The hydraulic fluid
transfers the energy stored in the accumulator, to the molten metal, as a
combination of pressure and speed.
The Hydraulic Pressure acts on top of
the shot ram. However, the fluid below the shot ram creates a 'back-pressure'
as it is exhausted to the tank. Die-Shot measures the pressure on both the
Inlet and the Exhaust ports and thereby calculates the actual pressure on the
metal.
By combining the measurements of
Hydraulic Pressure, Plunger Position and Plunger Speed, Die-Shot provides you
with a view into the heart of the Die Casting process.

It is not necessary to be able to
interpret complex charts, because Die-Shot calculates each of these parameters
automatically and displays them along with their target
values.
To understand and monitor the condition
of your machine and its interaction with the die, you need to measure the
hydraulic pressures.
