Gas Wash Procedure

• Crucible loading operation introduces oxygen
• The Gas Wash Purge procedure removes the oxygen(1) in a very fast and efficient way and then refills back the chambers with Argon or Helium gas(2)

Melting

• Advanced Self Tuning thermoregulation (ASTTM) with exact temperature control of the melted alloys.
• Accurate control of the temperature with a proprietary narrow band optical pyrometer or with rotating thermocouple
• Medium frequency induction heating stirs the melted alloy and leads to a perfect homogeneity.
• Magnetic field frequency has been studied for best coupling and energy transfer

Injection and Compression

• When the charge is molten, the coil is retracted and the arm starts to spin.
• During the spinning the metal gets out from the crucible and enters the flask.
• Rotational speed profile, which controls the injection rate, can be regulated digitally for a consistent and reliable mould filling.
• The final speed will compress the tree during the solidification phase to reduce shrinkage porosity.

Tree protection after casting

• After the solidification phase, the flask cools down in a protective atmosphere to avoid oxidation.
• A blinking lamp will signal the operator that the cycle has ended and the flask can be removed
