Product Description
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 inert gas (either argon, nitrogen and helium) supply to create an inert atmosphere.
Inert gas has an excellent gas fluidity. This provides a cleaning effect of the molten metal and mold which 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, keeping it homogeneous and under an inert atmosphere. Temperature is controlled by an optical infrared pyrometer up to 2100°C (3812°F) for platinum, palladium and steel and by an immersion type "K" thermocouple inside the graphite crucible up to 1150°C (2102°F) for gold, silver, brass and bronze.
At this stage, just by pushing a button, the whole crucible/flask system will automatically rotate 90° and the metal is poured in a homogeneous and controlled flow into the flask. It is automatically pressurized to 3 bars by inert 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 (3812°F) for steel and platinum.
- Immersion "K" thermocouple for temperatures up to 1150°C (2102°F) for gold, silver, brass and bronze.
- Now supplied with larger touch screen for ease of use.
- Option: Immersion "S" thermocouple for temperatures up to 1450°C for gold alloys with palladium.
- 1 year manufacturer warranty
