Everything You Need to Know About Tungsten carbide rods


Tungsten carbide is a famous tool material because it has lots of performance, such as high hardness, high strength, wear resistance, corrosion resistance, impact resistance, and chemically stable. As tungsten carbide can be made into so many different tungsten carbide products, tungsten carbide rods are one of them. And in this article, you can get information about tungsten carbide rods from the following aspects:

1. The application of tungsten carbide rods

2. How to manufacture tungsten carbide rods

The application of tungsten carbide rods

Tungsten carbide rods are widely used for high-quality carbide tools, such as milling cutters, end mills, drills, and reamers. It can also be used for cutting, stamping, and measuring tools. It is used in the paper, packaging, printing, and non-ferrous metal processing industries.

How to manufacture tungsten carbide rods

There is not only one method to manufacture tungsten carbide rods. Tungsten carbide rods can be made by extrusion, automatic pressing, and cold isostatic press. 

Extrusion pressing is the most popular method of producing tungsten carbide rods. It is a very practical way to manufacture long solid carbide rods. In extrusion pressing, paraffin and cellulose are widely used forming agents. However, its time-consuming drying process is the weakness that we have to pay attention to.

Automatic pressing is pressing the tungsten carbide rods with a die mold. This method is the most common and is suitable for short tungsten carbide rods. During the automatic pressing, workers add some paraffin as a forming agent, which can increase efficiency, shorten production time, and save more costs. And paraffin is easy to let out during the sintering. However, tungsten carbide rods after automatic pressing need to be ground.

Cold isostatic press(CIP) is the latest technology for making carbide rods. During the dry-bag isostatic pressing, the forming pressure is high, and the pressing process is fast. Tungsten carbide bars after dry-bag isostatic pressing have to be ground before sintering.
