.
- Adapter Interfaces: Various attachments or mounts that connect the magnet to different formwork types (steel or wooden).

How It Stands Out from Traditional Clamps
| Особливість | Traditional Clamps | NBAEM Shuttering Magnets |
|---|---|---|
| Сила утримання | Variable, often weaker | High-grade NdFeB magnets, up to 3,200 kg |
| Installation | Bolts, screws, manual tightening | One-button activation, no tools needed |

With NBAEM’s advanced neodymium magnets, the shuttering magnet system offers a firm, dependable hold that beats traditional clamps in both strength and convenience. It’s the go-to solution for modern precast concrete formwork fixing.
How Shuttering Magnets Work: From Activation to Secure Hold
Shuttering magnets use a clever magnetic circuit principle to switch between two modes for easy positioning and strong clamping. In the off-mode, the magnetic flux is contained inside the steel casing, so you can place and move the magnet freely on the steel platform without it sticking. When you’re ready, pressing the activation button switches the magnet on, redirecting the magnetic flux outwards to grip tightly onto the steel surface and hold the formwork firmly in place.
Here’s a simple step-by-step on using these magnets effectively:
- Place the shuttering magnet onto your steel platform or table.

Since shuttering magnets rely on magnetic attraction, they won’t stick to aluminum or wooden platforms. You’ll need steel adapters or alternative clamping methods for such setups.
Quick Maintenance Checklist
| Task | Frequency | Нотатки |
|---|---|---|
| Surface cleaning | Before each use | Remove dust, rust, oil |
| Magnetic face inspection | Daily | Check for chips, cracks |
| Зберігання | After work | Keep dry, separated |
| Rust treatment | As needed | Use wire brush or rust remover |
| Functional test | Weekly | Confirm switch and hold force |
Following these basic maintenance and troubleshooting tips ensures your shuttering magnets deliver reliable strength and save time on every concrete formwork setup.
Selecting the Best Shuttering Magnet: Factors to Consider
Choosing the right shuttering magnet depends mainly on your project’s holding force requirements and the type of formwork you’re working with. Make sure the magnet’s strength matches the weight and material of your molds to avoid slips or repositioning during concrete pouring.
Budget versus durability is another big factor. While cheaper generics may save money upfront, higher-quality magnets like NBAEM’s 2,100 kg holding force model offer longer life, better performance, and quicker returns on investment through fewer replacements and less downtime.
Look for quality markers such as NdFeB purity and certifications to ensure you’re getting genuine switchable permanent magnets built for heavy-duty use. NBAEM magnets use premium neodymium rare earth materials, guaranteeing strong, reliable magnetic holding force combined with easy switch-off functionality. This makes them versatile and safe for precast concrete setups.
