Isitofu semagnethi ebunjiweyo yeferrite, iimagnethi ezibotshelelweyo zeferrite, zezo zimagnethi zeferrite ezisisigxina ezenziwe yinkqubo yokutofa. Ii powders zeferrite ezisisigxina ezidityaniswe nezibophelelo zeresin (PA6, PA12, okanye PPS), zilandelwa ngokutofwa ngokungunda, iimagnethi ezigqityiweyo zinemilo enzima kunye nokuchaneka okuphezulu komgangatho.
