INJECTION AND HOLDING PROFILE
Injection Profile
The injection profile can be programmed in 6 steps with 5 stroke trigger points.
The injection start position is taken as the current stroke position at that time.
Example
Step 1: Injection from screw stops position to 70.0 mm with speed 30mm/s
Step 2: With 20mm/s speed upto 55.0 mm
.... and so on as per the profile programmed.
With time dependent switch over to hold on pressure, the actual switch over stroke will be indicated.
With stroke dependent switch over to hold on pressure, it will occur at 5.0 mm.
If steps are switched out, then the next trigger point is merged in its place for injection speed. Therefore the speed value of the last point remains unchanged until switch over to hold on phase. .... and so on as per the profile programmed.

With stroke dependent switch over to hold on pressure, it will occur at 5.0 mm.
If steps are switched out, then the next trigger point is merged in its place for injection speed. Therefore the speed value of the last point remains unchanged until switch over to hold on phase.
Similarly the hold on profile can be programmed in 6 stages and with 5 time dependent change points.
The switch over time is taken as the start time, for Holding pressure - 1 stage.
Example
Stage 1: After switch over to holding pressure, the holding pressure of 40 bar for 3.0 sec. is applied.
Stage 2: Holding pressure of 30 bar for 2.0 sec.
.... and so on as programmed.
