If magnetize the magnets across outer diameter, the magnetic force focus on outer circumferential surfaceInstead to magnetize across inner diameter, the magnetic force is concentrated in the inner circular surface. The price is the same, but the use effect is different. Please reference the sketch of magnetization across inner diameter and across outer diameter belowThe direction of arrow is magnetization direction, please check. Magnetized through Inside Diameter or Outside Diameter:We don’t understand the difference between the “inside diameter” vs “outside diameter” magnetization. If the ring is radially magnetized, the magnetic moment should go from the center to the outside like your drawings show. Basically, the magnetization is axially symmetric. Could you please explain in more detail the difference?Multi-pole Permanent Magnets Manufacturer China Rare Earth Magnet Limited:In brief, the choice of magnetization direction basically depends on the magnetic application of your products.Along which magnetization direction, the performance is the highest.Which side or surface of the magnets do you mainly want to use please? The outer circular surface or the inner circular surface or the flat surfaceTo magnetize through outer diameter to inner diameter, the magnetic performance on outer circular surface is the highest.To magnetize from inner diameter to outer, the magnetism on inner circular surface is the highest.Multi-poles Outer Diameter Magnetization:Okay. I think I understand. You are asking where to place the magnetization fixture...For magnetic fields strength, outside is better. However, I want to be sure that the outside of the ring has a nice sinusoidal transition between poles.8 Poles NdFeB Magnets Manufacturer China Rare Earth Magnet Limited:We noted it. The magnetization orientation you desired is 8 poles through outer diameter. For your request of sine wave, our engineering said the outer diameter is large and the pole width is too big, sine wave is not likely to meet. Anyway, our engineering will try to make the bonded permanent magnets in this direction. View Details

Raw Materials Preparation and PreprocessingIt is to do some preprocessing like weigh, smash, rust cleaning to the raw materials. Processing Equipment: Steel bar Shearing Machine/Tumbling Machine2. Smelting of Neodymium Permanent MagnetCompound the preprocessing materials of praseodymium neodymium, pure iron and Ferro-boron in certain proportion, and make high-temperature melting in vacuum melting furnace with argon protection. After that, make melt-spinning to achieve homogeneous composition and great degree of orientation. Processing Equipment: Vacuum Melting Furnace3. Hydrogen ExplosionAs the hydrogen absorption character among rare earths, the neodymium alloy will expand and crack in hydrogen, which makes neodymium have a loose structure. The process not only improves powdering efficiency, but also lowering cost greatly.Processing Equipment: Vacuum Hydrogen-treated Furnace4. Powdering ProcessWithout any pollution and any abrasion to the machine, powdering process is to make high velocity impact for the materials themselves by Airflow Grinder, which is efficient and convenient.Processing Equipment: Airflow Grinder5. Molding and OrientationMolding is to make the powder a fixed size and shape, and orientation is to determine a magnetized direction for the disorder powders. Commonly, the magnetic field pressing machine and isostatic pressing machine and used in this process, while for the special shaped NdFeB permanent magnets, it is necessary to use mold to shaping directly.Processing Equipment: Magnetic Field Pressing Machine/ Isostatic Pressing Machine6. Sintering Having a series of physical and chemical changes of the materials in high temperature, sintering is the last step of forming process, which is vital to the density and micro-structure of neodymium magnets. Processing Equipment: Vacuum Sintering Furnace7. Machining The neodymium magnets after sintering are just workblank, and the further machining is necessary to achieve an accurate dimensions and shape. Generally, there are two ways of machining: Grinding and Cutting.Processing Equipment: Flat Grinder/Paralled Surface Grinding Machine/Chamfering Machine8. Surface TreatmentSurface treatment like Ni, Zn, NiCuNi, phosphate and so on, are necessary to achieve a good appearance and corrosion resistance. 9. OQC and Packaging Before packaging, the permanent magnet manufacturer should do a series of inspection, such as high temperature test, salt spray test, etc. to ensure the magnets meet requirements.

I would want something that is … NdFeB Magnet Coatings 20170214NdFeB Permanent Magnets Bonding to Stainless Steel BaseplateLook for Durable Coating of N52 NdFeB Magnets NdFeB Magnets</a>: What kind of protective coatings can I get on the N52 permanent magnet disc from you? An epoxy...? I would want something that is pretty durable.What colors would be available (if any)?Would it be possible to get them coated and leave the south side uncoated for bonding? (Just coat the north side and the edges). I don't care which side is uncoated if that matters. Or, would your coating all around the magnet impact the bonding of your magnet to another metal surface?Neodymium Permanent Magnet Manufacturer China Rare Earth Magnet Limited:We can provide various kinds of coating according to customers' requirement, including epoxy. Color of coating are often silver (NiCuNi or Zinc) or black (epoxy).Commonly, coating all around has little impact when bonding magnets to another metal surface.However, may I know what you will use to bond magnets to another metal surface, Loctite glue or something else?By the way, do they work in humid environment or some kind of extreme environment? Environment also has great influence on choosing coating. Working Environment of the NdFeB Magnets: I use Loctite AA 331 magnet bonder with Loctite SF 7387 ActivatorThe environment is not harsh at all. They'll be used in the construction and homeowner industries. I have had one in my pocket for over 7 years. I started with a zinc coated one, and the zinc wore off over time.The non-protected magnet I carried in my pocket wore and chipped the edges. I tried a ceramic coating on them, but it was too hard and not durable.When I switch to your epoxy coated magnets, they will be bonded to a stainless steel baseplate. No further coatings on them.NdFeB Permanent Magnets Manufacturer China Rare Earth Magnet Limited:I got reply from our technicians and they confirm that black epoxy coating is very durable and has very strong resistance to corrosion.Black epoxy will not have influence when you glue the magnets on stainless steel.In addition, we can offer you free samples.
