Compared with traditional … Ferrite Permanent Magnets 20161222Factors of High-performance Dry-press Anisotropic Ferrite MagnetsGenerally, the performance of dry-press anisotropic ferrite magnets mostly depends on the quality of raw powder and the relevant magnetic field molding technology. Compared with the traditional wet-pressing process, there are additional two procedures of dry-pressing, namely, drying and dispersing, which are also the key processes of manufacturing. Below are some other specific factors of dry-pressing anisotropic ferrite. Raw Materials and Recipes Commonly, the raw materials and recipes of high-performance dry-pressing anisotropic ferrite permanent magnets are similar with the wet-pressing products, which can be used to make dry-pressed powder directly. Before making, Physical and Chemical Analysis should be carried on the raw materials Fe2O3 and SrCO3, and then adjust proportioning properly according to the amount of intrinsic contaminant. Manufacturing of Dry-pressed PowderAs is well-known, the most important technical parameter of permanent ferrite magnets is Br. In order to improve Br, it is necessary to achieve high density and orientation degree with certain recipes. And as the lack of flowing media in the dry powder, it is relatively hard to reach high orientation degree. Thus, some organic additives, like camphor and calcium stearate, are added as binders and lubricants. On the other hand, it is also available to change the particle size distribution and the particle morphology. As proved, the sanding particles are easier to rotate and thus achieve higher orientation degree instead of ball-milling. Magnetic Field Molding TechnologyTo acquire high-performance dry-press anisotropic ferrite, a strong permanent magnet field is also necessary besides superior dry powder. To wet-press products, it requires higher magnetic field when the particles in the slurry is smaller. And to the dry-press, there are some large sample will crack in the molding and sintering process. And the main reason is the lack of flowing media that mentioned above. Thus, to adjust the adding mode and amounts of organic additives and to advance the sintering technology are good solutions for reduce cracking and improve magnetic field. All in all, ferrite magnets manufacturers can adjust these factors accordingly to achieve good properties of high-performance dry-press anisotropic ferrite.

Instead, … Radially Magnetized Neodymium Ring Magnets 20160929Permanent Magnetic Assembly Manufacturer China Rare Earth Magnet LimitedIn general, as the limitation of the dimensions and high cost of molds, the manufacturer always not produce radially magnetized ring permanent magnets directly. Instead, they often use fan-shaped arcs to splice together to achieve the same function. During the process of manufacturing, transporting and assembling, the magnetic rings may fall apart, so the manufacturer can install non-magnetic rings, such as aluminium or stainless steel, to fix the fan shape blocks. And these non-magnetic rings can be removed before assembly. Inquire Radially Magnetized Sintered Neodymium Ring Magnets : I would like to have a quotation for the permanent magnet ring. The material would be N50M neodymium magnet. We have 2 rings dimensions. Some of the magnets will be axially magnetized and the others will be radially magnetized, to the outside and to the inside. We would like to have at least 16 fan-shape blocks assembled glued together for each rings (especially for radially magnetized magnets)Magnetic Assembly Manufacturer China Rare Earth Magnet Limited:Could you please confirm can we use steel/iron ring to fix the fan shape blocks so they won't easily fall apart?Permanent Magnetic Assembly with Glue + non-magnetic external ring like aluminium or stainless steel:The magnet rings will be assembled together so we cannot have an external ring. At the end they will be inside an iron ring so I think they will not have any risk to fall apart. They only risk they fall apart is during the manufacturing, transport and assembly. If you want, you can install non-magnetic rings (aluminium or stainless steel, etc.) that we can remove just before the assembly.Neodymium Arc Magnets Manufacturer China Rare Earth Magnet Limited: Based on our experience, our technician team all agree with you that there will be big risk that the assembled/glued rings will easily fall apart. Is it acceptable that we supply you with arc segments and you can assemble them into the rings you need after receiving them?I attached the quotation based on arc segments.Assembly:I am sorry we will not be able to position and glue ourselves the arc segments. Would you be able to provide the assembled rings? Radially Magnetized Ring Magnets Manufacturer China Rare Earth Magnet Limited:Please check the attached quotation based on assembled rings, all assembled with 16 arc permanent magnet segments as requested. We will glue the rings and use metal rings to fix them. The metal rings will be removable. View Details

And the inner magnetic core includes cylinder magnets and magnetic iron sheet. The surface is stainless steel, which can protect the magnetic rod not damaged. China Rare Earth Magnet Limited can customize it as per clients’ requirements or drawings.Working environmental decides the magnetic rod should be corrosion resisting, high temperature resisting and strong magnetic flux destiny. The choices of different magnets result in different capacity of temperature resisting and magnetic flux destiny. If the magnetic flux destiny should up to 10000 gauss, the type of ∮25mm magnetic rod should use high performance neodymium permanent magnets. If the temperature exceeds 150 degree, then choose SmCo magnets. However, if the diameter is very big, we not choose SmCo for its high price.Magnetic rod mainly used for filtering metal filings, powders or liquids in the material. But the magnetism will be damaged when contact with the liquids. The common magnetic rod can use for 1 to 2 years in the condition of heavy load, and 7 to 8 years in the condition of light load. It is mainly apply for the field like Plastics, foodstuffs, environmental protection, filtering, chemical, electric power, building materials, building ceramics, pharmaceutical, powder, mine and coal.China Rare Earth Magnet Limited always customizes permanent magnets and magnetic assemblies, if you have such demand, welcome to contact us!

When we produced the samples for you, we made an easy and simple tooling for the sample production. In that way, we did not need to modify the existing mold we have for similar sizes, which save time and cost. The easy and simple tooling is not applicable for bulk production. So when the technicians checked and want to modify the mold today, they found that the existing mold has become bigger for these years.The magnet size has to be widened.Also, the tolerances of this kind of magnets will be ±2%.May I know if the size and tolerance are acceptable for you?Widen Sizes and Tolerance:That will be fine.
