The compression molding method is the most mature preparation method for making tungsten alloy balls, and the process is also relatively simple, which means the volumetric method is used to automatically press and form the powder. The defects are also relatively obvious. Due to the limitation of the mold, there is an annular belt in the middle of the ball blank and the pressing crack is prone to appear at the annular belt. This is related to the resistance of the powder movement to the mold wall. The advantage is that it is easy to realize automatic compression, but the granulation process of the mixture needs to be increased, the mold is worn out, and the efficiency of producing micro-balls is low.
