Mould Injection NdFeB
Injection Plastic NdFeB magnet is a kind of new generation composite material made from permanent magnetic powder and plastic. Injection NdFeB powder is blended with a plastic material and injection molded. With High precision of size, it can be made into complex shapes and also be bonded with other components. The injection molding magnet can be magnetized in any directions and with multiple poles.
Advantages of Injection NdFeB Magnet:
1. Design and manufacturing of orientation moulds were carried out.
2. Having high dimensional precision and impact-resistance. Capable of forming products with inlay.
3. The injection molding parts are suitable for forming products with various shapes and thin walls.
4. Multi polar magnetization can be carried out according to customers’ requirement.
Application Areas
Mould injection NdFeB have various application areas such as:
· Automobile Instrument Cluster
