A concrete form magnet is a specialized type of high-strength magnet designed to securely connect and precisely align concrete forms and molds with steel structural elements such as columns, beams, slab tables, and pouring beds during the processes of concrete pouring and curing. Insert Magnets, one of the most essential accessories in the precast concrete industry, are magnetic components utilized in precast concrete production to secure formwork, create voids, and fix concrete inserts.

Insert Magnets comprise NdFeB magnetic rings, steel housings, and threaded rods. The steel housing not only shields the magnetic ring from external damage but also concentrates the magnetic force on the contact surface, generating a higher attraction than an isolated NdFeB magnet. Typically fabricated from high-performance, high-grade NdFeB magnets, the steel casing and rod surfaces are coated with a nickel-copper-nickel (NiCuNi) or zinc layer to provide additional protection.

The advantages of Insert Magnets include:

1. Powerful magnetic force and unique design, facilitating easy operation.

2. Reusability and durability, leading to long-term cost savings.

3. Rapid positioning for increased efficiency and cost-effectiveness.

4. Enhanced quality of precast concrete components.

5. Sufficient magnetic strength to accurately position and secure embedded components during concrete placement or vibration, ensuring safe lifting operations.

To maintain Insert Magnets and ensure safety precautions: avoid mortar covering the surface of the magnetic ring to preserve magnetic force; ensure that the operating and storage temperature of Insert Magnets remains below 80°C, as high temperatures may cause the magnetic force to weaken or be lost entirely.
