Die-Shot Monitor: Hydraulic Pressure
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.
| Parameter | Effect on the process | |
|---|---|---|
| Cavity Fill Pressure | Flow pattern and surface quality | |
| Impact Pressure | Flashing of the die | |
| Discharge Coefficient | Gate blockage, machine condition | |
| Intensification Delay Time | Shrinkage porosity | |
| Final Pressure | Shrinkage porosity |
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.
