Shuttering Magnet (Shuttering Magnet for Precast Formwork) Introduction
Precast concrete magnets are very popular in modern civil engineering. In the past 5 years, some conventional magnets were used to position and fasten the formwork, but considerable mechanical loads with a hammer were required, which destroy the surface of the expensive formwork tables and fragile neodymium magnet as well.

In order to facilitate the precast concrete formwork industry, GME is developing and manufacturing our own shuttering magnet to solve this problem successfully.
Our shuttering magnet also is known as button magnets and magnetic boxes. It is consists of a metal casing, a magnetic system, and an effective on/off button, which provides quick operation leading to improved efficiency when setting out and remove the formwork. Shuttering Magnet. And with customized adaptors, Shuttering Magnet provides an ideal solution for almost all kinds of precast concrete formwork structures and construction for wood, aluminum, and steel shutters.
All GME shuttering magnets have extraordinarily high magnetic power more 250 times than their dead weight. Among them, Shuttering magnet 1800KG and 2100KGS is a large size for steel precast concrete platform.

The GME shuttering magnet have an automatic system to activate and deactivate the magnetic field. By application of this precast magnet box, the working time and cost will be reduced and the same workers could produce more concrete walls in a shorter time. Under the same artificial conditions, the use of the shutter magnet system can increase the production capacity by 7 times

Key Benefits Of Shuttering Magnets:
1.Easy installation and effortless operation. Your workers could choose a fixed position at will and quickly build concrete formwork according to individual architectural design. Significantly save complexity and time and cost on the installation of magnetic formwork(up to 70%).
2.Universal use for mass production of concrete products, and piece different shape and size concrete elements of all forms on the same steel table. Excellent applicability, the same prefabricated formwork magnet can be adapted to different concrete formworks. You do not need to have a lot of different forms for different products. The same magnet can be used for different purposes and in different ways. You only need a set of magnets, adapters for different height boards, and a steel table. Your workers could contemporaneously build different concrete formworks at one time; even during the building process, your workers could adjust the concrete formwork.
3. Integrated threaded holes M12 and M16 to adapt formwork and customized adapters, to fix all kinds of side-formwork including wood, steel, and aluminum formworks, eliminates the need for welding, shuttering magnets does not damage the steel table. Avoid welding or bolting to the formwork table therefore preserving surface finish and reduce direct damage to the concrete platform in the working.
4.No welding process is required, and the magnetic force of the magnet can be used to fit the template. Avoid welding or bolting to the formwork table therefore preserving the surface finish. No need for electric welding, you can save high energy consumption.
5.10-Year-long service life and reusable. Low cost. Short payback period.

Structure and Elements of Shuttering Magnets:
The Shuttering magnet assembly consists of steel Casing and fixing screws and a switchable magnetic block or magnetic core (certain designed magnetic circuit) which is made of some strong neodymium magnets and steel plates.
This magnetic core provides very much strong adhesive force to the precast concrete tables. There is a control ON/OFF button on the top of the shuttering magnet, to open or close the magnetic power.

1.Magnet on/off Switch:
1.Stainless steel, Lathe fine grinding,
2. Over 100,000 fatigue simulation experiments, avoid any deformation and malfunction.
3.Humanization design, quick switch (on/off) the magnetic field.

2.Fixing Screws: (Applicable national standard)
Fixing screws can be utilized to secure a different kind of side rails and blackouts
1. Production according to the standard of GB /T 15389-94-GB.
2.Strength ≤1000 Kg: M12
3.Strength>1000 Kg: M16 

3.Strong Neodymium Magnet
Many competitors add more 12% Lanthanum Cerium ingredient in the neodymium magnet when production. 6-8% costs can be saved; by this formula, the same Remanence (Br) is the same to Chinese standard, but its Coercive Force (Hcb) and Intrinsic Coercive (Hjc) is much less and its magnetic field will decrease about 10-15% after 6-10 months.
Neodymium Magnet occupied more than 50% cost shuttering magnet. It is the most important element of this product. The most advantage is that Neodymium Magnet is produced and quality controlled by our own since 9 years ago, certificated by GB/T19001-2016 IDT IS09001:2015 and TS16949. Our material is from Shanxi Province, its performance is higher about 1 grade, but expensive a little. Our warranty is 3 years if proper use.

Why the magnet can create more 200 times stronger than its dead weight?
After a reasonable magnetic circuit design, multiple pieces of strong NdFeB magnet with the same magnetic pole are forcibly fixed in a relatively small space by screws. There is a Q235 magnetic permeable block between the magnets, to guide the repulsive force of the same poles in the same direction and perpendicular to the mold table. Multiple magnetic pole lines form a stable magnetic field and a very high magnetic holding force.

How to Pack a shuttering magnet, to meet with your requirement shipping by sea, by air/express, and by railway?
Your shuttering magnet will pack with a double-wall corrugated carton firstly and tight with a strong packing belt. Between cartons and shuttering magnet, between magnets, there is a high-quality foam plate to separate and protect products from scratch and damage.

1. By Sea, you have 2 packing options by sea.
1.1 Packing by Pallet
1.2 Packing by Strong Wooden Case. 
This option looks more formal and beautiful. But it is more expensive 35USD per Case than option 1.

2. What should you pay attention to when shipping shuttering magnet by air?
 By Air and Express such as FedEx, DHL, UPS, and TNT:
In international air/Express transportation, magnetic items are sensitive, and their magnetism will interfere with the safety of aircraft transportation. Therefore, the airline decided that all items containing magnetism need to be magnetically inspected.
So we need to magnetically shield the items so that the magnetism of the items meets airline standards. So packing needs to insert thick iron sheets or iron boxes between the foam and carton wall.
Friendly tips:
When magnetic items are shipped together with non-magnetic items, all items must be checked for magnetism.
The magnetic inspection report is a one-time report and is only used once. Next time, even if you use the same logistics channels for the same items, you still need to do a magnetic inspection and obtain the corresponding magnetic inspection report. Except for FedEx and DHL, they accept annual magnetic reports.
By Railway, we use the same packing standard to that of by air.

How to use the Shuttering Magnet:
It is very easy to use this product. Simply move the concrete magnet onto the precast concrete platform (or tray) and press the button.

Open the magnetic field: 
Press the button by foot or rubber hammer.

Close the magnetic field:
Pry up the button by the lift lever (also known as the crowbar), the button can easy to be pulled up.

Shuttering magnets is a new step forward in the industrial production of the precast concrete structures. The magnets have been using in such production not so long ago. Initially, just the ordinary magnets were used to fix a formwork to the steel table. However, such an approach requires enormous mechanical forces. Moreover, in such case the magnets lose their shape and break down fast and, in addition, it damages the tops of the high-cost formwork tables.

Shuttering magnets is a design solution for the production of the precast concrete structures
The shuttering magnet in the magnet formwork have been applied to simplify a production process. They allow saving production time, cost and forces. Their functioning principle is rather simple and these are what you need for:

Steel table
Shuttering magnets
Magnet adapter
Shuttering board
Steel table
The steel table usually is made of steel. It allows forming the concrete structures of any shape easily. Some steel tables can be additionally equipped with a concrete densifier, a rotation gear, and the hydraulic systems.

Functioning principle of the shuttering magnets
To use the shuttering magnet you should set a magnet at the required place on the table and push the button above. When the button is pushed a magnet starts performing and get firmly fixed on the steel table. The adapters are used to fix a shuttering board to a shuttering magnet.

Shuttering magnet adapters
The adaptor for the magnets is an appliance with the space for shuttering magnets and shuttering board fixing. Some shuttering magnets are equipped with the adaptors, the rest are used in the system.

Shuttering board
There are two types of the shuttering board – a flexible board and a hard one. A flexible board is used for forming of special (off-standard) shapes, bends. A hard shuttering board is the right choice for the production of the standard products.

Shuttering magnets types and specifics
The shuttering magnets differ by several parameters:

Capacity
Adapter availability
Adaptor fixation availability
A unique combination of magnetic properties and multi-use explain a distinctive position of this equipment. The number of industrial spheres where the magnetic systems are used is growing day by day, and the precast concrete production industry is not exclusion. The shuttering magnets and magnet formwork systems are the brand-new decision on the industrial market.
