Electric Box Insert Magnet for Precast Concrete

What is Electrical Box Insert Magnet?

An Electric Box Insert Magnet for Precast Concrete is a specialized magnetic device designed to securely hold electrical boxes (such as junction boxes, outlet boxes, or switch boxes) in place within precast concrete forms during the casting process. 

LSC's electrical box magnets have been used in the precast concrete industry for many years and have proven their worth in practice. With the combination of rubber bodies and integrated magnets, almost all geometries and solutions are possible. Easy installation and removal in the electrical box contribute to an efficient and streamlined process. Powerful integrated magnets hold the insert in the exact position. For empty conduit magnets, the magnet body will leave a groove in the concrete after removal. Through reasonable magnetic structure design, we can make the fixed magnets into various shapes, which can be used with pipes and wire boxes of different shapes and sizes. Use LSC to insert magnets to fix the embedded parts, and the magnets to fix the parts to prevent sliding and sliding. Our products are durable, cost-effective, easy to use, and efficient.

Advantages and features:

1. Material and structure: Generally, consists of high-performance NdFeB magnets, a steel housing and a threaded rod. The steel casing not only protects the magnets from external damage, but also transmits the magnetic force to the contact surface, resulting in a stronger attraction force.

2. Magnetic design: Reasonable magnetic circuit design and mature production process ensure quality and durability.

3. Easy to operate: The magnetic insert design makes the installation and removal of the electrical box easy and fast, ensuring high efficiency during use.

4. Reusable: These magnets are reusable, cost-effective and easy to handle.

5. Safety: The use of magnetic components reduces the need for manual clamping or tightening, reducing the risk of construction accidents.

6. Environmental adaptability: The surface of the magnet is usually coated with anti-corrosion coating, which can work well in an environment of up to 80℃.

Application of Electrical Box Insert Magnet Precast Concrete 

1. Precast Concrete Components: The Electric Insert Magnet is widely used to secure electrical boxes and other components in the construction of precast concrete wall panels, beams, columns and other components. It ensures the accuracy of the positioning of these components during the concrete placement process, thereby improving the quality and consistency of the assembly.

2. Electrical Installation: The insert magnet is made of permanent neodymium magnets which, when combined with steel, rubber or nylon, can be formed into almost any shape to secure an embedded part in precast concrete production.

When using, the magnetic surface fixes on the platform or steel formwork, the other side fixes the embedded part, due to the strong suction force, the embedded part can stay in the precast concrete member precisely.

3. Green Building Model: With the transformation of the construction industry to a green building model, precast concrete pouring has become an energy-saving, environmentally friendly and cost-effective construction method. Electric Box Insert Magnet plays an important role in this process.

How to Maintain the Insert Magnet?

(1) To avoid damage to the inserted magnet, do not collide and hit with a hard tool.

(2) The contact surface should be kept clean and smooth.

(3) After use, clean the insert magnet. The maximum working and storage temperature should be lower than 80ºC, and there should be no corrosive media around.
