Method for manufacturing magnetic powder core |
| abstract |
The present invention relates to a method for manufacturing a magnetic powder core. The method comprises a magnetic powder core raw material pre-treatment process, a mould filling process, a forming process and a mould releasing process, wherein the forming process involves applying pressure to a mould, holding pressure thereon and releasing pressure therefrom by means of a uniform-pressure medium. The present invention changes the traditional method of mechanical pressing, presses a mould in a uniform-pressure manner and enables the pressure to effectively be increased to more than ten thousand tons, so that the density and particle clearance of the magnetic powder core are more uniform to avoid the generation of breaking stress inside the magnetic powder core. |
