Photos Product … Magnets Manufacturer China Rare Earth Magnet Limited supplies flexible neodymium magnets. Anisotropic flexible NdFeB are the most powerful flexible magnets at present. We are capable of producing flexible permanent magnets whose magnetism performance meets the highest level in the world. Photos Product Features Dimension Range Flexible NdFeB Magnets VS Bonded NdFeB Magnets VS Sintered NdFeB Magnets Manufacturing Technology Application Features* In laboratory, the maximum magnetic energy of isotropic flexible NdFeB magnet is 80KJ/m3 (10.0 MGO) and that of anisotropic flexible neodymium magnet is 100KJ/m3 (12.5MGO). For mass production, the magnetic energy range of isotropic ones is 16~68KJ/m3 (2.0-8.5MGO), and can be magnetized in multiples. * Good flexibility can be installed automatically, more effective than mould pressing magnet ring; * No need of complex mould, short production cycle; * Applicable temperature range: - 40 ℃ ~ 120 ℃; * The products are approved by reliability test system, stable and reliable; * The product can be made in different shapes, like flexible permanent magnet strip, volume, ring, large thin sheet and so on. * The magnetic energy and the hardness can be customized according to customers’ special requirements.Dimension range for mass production（mm）Length: ~30000mm Width: ~300mm Thickness: 0.4-6.0mmWhat's the difference between flexible NdFeB magnets, bonded NdFeB magnets and sintered NdFeB magnets?Flexible neodymium magnet is a kind of bonded NdFeB magnets. According to the forming modes, it can be divided into three types like mould pressing, injection and calender. Flexible NdFeB belongs to the type of calender.Bonded NdFeB permanent magnets of the final size can be obtained without mechanical processing and save material, with high dimensional accuracy, suitable for mass production. In addition, corrosion resistance is better than sintered magnets. The disadvantage is that the magnetic performance is relatively low.Sintered neodymium magnets are anisotropic magnets produced by powder sintering process. Generally, sintered magnetic powders can only produce a blank after sintering processing, and then after mechanical processing (such as cutting, slicing, grinding, etc.) become various shapes of magnets. Sintered NdFeB belongs to difficult machinability of brittle materials, processing loss is big, processing cost is high, the dimensional accuracy is not good and corrosion resistance is poorer, so surface treatment is needed. But the advantage is the magnetic performance is as high as 52MGOe or more.Manufacturing TechnologyFlexible neodymium magnets are composite materials made of rubber as a binder, rapidly quenched NdFeB powder as filler, and auxiliary processing additives, with the production technology of composite rubber products.ApplicationFlexible neodymium permanent magnets are universally welcomed and applied in sensor, micro motor and some other fields like wheel key of mobile phone, wireless mouse, anti-theft products in supermarket, planar horn and more and more new applications are expanding.

If all the items are ordered, we usually give special discount. Reliable Permanent Magnet Manufacturer China Rare Earth Magnet Limited Some new clients like to bring new innovative products on the market and are looking for a reliable manufacturer. For new products, several clients just tell us the shape and size scope, holding force, and ask us the maximum holding force. For neodymium magnets D20x1mm, clients require minimum holding force 3kg, but it can’t reach even in top grade N52 NdFeB magnetic materials. If possible, we usually suggest our clients consider increasing the size to enlarge the holding strength. Or else, you can use a metal cup magnet to replace an individual magnet. The estimated holding force of a N52 magnet D20x1mm is around 1.5KGS. For thicker magnets in size D20x2mm, the holding force may achieve 3KGS. The actual holding force should be tested by the users. We usually suggest clients order samples in different sizes and make a testing at their side. View Details

Three self-solved methods for problems of ferrite magnetic speakers in cars. Speakers are the mostly used equipments in cars. It is inconvenient when the speakers are breakdown. Sometimes you honking the speakers, they sound like mosquito, very husky or even silent. Why will they be breakdown? According to my experience, troubles with speakers are always defects of themselves. Especially those devices are installed in some incorrect position. When it rains, the speakers are easily to be soaked, which damages it. There are always three reasons for the troubles of speakers---themselves, the switch contact and horn harness. When your speakers have some problems, you can refer to the steps as follow. 1. Sometime the speakers are silent. When you press switch of permanent magnet speakers, it sometimes blares, or it sometimes doesn’t. This is often because the contact points inside are poor or the speakers have problems themselves. 2. The speakers sound husky, always because of bad contact of the plugs. Especially, contact around the steering wheels will be often wearing out due to frequent use. 3. The speakers are entirely silent. First, you should check whether the fuse is molten, disconnect the plugs and use multi-meter to examine whether the contact is power on when you honk the horn. If it is power off, you should check ferrite magnetic horn harness and relay. Or if it is power on, the problems are caused by the speakers themselves. You can adjust the conditioning nut of the horn and check whether it will sound. You should replace it if it remains silent. View Details
