Plastic injection magnet wholesale
Injection molded magnets are produced by injecting the special pellets into the mold. This kind of magnet covers a wide range of characteristics as bonded magnets, including heat resistance and higher magnetic properties. Injection molding technique offers flexible shape design as well as over-molding and insert-molding with other parts for easy assemblies.
The advantage of injection molded magnets.
For this kind of isotropic magnets, any magnetization direction can be applied. This is a congenital advantage to manufacture the multi-polar magnets.
Injection molded magnets have excellent dimensional accuracy and serial productivity.
Thin wall thickness and complex shape can be manufactured.
Over-molding and insert-molding with other parts, like back yoke, hub, shaft is readily available, as well as injection other polymer parts can be incorporated.
The polyer binders’s volume fraction of injection molded magnets higher than the compression molded magnets. It will provide adequate protection against corrosion without coating in most applications.
