A method is provided for forming thermoplastic material (30) using rotary forging. A volume of a thermoplastic material is delivered. The thermoplastic material is transported between a first rotating forging device (40) and a second rotating forging device (50). The first forging device defines a first forging region in its surface (42), which receives the thermoplastic material. The thermoplastic material is at or above a forging temperature and flows into the first void region and shapes a core element from the thermoplastic material. The thermoplastic material is substantially solidified into the core element (70). Then, the core element is transferred from the first rotating forging device.
