Powder injection molding is one of the methods for preparing tungsten ball. Powder injection molding technology is a combination of plastic injection molding technology and traditional powder metallurgy technology. It is known as the most popular powder metallurgy close-to-final shape forming technology in the world today.
The advantages of this method for preparing tungsten ball are: it can directly form small metal parts with complex shapes and high dimensional accuracy in large quantities at one time, and the density of each part of the product is uniform and the performance is excellent. The tungsten alloy ball prepared by this method has high dimensional accuracy and small roundness, and can be processed with little or no processing, and the subsequent heat treatment process is reduced.
There are advantages and disadvantages. The disadvantage of this method is that there may be internal defects during the forming process or deformation and cracking during the sintering process, so that the ideal performance of the tungsten alloy ball cannot be achieved.
