The cold compression of the diamond powder blend, enables to realize semi-finished pieces which can be manipulated and are of similar shape to the finished product.
This phase of the process of production improves the repeatability of the characteristics of the finished product and increases the sintering productivity.
The cold presses differ substantially in gravimetric and volumetric, depending on the used method for the subdividing in doses, of the metal and diamond powder blends with which they are fed.
The volumetric cold presses allow to obtain higher productivity, but they imply the preliminary granulation of the powder blends.
In the most complete models, the use of a robot enables the automatic check of the weight of the pre-pressed pieces and their stock.
