[How Carbide Powder is Pressed]
Tungsten carbide shapes are made from a powder which is typically tungsten, carbon, cobalt and wax to bind it all together.
This is a carbide press. At top is a ram. The powder is poured into the press cavity (the die) then the ram comes down and compresses the powder. Once the powder is fully pressed the top ram withdraws. There is a second ram at the bottom of the cavity that comes up and pushes the part out of the cavity.
The pressed parts are then presintered. In this step the wax is melted out. This leaves a piece of "green carbide" or "green state carbide". Since the wax has been melted out it is just powder pressed together. It is actually weaker than side walk chalk. It can be machined easily in this state although great care is required.
It is at this step that carbide parts get chipped edges. Some parts, such as saw tips, are made in large and very large batches. They are moved by conveyors and often poured into trays for final sintering. If this not done carefully one square edge impinging on another can cause chipped edges in the carbide parts. By contrast you can use a .410 shotgun to fire fully sintered saw tips at a concrete block wall without damaging the saw tips.
The final step is sintering in which the carbon is forced into a relaxed tungsten matrix creating tungsten carbide grains and those grains are enveloped in a binder or matrix of cobalt of similar.
During the final sintering the parts shrink dramatically. Exactly how much shrinkage will occur is difficult to predict exactly. Parts are usually designed to be produced a bit oversize.
