Brief Int
Permanent Bonded NdFeB Magnet With Epoxy For Motors And Electronic Parts
Brief Introduction
Bonded NdFeB magnet is produced via the technique---a special form of NdFeB powder is blended with plastic carrier material, die pressed and then heated. They have lower energy than Sintered NdFeB. The bonded NdFeB are isotropic-i.e. they can be magnetized in any direction. According to the different processing methods, bonded NdFeB is divided into two types- Compression Moulding NdFeB and Injection Moulding NdFeB.Its use with temperature-resistant plastic enables good stability and coated with a special colophony for high rust-resistance. The Bonded NdFeB magnets are widely used in automobile, communication, computer, micro-motor, electronics and many other fields.

Main Features
Production Flow Chart for Injection Bonded NdFeB
Raw material (Mainly NdFeB powder and binder) preparation---Blending NdFeB powder and binder---Injection molding---Machining---Surface treatment---Magnetizing---Final inspection---Packing---Warehousing
Applications
1. The compression molding magnets, as for simple mould and high magnetic properties, are widely used in stepping motor, CD-ROM spindle motor, general motor, vibrating motor, pick-up, HDD spindle motor, and FDD spindle motor.
2. The injection molding magnets, as for complex mould, magnetic properties around 6 to 7 MGOe, and highly consistency, are widely used in electric expansion valve, air-condition motor etc.
