Neodymium Magnets for Medical Devices 20161223
NdFeB Neodymium Permanent Magnets for Medical Application

Look for Neodymium Magnet  for Medical Device:
We have a need for custom geometry NdFeB magnets to be used in medical device application. The permanent magnet will have a complex shape (not a simple cylinder or block).  They need to be plated on all surfaces with 10 micron thick gold.
We are wondering if you have experience making custom magnets. 

Neodymium Permanent Magnets Manufacturer China Rare Earth Magnet Limited:
 

We can customize magnets as per specifications and drawings you gave.
Is there any possibility that you can send us a drawing of the irregularly shape and also advice the quantity you need?

Custom Medical Magnets in Intravascular Catheter:
We are using this magnet in a medical device (intravascular catheter).  As I mentioned earlier, the outer surface must be plated with pure gold (10 micron), all surfaces must be plated in gold, not just the OD surfaces.  The surface quality needs to be very smooth and clean, as this device will be in contact with patients.

NdFeB Permanent Magnet  Manufacturer China Rare Earth Magnet Limited:
Many thanks for your drawing.
The magnets you designed is very difficult to produce, because neodymium magnets are very brittle.
Please allow us some more time to check if it is producible to us.

NdFeB Neodymium Magnets:
Thank you for responding to our inquiry. It is a high “value–added” component because of the extra effort needed to make these magnets with these tolerances and without chipping.
The result is worth it for us – we must have them!  We realize they will likely be more costly than standard-shaped magnets used in other applications.
We thank you for taking the time to consider this project carefully.

Look for Large Ring Magnets:


I would like to get quotes for the price of the following two types of N52 neodymium magnet.
Shape: Ring Magnets
Size: OD=***, ID=***, Length=***
Coating: nickel plated

Permanent Magnets  Manufacturer China Rare Earth Magnet Limited:
The ring magnet of ***inch outside diameter, *** inch inside diameter, and *** inch length size is too large, and the length is too long to produce and magnetize.
Normally, the limitation of the length for magnetization is less than 2 inch.
Please could you revise the dimension of this ring magnet? 

Shortened the Length:
So would an OD of 5.22 still be too large if we shortened the length to 2 inches? If it is not too big could you quote the attached magnets?
Material: N52 Permanent Magnet

Neodymium Magnet Manufacturer China Rare Earth Magnet Limited:
If OD 5.2 inches are too large for production, we will quote based on the available closest size.
Our production team confirms these 2 large neodymium ring magnets  can be manufactured.
However, the cost of magnet is expensive because of high tooling cost and small quantity.

The First Neodymium Magnet Controlled Mechanical Pencil 20161206

The First Neodymium Magnet Controlled Mechanical Pencil 20161206
Neodymium Permanent Magnet Manufacturer China Rare Earth Magnet Limited

In modern society, mechanical pencil is the most common stationery in our daily life. The students always prefer to use the mechanical pencil to avoid the inconvenience of sharpening pencils. However, to our surprise, the ordinary mechanical pencil also has new designs with amazing technology. Recently, there is a new style of mechanical pencil in Kickstarter named Magno. This is the first permanent magnet  controlled mechanical pencil in the world that any other pencil cannot compare with it. 


The shell of the pencil is made of aircraft grade aluminium with anodised surface. There is a premium neodymium magnet  inside to hold the 2mm replaceable HB lead. Then the outer sleeve made by laser engraved mild steel controls the permanent magnet that once the sleeve moves, the neodymium NdFeB magnet and lead will move too, thus to decide the length of the lead when you write. However, as soon as the brass tip in the end tightens up, the out sleeve cannot move any more so that to write smoothly. In addition, there are four colors for users in case of drawing, including arctic frost, champagne gold, slate grey and strawberry gold. And there are also a mini sharpener and replaceable leads provided with every purchase.



From above all, we can found the details have been considered perfectly by the designer to offer a product with the best quality and highest level to the customer. What’s more, when it was produced, the designer said that this mechanical pencil can service for a lifelong time with super strong durability. The research team also showed that they tried to make not only a pencil, but also an artwork with excellent aesthetic. It is predicted that the product will enter into the market in December this year with the price of 20 Euros.

Neodymium Magnets for Seatbelt Buckle 20161203

Neodymium Magnets for Seatbelt Buckle 20161203
Custom Permanent Magnet Manufacturer China Rare Earth Magnet Limited

Questions on Neodymium Block Magnets:
Reference to the block magnets, I was wondering if below are possible

---Drill a hole in the centre of the magnet enough for a screw to pass through.
---Fabricate a magnet carrier/holder so it will stick much better on the seatbelt buckle.

Neodymium Magnet  Manufacturer China Rare Earth Magnet Limited:
Yes, your ideas are possible.
Please kindly send us engineering drawings of hole on magnets or magnetic holders so that we can do a further analysis.

Usage of NdFeB Permanent Magnet  on Seatbelt Buckle:
I don’t have any drawings for now. These are rough ideas only. Just to give you an idea how we are using your magnets, refer below:

The magnet is used to activate our sensor when the seatbelt is fastened.
We glue the magnet on the seatbelt buckle/metal.
The problem is, after some time the magnet falls off even with super glue applied.
We were thinking of having a hole in the magnet and drilling a hole in the seatbelt buckle/metal and insert a screw and nut to hold it. But this idea takes time to do.
We are also thinking of a magnet carrier that can hold the magnet in the buckle. Maybe your engineers have some ideas?

NdFeB Permanent Magnet Manufacturer  China Rare Earth Magnet Limited:
Our engineers suggest machine a groove suitable for the magnet in the seatbelt buckle and then put the magnet with super glue into the groove.
This may keep the magnets from falling off from the buckle.

Drilling a Hole in the Magnet:
Thank you for the suggestions though we cannot do it since the vehicles are not ours.
I was thinking again of drilling a hole in the magnet so it can create more traction on the seatbelt buckle once glue is applied.


Or like this:


Can you pass this idea to the engineers? Maybe they can comment on it.

Neodymium Permanent Magnets Manufacturer China Rare Earth Magnet Limited:
Our engineers reply that magnets in the drawings below are too difficult to produce due to the ellipse holes.
Drilling such holes is very time-consuming and high-cost and the drawing on the right is even impossible to produce.
But we can produce magnets with countersunk holes as the second picture. Commonly, magnets with such holes should be fixed by screws.
Also, our engineers do not think that grip will be increased with such holes. 
They recommend a kind of adhesive, CEMEDINE AB adhesive to attach the magnets on the metal buckle.
Maybe you can have a try.

The New Design for Safer and Easier Riding – Neodymium Permanent Magnet Pedals 20161130

The New Design for Safer and Easier Riding – Neodymium Permanent Magnet Pedals 20161130
Custom Neodymium Block Magnets for Bike Pedals

Generally, the most annoying condition for the rider probably is the foot slip off the bike pedal when cycling thus to take a missed step and lose control. Fortunately, a new design on Kickstarter named Vault MagLock may solve this problem smoothly with permanent magnets in the pedal to attach the shoes.

According to the introduction, the product is made of a lightweight plastic composite. And thanks to the neodymium block magnets  in the pedal, which works combined with a stain plate in the biking shoes, it makes riding easier for various cyclists. The inventor shows that with the neodymium permanent magnet, the rider just need to step on the pedal and then the foot will just like being locked on it thus will not miss any step anymore. It is said that the idea is not new actually and can dated back to 1896; however, it has improved greatly nowadays. For example, the magnetism of the pedal can be adjusted by riders’ requirements: the green hands can use minimum force; and the experienced can turn the force to 25 or even 30lbs.


Now, the Vault MagLock is available on Kickstarter for pre-order at a price of $80 a pair. And it is predicted that the goods will be shipped out in May 2017.


China Rare Earth Magnet Limited can customize neodymium block permanent magnets for bike pedals, and other magnets or magnetic assembly for other applications.

An English Research Team has developed the Smallest Charger with Neodymium Permanent Magnets in the world

Recently, an English research team Design on Impulse has developed the smallest charger in the world, named Nipper. It is actually a mini-charger that used in emergency with a 17x17mm size and a woven belt.

Usually, the permanent magnetic charger can be put into pocket or hang with the key. And when you need it, what you should do is just to open it and install two batteries. So how about the charging efficiency? After a series of experiments with a smart phone, the research team found that there will be 10% power when charging for 30 minutes, and 20% for 60 minutes, which can keep 3.6 hours in using condition or 4 days in standby mode. According the introduction, there is a Boost convertor in it to transfer the electric power of dry cell into 5V voltage for charging. And the core component of it is 3 neodymium magnets  to fix the batteries and conduct electricity, thus to omit excess parts for connecting, which is not only simplify the inner structure and the whole production process, but also save the total cost.


It can be predicted that with the more and more advanced science and technology, there will be a great prospects of neodymium permanent magnets in the future.

Neodymium Countersunk Magnets 20161104

Neodymium Countersunk Magnets 20161104
Custom NdFeB Permanent Magnets Manufacturer China Rare Earth Magnet Limited

Neodymium countersunk magnets are widely used in home decoration, family fitment and engineering construction industry. For example, NdFeB countersink permanent magnets  are more and more used in hinge system of cabinet doors and washroom door. Hinge is a kind of machinery used to connect two solid parts and allows rotating between both parts. It is formed by movable components, or folding material.
Hinges occupy an important position in hardware. The quality of hinge is directly related to the quality of the furniture and the use of the door.

For the doors in sitting room and bed room, the built-in magnets in hinges work in relatively dry environment. While for the doors in kitchen, balcony and especially bathroom, the neodymium permanent magnets in the hinges are likely to go rusting easily without superior coating protection. The rusty magnet cannot work well, and affect the function of other related parts as well. In moist environments, black epoxy coating is better than Ni-Cu-Ni in preventing magnets from corrosion and oxidation.
Customers and users can also choose better composite coating like Zn+black epoxy or Ni-Cu-Ni+Black epoxy.

We customized a variety of NdFeB Countersunk magnets for our customers.
Common countersink neodymium magnets  are listed as follows.
•    Rectangle/ disc/ arc shaped magnets with middle countersink hole
•    Magnet with single middle countersink hole
•    Magnet with double-edged countersink hole
•    Permanent magnets with 2 or more countersink holes on the same side

Sintered Neodymium Magnet VS Bonded Magnets 20160217

The Performance & Price Comparison of Sintered Neodymium and Bonded Neodymium Magnet 

Sintered NdFeB and Bonded NdFeB are two hot-selling powerful rare earth magnets in the industry. China Rare Earth Magnet Limited would like to share some information on the performance and price comparison of these 2 types of magnets.

The price difference of Sintered and Bonded neodymium iron boron is big. The cost of bonded permanent magnet material is much cheaper and the manufacturing process is relatively simple.

We have mastered the manufacturing technology completely. A lot of overseas enterprises can only be shut down as they are unable to compete with China's manufacturers.

Sintered neodymium magnet is anisotropic magnet produced by powder sintering. Normally, neodymium material can only be produced to a blank after sintering process. And then they can be produced into various shaped magnets after machining like wire-electrode cutting, slicing, and grinding and so on. Sintered neodymium rare earth magnet is difficult machining brittle material. The processing loss is big, the cost is high, dimensional accuracy is not good and corrosion resistance is poor. Surface treatment is needed. However, its advantage is superior magnetic performance like top grade N52 permanent magnet, N50M.

The market of Bonded NdFeB magnets started relatively late, but the market is growing rapidly. Relative to the sintered magnet, bonded magnets have obvious advantages on the dimensional precision, production cost and stability. Along with the miniaturization and micromation development of the electronic device, its application field will continue to be expanded. Steady growth in market demand and the cancelling of magnet powder patent make the imaginary space huge. Stable growth of hard drive market and the increasing penetration of automobile micro motor market and mobile phone vibration motor market guarantee the rapid demand growth of bonded neodymium magnet market. MQ magnetic powder patents expire and anisotropic bonded NdFeB magnets, etc. new technology constantly emerging establish a solid basis for the future development of bonded neodymium permanent magnets .

Analysis on the development trend of China NdFeB magnet in 2015-2020

The development direction of the neodymium iron boron magnet technology 
China introduced relevant policies to vigorously promote the development of the neodymium industry. It is expected that in the next few years the Ministry of science and technology will allocate funds with a total of RMB 3.5 hundred million to support the utilization of rare earth resources for wind power, electric vehicles, energy saving appliances, magnetic levitation train and other fields. The introduction of such national policies is undoubtedly the most powerful support of the future development of rare earth permanent magnet industry.

Analysis of neodymium iron boron magnet industry development trend
In recent years, given the further improvement of the comprehensive performance of the NdFeB permanent magnet, the NdFeB magnet has gradually replaced other magnetic materials and become the mainstream material of the market. Due to its high efficiency, energy saving, light weight, small size and other characteristics, the neodymium magnet has been widely used in wind power generation, new energy vehicles, energy saving appliances and other promising industries. With the increasing emphasis in energy saving and environmental protection, Neo magnet is facing numerous new development opportunities.

Prediction of neodymium iron boron magnet market competition pattern
With the rapid development of modern industry, the magnet has become an indispensable material of the modern industrial field. Strong magnet is a traditional sunrise industry in China, industry output value of which is now nearly RMB 3 billion, and is still increasing rapidly. As a branch of the strong magnet industry, the new functional neodymium permanent magnet material industry is in the high-end field of the industry, which has a promising market as a fast developing new entrant in recent years. Industrial strong magnet is the most mature product among new functional magnetic materials, which has become the preferred material for the underground interior landscape design, and expanded rapidly in the field of China magnetic levitation train, synchronizing the pace of the construction of maglev train. Given the demands from underground transportation facilities construction, such as urban tunnels, and underground pedestrian tunnels, etc, it is believed that the demands of industrial strong magnets will see a stable and quick growth in the future.

Bonded Neodymium Iron Boron 

Bonded magnets appeared in 1970s, when the SmCo was already commercialized. Market condition of sintered permanent magnet is vigorous, but due to the difficulty of precision machining it into a special shape, and issues of cracking, corner and edge breakage, and problems in assembling, its application is limited. To solve the above problems, China manufacturers crashed the magnet, mixed it with plastic, and pressed it in magnetic field, which is probably the original manufacturing method of bonded magnet. Bonded NdFeB magnets have been widely applied for its various advantages, such as, low cost, high dimensional accuracy, high flexibility of shapes, good mechanical strength, light weight and so on, annual growth rate of which is up to 35% now. Since the appearance of NdFeB magnetic powder, the flexible bonded magnets have developed rapidly because of the high magnetic properties.

Advantages: high remanence, high coercivity and high energy product, high performance price ratio, high flexibility in size and minimum dimensions.

Sintered Neodymium Iron Boron

Based on the strength of magnetism and the coercivity, sintered neodymium permanent magnet material is decided into low coercive force N, middle coercivity M, high coercivity H, super high coercive force SH, ultra high coercivity UH, extra high coercive force EH, all together six types.
Production of sintered neodymium iron boron magnets is started with a powder metallurgy process. Smelted alloy will be made into powder and then pressed in magnetic field into blanks. Pressed blanks will be densified in inert gas or vacuum sintering. Last, in order to improve the coercivity of the magnet, aging heat treatment will usually be applied by China factories.

Sintered neodymium magnet material, with its excellent magnetic properties, are widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields. Most common products include permanent magnet motors, speakers, magnetic separators, computer magnetic disk drives, magnetic resonance imaging equipment, etc.
