The invention provides an iron-based magnetic powder forming process and equipment, the process is realized by the iron-based magnetic powder forming equipment, and the process comprises the following steps: taking a proper amount of iron-based magnetic powder, and placing the iron-based magnetic powder on a mold for heating; the heated iron-based magnetic powder is pressurized through a pressing machine, so that the iron-based magnetic powder is extruded by the mold; and when the iron-based magnetic powder is pressurized to preset pressure, the pressurized iron-based magnetic powder is subjected to pressure maintaining for a period of time and then taken out, and the formed iron-based magnetic powder is obtained. According to the iron-based magnetic powder forming process and equipment, by arranging the iron-based magnetic powder forming equipment, the situation that internal stress is generated in the formed iron-based magnetic powder material, and the magnetic performance of the formed iron-based magnetic
