The Galloni “G” range casting machine are the latest and most technically advanced induction heated vacuum “over pressure” machines currently available worldwide, featuring low frequency generators and fully proportional computer-controlled power output.
The operator has simply to charge the crucible, place the casting flask in position and press one button!
The G1 machine is equipped with a 3” (75 mm) touch-screen 2 colour LED control system and the G3 with a 5.7” (128 mm) TFT colour touch-screen.
Both machines lead the operator logically step-by-step through the casting sequence, irrespective of the type and quantity of the alloy. Frequency and power output are automatically and continuously adjusted and, just ahead of attaining the pre-set casting temperature, the computerized control starts modulation of heating current by delivering low frequency impulses, thus inductively stirring the melt. Then, when all parameters are achieved and the temperature “spread” is no more than 4 °C either side of the set point, pouring starts automatically followed by strong pressurisation of molten metal by inert gas. The complete cycle can be performed in minutes
