Metal Injection Molding Wear-resistant Snow Tire Anti-skid Spikes

Powder injection molding is one of the methods for preparing tungsten alloy balls. Powder injection molding technology is the product of the combination of plastic injection molding technology and traditional powder metallurgy technology. It is known as the most popular powder metallurgy near-final shape forming technology in the world today.

The advantages of this method for preparing tungsten alloy balls 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 balls prepared by this method have high dimensional accuracy and small roundness, and can be processed less or not, reducing the subsequent heat treatment process. There are advantages and disadvantages. The disadvantage of this method is that there may be internal defects in the forming process or deformation and cracking during the sintering process, which cannot achieve the ideal performance of tungsten alloy balls.

In fact, the production process and preparation process of each product are basically the same, but the key is to make the product quality meticulous and detailed in the sintering, injection and related processes of the product, so as to make a good product.
