SAIXIN® shuttering magnet box is the new magnetic fixture designed for fixing precast concrete formwork, compared to the traditional way of bolted fixing, shuttering magnet box can be disassembled quickly with flexible operation, strong holding force, and consequently improve the work efficiency, reduce man power, low down the wastage of the steel platform, now the shuttering magnet box is used worldly in PC industry.

1. While using shuttering magnet box, it is necessary to avoid sundries at the bottom as the gap will affects the holding force of magnet box and steel platform.

SAIXIN® shuttering magnet box is made of high-performance neodymium material, it have strong holding force.

When the shuttering magnet box work, the suction side at the bottom of the shuttering magnet box is tightly attached to the steel platform. But when there are sundries (such as concrete, grease, film) at the bottom, the shuttering magnet box is not closely attached to the platform, and the holding force will be significantly reduced.

As a prove, we test our SX-1000 shuttering magnet box to study the relationship of holding force and the gap between shuttering magnet box bottom and the platform . We put 0 ~ 10 pieces A4 paper (thickness 0.09 mm) between the bottom of the shuttering magnet box and the platform and then test the holding force with different gap. The test data is as below:

As the picture show, the gap between the bottom of the shuttering magnet box and the platform will significantly influence the holding force, so we recommend customer maintain the shuttering magnet box according to the following methods:

2.Cleaning Method

Before use it, we should confirm the shuttering magnet box bottom and platform is clean and flat. If the bottom have sundries, we can use stainless steel scraper to clean (iron scraper will be attached to magnet, it can't clean up), if it is not easy to clean up material such as hard concrete, we can use polisher to clean. Like the below picture shows: firstly Install polishing brush on the polisher, and then polish the magnet box bottom to make it clean and flat.

3.Handle with care, prevent the magnet damage

Since the shuttering magnet is made of rare earth materials, the material character is similar to ceramics, stiffness and brittle , easily broken.

So that when we use the shuttering magnet box, we should prevent it falling, throwing and avoid using stiff tools (such as iron hammer) to knock, crash, otherwise the magnet box will be of deformation, as the below picture show.


Magnet box deformation

When we remove the shuttering magnet box, please don’t use the metal hammer to knock directly, we should use the lever to pick up the switch firstly, and the holding force of the magnet box and the platform is reduced dramatically, then the shuttering magnet box can be moved easily by hand like the below picture:

When we press the shuttering magnet box, also can’t use metal hammer to knock directly, suggest use the foot press down, rely on human body gravity press down, but can’t stomp, prevent slip and hurt.


                  Right                                              Wrong

 If you must use a tool, please use a rubber hammer to gently tap.


4.Magnet Box Collection

After use, the shuttering magnet box should be cleaned up and placed on the stainless steel cart,to keep it clean and easy to use next time.The shuttering magnet box can’t be placed on the iron cart, because the shuttering magnet box will be attracted to iron cart.


5. Magnet Box Storage

5.1.When the magnet box is not used for a long time, after cleaning, we should clean the bottom surface with anti-rust oil (such as mobil, Great Wall, etc.), in this way, we can prevent the magnet block from rusting since rusting will influence the magnet box holding force too.

5.2. Magnet box work and storage temperature should not be higher than 80 ℃, the surrounding should have no strong acid, strong alkali and other corrosive media.

In conclusion,as long as we can do as per above protection, cleaning, and storage measures, we believe our SAIXIN®️ magnet box must be durable and trustworthy!
