The Smartest and Ultimate Casting Technology
The Galloni G1, G3 & G5 Series is the most advanced Induction Pressure/Vacuum Casting Machine currently available worldwide with fully proportional computer-controlled power output. The machine is fully automatic and controllled by a custom-built computer featuring a 5.7” TFT color touch screen leading the operator step by step through the casting process.The operator simply has to charge the crucible, place the casting flask in position and press one button ! Irrespective of the type and quantity of alloy, the frequency and power outputs are automatically adjusted and, just ahead of attaining the preset casting temperature, the computerized control system starts to modulate the heating current. Set point is thus achieved without overshoot and stirring of the melt is uninterrupted throughout. When all desired parameters are achieved, the computer delivers frequency impulses to the metal for five seconds to inductively mix and immediately after the automatic pour if the temperature “spread” is not more than ±1°C of the preset casting temperature. Automatic pressurisation of the molten metal by Argon or Nitrogen then follows.The G1 ,G3 and G5 Series is capable of performing a complete casting cycle within 3 minutes or a casting cycle and then a delay of 3 minutes may be set at the discretion of the operator to allow cooling of the crucible within the inert atmosphere. This can radically enhance crucible life. Conventional casting machines with unsophisticated “ON - OFF” heating control do not stir the melt when the heating power is “OFF” and some temperature overshoot is produced, with consequent degradation of the alloy. The G1,G3 & G5 Series embodies a solid-states medium frequency generator (for maximum stirring effect) and has a maximum melt capacity of 3 kg of fine gold. G1, G3 SERIES & NEW G5
