Introduction of injection molding magnetic products;
Injection molding is the composite granulation of magnetic powder and thermoplastic (PA6,PA12,PPS) by Injection molding. Through this process, the magnet is integrated with the core, axis, or other parts of the motor, saving the complex assembly process. In addition to the common iron oxide, there are rare earth injection magnetic magnets that combine with the MQ ndfeb magnetic powder with better magnetic performance. In addition, injection molding magnets will have different temperature tolerance depending on the adhesive used. The temperature tolerance of PPS products can be up to 235℃.
Injection magnetic characteristics;
1. The injection magnetic magnet can be designed with thin wall and abnormal shape, and the magnetic field can be designed with axial, radial or multi-pole magnetic field and compound magnetic field.
2. In the process of injection molding, the iron core, axis or other parts of the motor can be directly put into the integral molding, saving the subsequent assembly cost or complex assembly process.
3. Injection magnet has high precision, good consistency and stable performance, which is widely used in automatic equipment, stepper motor, air conditioner, self-dynamometer, instrument, brushless motor and high-end electrical appliances.
