Green density, measured before the part reaches the furnace.

A pressed part leaves the die as a semi-solid shape, powder held together by binder and roughly the dimensions of the finished component. Density variation at that point is a press adjustment. After sintering it is scrap. GGC brought X-ray green density measurement to these industries in 2015 with the Density Comparator.

WHAT MATTERS AT THE PRESS
Before sintering
The last stage where density is still correctable
Non-contact
X-ray transmission, nothing touches the green part
Master and sample
Every part judged against a known good one

Range and resolution depend on your material and geometry

ONE SYSTEM, NOT A RANGE

This is the only GGC product that applies here, and that is deliberate. The thickness, coating weight and vision systems on the rest of this site are built for continuous strip moving through a mill. A pressed part is a different problem, so it got a different instrument.

If you are measuring something we have not built for yet, the custom measurement group is the right first conversation. Custom measurement solutions →

WHY X-RAY

Nothing touches the green part

A green part is powder held together by binder. It is strong enough to be handled and not much more. Any measurement that presses, clamps or probes it risks marking the part, and on a part that fragile the act of measuring can change the thing being measured.

X-ray transmission reads straight through, without contact and without preparing a sample. That is the reason the comparator is built around it, and the reason a part measured on the way to the furnace is still a part when it gets there.

Measured without contact,
before the furnace.
The comparator measures the part you are about to sinter, not a sample cut from it.
