Injection Molded Neodymium Iron Boron (NdFeB) magnets are manufactured by an injection process of pre-mixed magnetic powder with thermoplastic binders e.g. Nylon 6 or 12 or Polyphenylene Sulfide (PPS) which produces an accurate and homogeneous magnetic part. Through this process various shapes of magnets can be directly molded into or over the components e.g. shafts, cams, inserts and the like eliminating some steps in assembly. With the injection mold process very complex shaped magnets can be achieved with extremely tight tolerances and a broad range of magnetic properties and characteristics. Injection Molded magnets have good corrosion resistance in water and industrial solvents.
