There are four common methods for preparing tungsten ball in the current market, namely: compression molding method, extrusion-cutting rotation method, disc pelletizing method, and injection molding method. In the previous issues, we learned about the preparation methods of the compression molding method and the disc pelletizing method, and today we will learn about the extrusion-cutting rotation method.
The extrusion-cutting rotation method of the tungsten alloy ball is to pre-press the material doped with plasticizer in the extruder, and then cut the extruded round bar into small cylinders, and then use the cone pelletizing machine. Roll into a ball, or install a small cylinder in a disc ball machine to roll into a ball. The tungsten alloy ball preparation method is easy to control the ball diameter, and the production efficiency is higher than other methods.
