When we set out to shuttering magnet manufacture, we were not about to go small. We have a team of in-house magnetists here at Magprecast who create these advanced magnet arrangements. The precast concrete magnet has an incredible magnetic field strength and suction force. The suction force is over 200 times its own weight. Through the interaction of the magnetically conductive materials, the arrangement of the magnetic lines of the individual magnets changes.

Usage

When the Precast concrete magnet is in use, the bottom of the magnet is firmly attached to the steel mold platform. (The magnet and the platform form a complete magnetic circuit closing system.) This circuit exhibits an ultra-strong holding force. The shuttering magnet will not budge, slip, or shift while in use, making it much safer and user-friendly.

Lifting the magnet to the platform

When the precast concrete magnet is not in use, there’s a gap between the magnet and the platform. The magnetic circuit is not saturated, and the holding force is reduced. This is the time to pry the shuttering magnets open with a tool and begin using it with the platform.

Instructions for safe use

To ensure your shuttering magnets can last through countless uses, be sure to treat them with care. Below are some tips on how you can help lengthen the lifespan of your shuttering magnet.

  1. Don’t exceed heat over 80 degrees celsius. (The magnet will not function properly when too hot)
  2. Don’t roughhouse with it. Don’t randomly toss it or throw it on a table.
  3. Regular magnet cleaning is essential to keep rust and corrosion at a minimum
  4. Don’t put any foreign matter on the surface of the adsorption die

Why should you be using shuttering magnets?

Shuttering magnets have entirely revamped the precast concrete industry, for the better! Check out some of the perks of using them below. We’ve come up with 20 reasons, but we think it’s safe to say the advantages of shuttering magnets are virtually endless.

  1. They’re convenient and 70% faster than traditional methods.
  2. No damage to your die table from drilling hundreds of holes. No welding is needed meaning your die table will last for much longer.
  3. Cut down on labor costs. Shuttering magnets provide a short recovery cost cycle.
  4. They are suitable for various forms of templates (plastic, steel, wood).
  5. The magnet provides unlimited use options and can always be customized to meet your requirements.
  6. Construction personnel no longer need to target various forms of different products. All that is required is a magnet to increase the height of the board and the steel workbench.
  7. Fixed side touch for use in a concrete factory
  8. Cost-effective solution for building components.
  9. Easy to use and convenient for disassembly, and assembly,
  10. It allows users to reuse formwork molds, saving money in the long run.
  11. It can be used in various manufacturing types, from single products to mass-produced concrete products on a steel table.
  12. Reduces template installation time.
  13. A shuttering magnet can be customized to suit various requirements.
  14. Very easy to operate. The magnet is easy to position accurately.
  15. It’s incredibly versatile; use it with wood or steel formwork.
  16. It has a powerful adhesion range. The magnet can endure 450 Kg up to 3100 Kg.
  17. Help maintain the formwork table. Never have to drill holes in the surface, avoid welding, and eliminate the need to bolt the formwork table. The finish will remain unscathed, making it last much longer.
  18. Use the same magnet for multiple purposes.
  19. Integrated threaded holes can be adapted to the template.
  20. Improve the yield rate and quality of the precast concrete wall.

Precautions

Much like anything else, there are some precautions to take when using our magnets. These are not only for your safety but to ensure the precast concrete magnet performs as it should.

1. The internal components of the neodymium magnet must be kept clean. Avoid debris entering the template magnet. If foreign material makes its way in, the magnetic force will be in jeopardy.

2. The maximum operating or storage temperature must be below 80 ° C. Higher temperatures may cause the template magnet to decrease or lose its magnetic force completely. The temperature of a standard curing furnace is below 60 ℃ so the magnet can enter directly. If the curing furnace’s temperature is higher than 80 ℃, remove the magnet before entering the curing furnace.

3. Keep the shuttering magnet away from electronic devices and unnecessary ferromagnetic metals. This includes mobile phones, tablets, smartwatches, laptops, and computers. Almost no magnetic force is felt outside the steel casing of the shuttering magnets, but the magnetic force inside is extremely strong.

Safety note* If someone wears a pacemaker, extra care should be taken because strong magnetic fields can damage electronic devices inside the pacemaker.

  1. To avoid pinching your hands, always handle with care. Stack the magnets gently, and always look out for your fingers and hands.

Why choose Magprecast?

We get it; there are plenty of other companies that manufacture shuttering magnets. We hold ourselves to a much higher standard of quality and care for our customers. So, why us? Read on to learn how we’re different from our competitors.

Top 10 reasons why you should trust Magprecast with your next shuttering magnet purchase.

  1. We offer a much more reliable pull performance. On average, our suctions are 5~20% better than other magnets on the market. The pulling force of our MAG-2100kg reaches more than 2200kg.

  1. We use a much smaller gap to prevent concrete from making its way inside of the shuttering magnet. When concrete seeps in, the magnets become shaky and unsafe.

  1. Magprecast rigorously controls production. Our magnets are made with small gaps, a more stable interior, and overall better raw materials.
  1. We use an anti-rust treatment to make sure our magnets last longer than our competitors. The surface of the magnet is galvanized to prevent rust
  1. Our high-quality spring helps protect the magnet in case it’s dropped. Our springs are made with durable Japanese alloy steel SWOSC-V. This particular spring has a lifespan of over 1,000 years, and we use an anti-corrosion treatment on it as well.

  1. We have a better screw assembly. No detail is too small for us here at Magprecast. Even the smallest elements on our magnets, like the screws, are made with the highest industry grade 12.9 metal, and the surface is treated with an anti-rust spray.

  1. Concrete is an abrasive substance. It can easily cause damage and corrosion to the shuttering magnet. To prevent it, we use anti-corrosion treatments on our magnet parts. We understand these magnets will undergo harsh working environments and are continually subjected to sharp materials and high temperatures. Without our anti-corrosion treatments, the magnets would have a significantly shorter lifespan.

  1. According to customer feedback, the magnet is easily damaged. If exposed to the outside, magprecast listens to the customer’s opinions and improves it carefully. In order to make our shuttering magnets more durable, we wrapped a layer of stainless steel on the surface of the magnet, which effectively protects the magnet and allows The life of the magnet to be longer.

  1. The shells of our magnets are blackened during a meticulous 9-step process that includes cleaning, degreasing, washing, pickling, blow-drying, and oiling.
  2. We have much shorter shipping times. We know how frustrating it can be to wait almost a month for a product to arrive in the mail. We have different shipping options here, and most products will be shipped out within 3 days of the order date. That’s lightning-fast compared to other companies that have an average 25-day wait.

Packaging

How we ship the magnets out to our customers is just as important to us as the manufacturing process. Magnets can be tricky; you may be surprised by how many rules and regulations courier companies have regarding shipping magnets. We use magnetic isolation packaging in all of our shipments. This unique packing has anti-collision foam, an iron plate, and cardboard not only to protect the products but adhere to the safety requirements of courier companies. Our products will never get rejected by the postal service. We also take the time to ensure our packages are waterproof.

To us, sending our customers a clean, intact, damage-free package is our way of saying thank you. We genuinely appreciate each and every purchase made at Magprecast, and for over a decade, we have not had any issues or complaints from our customers that they have received damaged or sub-par items from us.

Shopping with us shouldn’t be difficult. For some orders, we even offer same-day delivery. Contact us to learn more about how you can receive your precast concrete magnet today. Our goal is to make shopping for shuttering magnets simple, quick, and hassle-free.

Quality control

We hand-test each shuttering magnet before we allow it to go on the market. We do a series of QA inspections, including a magnetic force test, taking measurements, and making sure the magnet can withstand the proper amount of weight. All of these tests are done in-house by our team of engineers who fully understand the delicate nature of magnets. We will never ship a product that doesn’t pass our rigorous QA tests. That’s not how we operate here.

FAQ

Why does the fixed effect of shuttering magnets weaken over time?

This happens when there are foreign objects (such as concrete, iron filings, film, etc.) on the bottom of the product or misalignment of the magnet, it can’t properly attach to the platform. You won’t get the same holding force, and it can weaken the magnet over time.

How can I prevent damage to my magnet?

Try to be as gentle as possible. Yes, the magnets are tough and can withstand regular usage, but if they’re banged around or mistreated, they won’t perform at their absolute best.

The physical properties of the damaged NdFeB material inside the magnet are hard and brittle.

Therefore, the magnet should not be impacted or thrown around by external force. Nor can the two magnets be attracted to each other. If the magnet inside the product breaks and damages the body, the product cannot be used.

When will I receive my shuttering magnet?

Most orders will be shipped out within 3-5 days. We try to keep our inventory high to reduce waiting times. If you need a customized precast concrete magnet or a logo, contact us to learn more.

Will the magnet lose tension over time?

Every magnet will lose some tension over time. Magprecast uses high-quality magnets to ensure our loss rate is only 1% within the first 10 years of use.

Precast Concrete Shuttering Magnets

precast concrete magnet since 2010 and 9 years of export experience.

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.
Tip: use 2 pcs tools together when removing more than 1000KG, in case of the lever bending
