By doing insert molding, magnetic material can be directly molded into or onto other assembly components without further assembly process
It is a new technology to achieve adjustable magnetic properties, composite molding, elastic magnetization and high mechanical strength
Injection molded magnets can be of very complex shapes with high precision, typically, tolerance is +/- 0.005mm, it is suitable for high precision parts
The material is harder to be cracked or chipped than sintered magnet.
