Injection Bonded Magnet Manufacturing Process has a unique advantage of in-situ molding of steel shafts, brass bushes etc while molding of the magnets. Monobloc Molding with metal and other objects make a wide range of applications possible. Monobloc Molding also reduces the number of operations required to manufacture the magnet assembly. Moreover, it leads to reduction in costs and at the same time enhances the bond between the metal insert and the  magnet. Insert Molding / Over Molding is preferred wherever possible so as to improve the mechanical strength of the assembly of magnets.

Following are some of the alluring features of insert molded magnets and over molded magnets:

• Tight control and consistency in the magnetic properties.
• Extremely tight off tool tolerances (0.01 mm) is achievable.
• High mechanical strength and less fragile than sintered magnets.
• High tensile strength for applications requiring high rotational speeds
