Injection molding magnet is characterized by not only unipolar magnetization in the axial direction, but also multi-stage magnetization in the radial direction, but also composite magnetization in the axial and radial direction. The product has smooth appearance, high dimensional accuracy, good consistency, no follow-up processing, stable performance, shock resistance and shock resistance. The product can be complicated. It is an indispensable signal source and constant magnet source for precision micro-motor and automation industry. It has advantages that other magnets can not replace and compare with.
The binder used for injection magnets is thermoplastic, and there are two types of binder in the market: nylon (PA) and polyphenylene sulfide (PPS). The most widely used nylon variety in the industry is PA12, which has less water absorption and better mechanical properties. PPS has good high temperature and corrosion resistance. It is insoluble in any known solvent below 200 C. Compared with PPS, the latter is more conducive to use in higher temperature and harsher environment.
