Injection molding ferrite small magnetic ring manufacturing process;
Injection molded ferrite small magnetic rings are manufactured through injection molding technology. Firstly, mix the ferrite powder with a suitable polymer resin and add an appropriate amount of additives and pigments. Then, the mixture is injected into the mold and subjected to heating and pressure treatment to solidify and form. Finally, injection molded ferrite small magnetic rings with certain magnetic properties were obtained through processes such as drying and sintering.
