On the prefabricated construction site, when the crane lifts several tons of concrete wall panels and places them precisely in place, few people notice the palm-sized metal boxes in the corners of the steel molds. These devices, called shuttering magnets, silently guard the molding accuracy of each shear wall. They are like invisible hands, firmly "holding" the mold, allowing the "skeleton" of the high-rise building to remain motionless in the torrent of concrete.

Core Challenge: "Pain of Mold" of Prefabricated Shear Walls

In traditional prefabricated shear wall production, fixed side molds often rely on welding or bolt mechanical fixation. This method is not only inefficient, but also has three major pain points:

1. Accuracy out of control: uneven manual tightening force causes mold displacement and wall thickness error exceeds the limit;

2. Damage to the mold: high welding temperature deforms the steel mold and the bolt holes permanently damage the flatness of the tabletop;

3. Efficiency bottleneck: The installation of a single wall panel mold takes up to 1-2 hours, which seriously slows down the production line rhythm.

The birth of Shuttering Magnets has completely reconstructed this process - magnetic adsorption replaces physical destruction, bringing about a qualitative change in the fixing method.

Magnetic black technology: How can a small magnetic box bear a huge force?

▶ Structural design: a precise system that can achieve great results with just a little effort

- Permanent magnetic core: using NdFeB N52 grade strong magnets, the adsorption force of a single box can reach 450-2100kg;

- Magnetic circuit control: original magnetic shielding steel shell structure, adjusting the magnetic circuit air gap through the switch button to achieve "adsorption/release" switching;

- Mechanical adaptation: double-sided high-strength fastening screws (8.8 grade) can be connected to various side molds such as angle steel and channel steel.

▶ Operational revolution: three steps to complete the fixation of hundreds of tons

1. Positioning: The magnetic box is placed in the preset position of the steel mold table;

2. Activation: Press the button, and the magnet instantly adsorbs the tabletop (adsorption force↑);

3. Clamping: Rotate the side screws to clamp the L-shaped angle steel side mold.

When disassembling, you only need to use a special crowbar to gently lift the button. The magnetic force is attenuated by 90% and can be removed with bare hands.

4. Win-win situation of safety and environmental protection

- Zero spark operation: eliminate the risk of welding fire;

- Noise reduction and waste reduction: noise is reduced by 40%, and the amount of wooden formwork is reduced by 70%.

Therefore, the magnetic box is not only a tool, but also the fulcrum of lean production of prefabricated buildings.
