Production process of cemented carbide button
1. The manufacturig process begins with the composition of a specific tungsten carbide powder mixture- tailored for the application.
2. This powder is compacted into a form.
3. In a high- temperature sintering furnace, the tungsten carbide structure of the blank is shaped at precise temperatures for strictly defined periods.
4. During this heat treatment, the tungsten carbide blank undergoes shrinkage of some 50% in volume.
5. The sintered tungsten carbide component gains its final finish by additional grinding, lapping and/ or polishing processes.
