Compression molding is cost effective when higher volumes are required compression molded magnets are best produced in tens or hundreds of thousands of magnets per production run. Advantages. A higher ratio of magnetic material powder to binder gives higher magnetic performance than the injection molded magnets (higher magnetic loading)
As for molded magnets by injection molding also compression molded magnets requires a tool to each design. The most common material is Rare Earth material NdFeB and epoxy is used as a binder. Compression bonded magnets are isotropic and have the advantage to more advanced shapes compared to sintered magnets.
