NFCast - Densometer

Product Description

The DIU comprises two parts – A Vacuum Sampling Machine (VSM) and a Density Analyzer (DA). The Vacuum Sampling Machine has a Vacuum Chamber in which a test crucible containing molten metal sample is kept. It is then subjected to a controlled vacuum of 80 mbar till solidification is complete. Another metal sample is solidified in Air.

These samples are carried to the PLC-based Density Analyzer. By following the specified procedure, densities of the two samples are determined. The Density Analyzer compares these and automatically generates a Density Index which is the quantitative measure of the porosity in the melt.

Major features / advantages in our machine is as follows.

I) Vacuum Sampling unit:

In Vacuum Sampling Machine, we solidify Aluminium molten metal sample at 80 mbar constant pressure for 4 Minutes. This constant vacuum pressure of 80 mbar is very important for consistency in readings. On display unit we can see the actual values and set values of vacuum pressure.
We can set time as per solidification requirement. We set it at 4.00 minutes. On display unit we can see the actual value and set value of timer.
There is small buzzer and indicator which gives signal after completion of set time and get off after 5 seconds, so that operator knows that cycle is completed. Mean time he can do other work and not necessary to stand in front of machine for 4 minutes.
Vacuum Sampling machine is portable - Trolley type and sturdy. We can keep the same near furnace where you take the metal sample.

II) Density Analyser:

Our unit is fully developed, proven and standard unit. Testing method is as per standard procedure.
Density Analyser gives direct reading of Density Index in %, which displays on front Display unit. There is Display unit and small inbuilt Printer. This report includes your heat no, operator name, date, time, Density of Air cooled and Density of Vacuum Cooled sample and Density Index in %. Please find below sample print out for your ready reference. This printing facility is not available with other make machines.
Simple and easy to operate.
No manual calculations. All calculations will be done by PLC.
There is USB port to this unit. You can store the readings in our machine and further can be loaded on computer with the help of Pen-drive for further analysis.
