Galloni Pressovac Touch with Dual Pyrometer


Item #: 265-0904

The system used by our Pressovac series casting machines was specially developed for jewelers where casting perfection is absolute: casting pieces have a very smooth surface, a very dense molecular structure and without defects like unproper filling, porosity and shrinkage.

Metal is inserted into the crucible and the flask positioned on the cradle inside the casting chamber. Casting cycle is fully automatic. The casting chamber is full evacuated by vacuum before melting, followed by argon gas supply to create an inert atmosphere.

Argon gas has an excellent gas fluidity which provides a cleaning effect of the molten metal and mold and guarantees a smooth filling of metal even of the most intricate patterns.

The casting temperature is attained and low frequency pulses are given to vibrate and mix the molten metal by keeping it homogeneous. Temperature is controlled by an optical pyrometer up to 2100°C (3812°F) for platinum and steel and by an immersion type "K" thermocouple inside the graphite crucible up to 1150°C (2102°F) for gold, silver and bronze.

At this stage, just by pushing a button, the whole crucible/flask system will automatically rotate 90° and the metal once poured in a homogeneous and controlled into the flask, it is automatically pressurized to 3 bars by argon gas. This high and quick pressurization is indispensable to obtain a proper and homogeneous filling, even at low metal/flask temperatures, for gold, silver, and bronze alloys, and above all, for platinum and special steels which have a very narrow melting interval, thus a very quick solidification.

This results in a very smooth surface due to the effect of the vacuum and a dense, well compacted casting due to the "over pressure" of 3 bars, which benefits both thick and thin sections.

The Dual Pyrometer Features:
  • Optical infrared pyrometer for temperatures up to 2100°C for steel and platinum.
  • Immersion "K" thermocouple for temperatures up to 1150°C for gold, silver, brass and bronze.
  • Option: immersion "K" thermocouple for temperatures up to 1450°C for gold alloys with palladium.
  • 1 year manufacturer warranty
