Tungsten Carbide Rods
The Tungsten Carbide Rods(also named as Cemented Carbide Rods), are used in making high quality carbide cutting tools for the machining of heat-resistant alloys and Ti alloy, such as end mill, drill, reamer.

How does Tungsten Carbide Rods Manufacture
We use Fine and Ultra Fine grain size of tungsten carbide powder. To control uniform grain size, wet milling is the first step.
Before extrusion, it shoud be dried and granulated. Extrusion is the main way to press long carbide rods like 300, 310,330mm. We manage diffrent diameter carbide rods with different extrusion machine to improve production efficiency. We can manage diameter from 2-30mm.
Sintered under 6Mpa pressuer and 1400℃+ .
Every batch after sintered, we will analysis firstly. Coercive force, Hardness, TRS, Density, Metallographic. To ensure the carbide rods we send to customer is qualified.
Cutting to short
The sintered tungsten carbide rods is 300-330mm standard length, The auto cutting machine was needed to cut it to standard or nonstandard short carbide rods as required like 45mm, 50mm, 150mm long etc.
The next step is Precision Grinding, we plan to add grind machine to service customer.
