The product can be customed by your requirement.
Compression molded magnets are made by first mixing the magnetic powder with the polymer binder and then by compressing the mixture in a press mold. These magnets exhibit a higher level of performance than the injection molded couterparts due to higher density.
Compression molded magnets assembled with shaft, yoke and other parts.
Features of compression molded magnets
Highest level of magnetic performance among Nd-Fe-B isotropic bonded magnets.
Since these are isotropic in nature, any magnetization patterns can be used. This is especially advantageous to multi-pole magnetization.
Thin wall thickness (minimum 0.3 mm) can be produced. Inductor Injection Molding Nd Magnet for Embedded Permanent Magnet Synchronous
Excellent corrosion resistance is realized by Daido original coating technology.
Bonded NdFeB magnets are usually made of NdFeB alloy powder mixed with epoxy resin and pressed. They can also be mixed with plastics and molded by injection or extrusion. It has the following characteristics:
1. High magnetic properties: the magnetic properties are between sintered NdFeB magnets and ferrite magnets, with better consistency and stability.
2. High dimensional accuracy, large degree of freedom: product shape and size are determined by the mold. It can be made into ring, tile, block and other free shapes without sintering and post machining.
3. Good corrosion resistance: after surface coating or some special treatment, it can be used in daily or bad environment for a long time.
4. There are various ways of magnetization: the pole can be charged into multipole, oblique pole, end face magnetization, etc., and the waveform can be square wave and sine wave.
5. Injection magnet is more suitable for integral forming of magnetic components, suitable for mass production and high production efficiency. DC Motor Bonded NdFeB Tile Arc Magnets for Household Appliances
