Tungsten Carbide Manufacturing

Yesterday, I got the opportunity of visiting the tungsten carbide factory to view the whole tungsten carbide manufacturing process, including how tungsten carbide mixture are made, what exactly the various drawing dies look like and how those tungsten carbide rod were extruded. For me, the above all sounds abstract to me before yesterday, but now, not any more. This visit can be definitely called my first practical lesson introducing me to real tungsten carbide world.
