Know the green density of a pressed part before it goes into the furnace. GGC introduced the Density Comparator to the ceramics and powdered metals industries in 2015.
Powder and binder are pressed in a die into a semi-solid shape, roughly the dimensions of the finished part.
A part of known good density is measured and held as the reference. The panel has a dedicated MEASURE MASTER control for it.
Production parts are measured against that master. X-ray transmission through the part is the measurement.
The result is a percent deviation from the master, on the panel meter, before anything reaches the furnace.
The panel is deliberately plain. Power, gauge healthy, gauge ready, then two buttons: measure the master, measure the sample. The result is a percent reading an operator can act on without interpreting anything.
When a batch drifts outside the allowable range, the press operator adjusts the press. The alternative is finding out after sintering, when the batch is already scrap.
The whole unit stands on castors. It is built to be wheeled to the press that needs it rather than installed once and worked around, which matters on a floor running several presses and several part numbers.
Sintering is the point of no return. Everything before it can be corrected; nothing after it can. Density variation that is invisible in a pressed part becomes dimensional and structural variation in a fired one, and by then the batch is finished.
Measuring green density before the furnace turns a scrapped batch into a press adjustment. Range and resolution depend on the material, the part geometry and the press, so GGC quotes them against your part rather than publishing a figure that would be wrong for most of the parts that read it.
Tell us the material, the pressed geometry and the tolerance you hold after sintering. We will tell you what the comparator resolves on your part.
