Production process of tungsten carbide insert button
1. The manufacturing 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.
