More process reliability
The desire to detect and counteract undesirable developments at an early stage of a production process means enabling the density of green parts to be determined. However, these are usually water-absorbent or have water-soluble binders, which is difficult or impossible to reproduce with repeat accuracy for the Archimedean measuring principle with conventional variants. An absorption of liquid always means a deviation from the real density value. In practice, a coating of wax is used to weigh a component in a defined time. This process requires appropriate qualification and experience on the part of the tester. Here, too, the factors of lack of skilled workers and human influence play a decisive role.
