Control the sand where it’s poured.
Not just where it’s mixed.
V-CAT tests compactability, moisture, permeability and strength in-line at the moulding machine. It feeds every reading back to the mixer, and rejects the moulds that fall outside spec - in 12 to 22 seconds.
Sand doesn’t arrive the way it left the mixer.
Control compactability perfectly at the mixer and it still drifts on the way to the mould. A line stoppage adds dwell time; the distance from mixer to moulding matters; mixing raises the sand temperature; and ambient temperature and humidity move through the day and the seasons.
By the time the sand is rammed, the number controlled upstream is not the number in the mould. The only place to catch that is at the moulding machine itself.
Dwell time · distance · temperature · humidity all move the number between mixer and mould.
A second control loop, right where it counts.
V-CAT closes the gap between mixer and mould: it tests the sand going into the machine, corrects the mixer, and stops bad moulds from being poured.
Test at the mould
An arm extracts sand from the stream and runs compactability, moisture, permeability and strength - as often as every mould.
Reading ↓Feed back to the mixer
Set-point correction goes to the mixer compactability controller and V-DOSE water dosing, so the next batch is already adjusted.
Set-point ↓Reject out-of-spec moulds
A marking output fires on your LCL / UCL limits. Moulds that fall outside spec are flagged and rejected automatically.
Accept / rejectFour numbers that decide the casting.
Cycle: 12-15 s without permeability · 15-22 s with permeability.
Compactability
Squeezing type - the master variable for mould quality.
Set-point loopMoisture
Estimated from electrical properties, correlated to moisture.
EstimatedPermeability
Mould permeability - gas escape and blow-defect risk.
+3–7 sStrength
Mould strength (penetration), or green compression strength (optional).
PenetrationV-CAT instruments the whole green-sand plant.
VCAT-II at the moulding machine is one node. The V-CAT family tests and controls the line end to end, from the mixer to the cooler, on one networked, SCADA-ready backbone.
