We control every material to have stable 2-3 suppliers, who can get much of our orders, and offer stable quality and excellent service. And in our system, we have more than 1000 backup suppliers there, to meet any special and urgent requirement from clients.

1.2 Incoming material quality inspection and controlshutering magnet production equipments 1

Besides the neodymium magnets, we also have strict inspections of every incoming material (Dimensions, weight, material level, ductility, permeability, metallographic structure, fatigue test) such as the steel casing, button steel and plastic, the spring, fixing screws, and so on.

In order to improve our inspection strength and ability, we also have a great partnership with 5 3rd party inspection organizations, to do regular and irregular material analysis and inspection.

2. Excellent production equipment for the quality internal control of quality and lead time

Most competitors outsource the post-production processing to a small workshop, but the quality and process control is lacking an internal inspection. Even if they found the problem, it is difficult to improve and solve, and finally, clients are burdened with the loss. This is a serious current situation and problem for Made-in-China production.

Compared with other competitors, we have spared no effort to improve our self-production ratio and equipment-owned ratio since 3 years ago. We imported the automatic laser cutting bed from Europe, to improve precision-oriented and bending machines and so on. It can be said that apart from painting and baking, we have almost mastered all the processes and equipment for the production of shuttering magnets, which leads to better, stricter internal control than our competitors.

3. Pull Strength Testing:

Regarding the detection of suction, we will inspect all orders with less than 10 pcs; if the orders are higher than 10 pcs, our inspection ratio is 10%.

4. QM& QC System

How to Pack a Shuttering Magnet, to Meet Your Requirements Shipping by Sea, by Air/Express, and 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.

Shuttering Magnet Packaging By Sea

2. What Should You Pay Attention to When Shipping Shuttering, Agents 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.

Shuttering Magnet Magnetic isolation packaging by air

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 as 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.

Correct use of magnetic box

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.

Maintenance of Shuttering Magnets:

First, In the use of the shuttering magnet:

It should avoid any debris at the bottom of the table, affecting the magnetic force of the shuttering magnet too much and the mold table. We use high-performance rare earth permanent magnet materials to produce strong magnetic attraction in the magnetic circuit. When the shuttering magnet is in the working state, the suction surface at the bottom of the magnetic block is closely attached to the steel mold platform and is firmly held. However, when there is a foreign matter (such as concrete, grease, or film) at the bottom of the magnet block, it cannot be closely attached to the platform, and the attraction power will be significantly reduced.

To this end, we take the GME-1000 shuttering magnet as an example to research the relationship between the holding force and the bottom of the magnet block and the platform clearance. We placed 0~10 sheets of A4 paper (the thickness of each sheet is 0.09mm) between the bottom of the magnet block and the platform to test the adsorption force of the shuttering magnet under different gaps. The test data is as follows:

As can be seen from the above figure, the gap between the bottom of the magnet block and the platform will significantly affect the holding capacity of the shuttering magnet, so we recommend that the customer maintain the shuttering magnet as follows:

Secondly, clean the debris on the bottom and the debris on the table:

Before using the shuttering magnet, make sure the bottom of the magnetic block and the platform are clean and flat. If there is a foreign matter at the bottom of the shuttering magnet, it can be cleaned with a stainless steel scraper (the iron scraper will be absorbed and cannot be cleaned). If there is concrete, it is difficult to clean the material. At the time, it can be cleaned with a polishing knife. As shown in the figure below, the wire polishing plate is installed on the sander to polish the bottom of the magnet block.

We cleaned it with a pneumatic air gun if you have one.

clean the debris on the bottom and the debris on the table

Third, gently take care to prevent damage to the magnet inside and the shuttering magnet:

As the high-performance permanent magnet material used is sintered by rare earth materials, it is hard and brittle, and it is easy to be broken, similar to ceramics, Therefore, during the use of the shuttering magnet, it should be prevented from falling and chaos, and it cannot be thrown at a long distance after it removes from the mold. Avoid using a hard tool (such as an iron big hammer) to knock, bump, etc., causing the shuttering magnet to deform. As shown below:

Rude discard shuttering magnet lead to deformation

Fourth, the shuttering magnet collection:

After the sshuttering magnet collectionhuttering magnet is used, the shuttering magnet should be cleaned and placed on the stainless steel cart to keep the shuttering magnet clean for convenient use. The shuttering magnet should not be placed on the iron cart to avoid it being caught and cannot move away.

Fifth, shuttering magnet storage:

1. When the shuttering magnet is not used for a long time, after the shuttering magnet is cleaned, apply anti-rust oil (such as Mobil, Great Wall, etc.) at the bottom of the shuttering magnet to prevent the magnet block from rusting and affect the holding power.

2. The ambient temperature of the shuttering magnet used and stored should be no higher than 80 °C, and there is no corrosive medium such as strong acid or alkali. In summary, as long as the above protection, cleaning, and prevention of knocking, etc., I believe that the shuttering magnet of Great Magtech (Xiamen) Electric Co., Ltd. will be durable and trustworthy!
