  • Multi-part axial powder compression mold for complex parts
    Patent number: 9259784
    Abstract: A method for manufacturing a titanium acetabular cup shell includes obtaining a titanium powder. A three part mold having a first part with a part-spherical inner surface, a second ram part with a part-spherical outer impact surface and a third ram part with an annular impact surface are provided to compact the titanium powder. The second and third parts are aligned along an axis within the first part. The second part is aligned along a center axis within the annular impact surface of the third part. The first mold part is filled with the titanium powder. The second mold part-spherical outer surface and the third part annular surface are moved towards the part-spherical inner surface of the first part into contact with the powder. The powder is compacted with the second part part-spherical outer impact surface and the third part annular impact surface to about 50% of its initial volume.
