Delivery time: 10-20 days, depending on the processing difficulty The magnetic pole observation plate can quickly detect the number of magnetized poles of the magnetIdentification method for magnetic pole observation film: Test the magnetization level of the magnet: Place the magnet product in the developing area of the magnetic film to clearly see the magnetization level of the magnet product. The magnetization levels of the magnet product are all even, as they are one-on-one.The magnetization method for identifying magnets: The magnetization methods for magnet products are commonly axial magnetization and radial magnetization. Axial magnetization products can be seen on the height plane of the magnet, which divides the height (i.e. thickness) of the magnet into two halves, showing a cross shaped boundary. Radial magnetization does not exist, while radial magnetization products are evenly divided into several parts, one vertical and the other vertical.Identification of strong and weak magnetic surfaces: For multi-stage magnetized products, the magne: 16

Large and small head magnets Neodymium iron boron large and small head strong magnets can be understood as two circular magnets with different diameters sticking together, represented by the thickness of the large diameter D1 * and the small diameter D2 *. Some customers also refer to them as step magnets or circular convex magnets.A magnet with a diameter of D5 * 1.8+d4 * 1.9mm represents a diameter of 5mm with a thickness of 1.8mm for the large end, and a diameter of 4mm with a thickness of 1.9mm for the small end.What is the function of a large and small head magnet?Like some slotted magnets, they are mainly used for positioning or special requirements.Where are the large and small end magnets mainly used?Electronic products, connectors, cigarette lightersIntroduction to the Parameters of Large and Small Head MagnetsShape: Large and small head magnets, diameter and thickness can be manufactured according to your requirements.Material: N35-N52, or high-temperature resistant material.Plating: Galvanized/nickel pl: 16

Do you know the drawbacks of ferrite magnets 1. Magnetic force difference. This is the biggest drawback of ferrite, and most of the reason for not choosing it is because its magnetism does not meet the requirements.2. Large volume. Weak magnetic force naturally requires a larger volume, as many high-tech products such as smartphones and robots currently use neodymium iron boron with small volume and strong magnetic force.3. Poor tolerance control. The tolerance of ferrite magnets is usually greater than that of neodymium iron boron, and of course, ferrite can also be precision machined. The magnetic ring can be ground internally and externally, but the cost is relatively high.4. It is not easy to process into complex and irregular magnetic shapes. This is also the main reason why most ferrite magnets we see are circular and square.Oh, so there are so many drawbacks to ferrite magnets, do you know all of them?: 16

The magnetization method of injection molded magnets Injection molded magnets can be magnetized in various ways, such as inner and outer filling with radial multipole, axial multipole, single sided multipole, etc.Production process of injection molded magnets:During the molding process, the material is completely filled into the mold cavity at the highest concentration under strong injection pressure, and in addition, the material contains thermoplastic adhesives, resulting in good physical and mechanical properties of the magnet.Mainly based on temperature characteristics, strength, water absorption, solvent resistance, complexity of magnet shape, and compatibility with magnetic powder.Temperature characteristics: The maximum operating temperature of injection molded magnets depends on the magnetic powder and binder used. For example, the combination of ferrite powder with nylon 6 or PPS can pass the test at 180 ℃. Nylon 12 melts at temperatures above 170 ℃, so if the designed temperature of the magnet exceeds 150 ℃, nylon 12 is not rec: 16

The purchased magnet has broken a lot Magnetic rings are easy to break, and this issue has always been a concern in the magnet industry. Magnetic rings are inherently fragile products, so how can we avoid this problem and why magnetic rings are so easy to break? The following magnet manufacturers will share their experience over the years with you.Strong magnets are inherently fragile because the materials they use are all rare earths, and these materials are easily broken no matter where they are used. However, if they are not made of these rare earth materials, they are equivalent to products, becoming waste, lacking characteristics, ineffective, and useless. So we should try our best to avoid it being broken, especially during production, we must handle it with care.Is there a magnet that won't break? It is also impossible to achieve something that is not broken, and we can only try to avoid it and do it better.In terms of packaging, workers also need to pay special attention, handle with care, and add foam to shock: 16

The main application fields and performance characteristics of soft magnetic ferrite Soft magnetic ferrite is a ferrous magnetic oxide mainly composed of Fe2O3, produced by powder metallurgy method. It mainly includes several types such as Mn-Zn, Cu-Zn, Ni-Zn, etc. Among them, Mn-Zn ferrite has the highest production and usage, and its resistivity is low, ranging from 1 to 10 ohms/meter, generally used at frequencies below 100kHz. The resistivity of Cu Zn and Ni Zn ferrites ranges from 102 to 104 ohms per meter, with low losses in the radio frequency range of 100kHz to 10 MHz. They are commonly used in radio antenna coils and radio intermediate frequency transformers.At present, ferrite soft magnets in China are mainly used in the fields of communication, home appliances, and new energy. In the future, soft magnetic materials will be mainly applied in new infrastructure markets such as high-end consumer and industrial electronics, new energy, cloud computing, Internet of Things, 4G and 5G communication, power supply devices, and new consumer electronics.: 12
