Permanent magnet powder and polymer are first kneaded together to form a compound, which then can be used for injection molding. Injection molding of permanent magnets is basically identical with injection molding of normal plastics. The only difference is that for production of anisotropic magnets a magnetic field is needed in the molding tool. After molding the magnets normally do not need any further operations, except magnetising, before use. In certain cases magnets can be magnetized in the molding tool and separate magnetizing is thus not needed.
The Injection magnets can be processed into thin-walled ring, rods, slice and various special complex shapes (such as: steps, damping trough, holes, pins, and more
Injection plastic NdFeB magnet is a new type of composite material made of neodymium ferroboron magnetic powder, plastic (nylon, PPS, etc.) polymer material by special process.
Can be made into hybrid magnets, magnetic adjustment range of the widest. It can be axial single-pole magnetization, radial multi-stage magnetization and axial radial compound magnetization. The magnetic energy level of anisotropic injection of neodymium iron boron is as high as 15.3m, far higher than that of the same sex 7M, it not only has the high performance of pressing magnetic steel, but also has the high precision and strength of injection magnetic steel, so the market prospect is broad.
Shortcomings of injection ndfeb:
1、Injection molded magnets offer lower magnetic performance than the compression bonded magnets (due to lower magnetic loading)/Possible tooling charges for production and magnetising
2、For quotation or sample of magnet, please send us your drawings. Thank you.
What is Injection Moulding
Magnet material can be directly molded into, onto, or against other assembly components eliminating subsequent assembly steps. This is called insert injection molding. Custom Injection Molded Nd-Fe-B Magnets
Injection molded magnets are available by using ferrite, neodymium-iron-boron, or blends of magnetic materials to achieve an extensive range of properties. Binder materials include Nylon 6 and 12, PPS, and Polyamide. The binders and magnetic alloys are capable of a wide range of working temperatures from below -40°C to above 180°C. The Injection molding process allows the ability to produce very intricately shaped magnets with extremely tight tolerances and a wide variety of physical and magnetic characteristics. The finished parts can be either very simple or complex in geometry. Injection Plastic NdFeB Magnet for Rotor
The properties of injection molded magnets vary greatly, depending on the type of magnetic material and binder utilized. HSMAG has both Neodymium and Hard Ferrite injection molding capability, and it is also possible to utilize a blend of different magnetic material to produce the desired properties. Several types of binder can be employed depending on the application, and we offer a variety of nylon and PPS grades to suit the specific needs of our customers.
