Txhaj tshuaj molded ferrite hlau nplaum, sib txuas ferrite hlau nplaum, yog cov hlau nplaum ruaj khov ferrite tsim los ntawm cov txheej txheem txhaj tshuaj. Permanent ferrite hmoov compounded nrog resin binders (PA6, PA12, los yog PPS), ua raws li los ntawm kev txhaj tshuaj los ntawm pwm, cov hlau nplaum tiav muaj cov duab nyuaj thiab qhov raug siab.
