Key Features
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) Compared with the traditional crucible protection with flow-meter regulation the consumption of gas is dramatically reduced and the alloys oxidation is minimized Moreover the crucible life is increased: TVC series crucible last up to 250 – 400 casting cycles according to the graphite quality
Melting Advanced Self Tuning thermoregulation (AST™) with exact temperature control of the melted alloys Two Set-Points available: Homogenization and Casting Temperature Medium frequency induction heating stirs the melted alloy and leads to a perfect homogeneity Pulse Stirring Management (PSM™) for an extremely low frequency stirring Highest power density in the market features strongest stirring and low gold losses
Injection and Compression When the stopper lifts up. it is very important to control the injection rate to avoid turbulences TVC has the unique feature to have the injection rate controllable and programmable (IRC™) The metal enters smoothly inside the mould (4). Then, after filling and during the solidification phase, a strong com pression takes place on the tree (5) No turbulences in filling and high compression rate lead to a large reduction of shrinkage porosity phenomena
Tree protection after casting Thanks to the double chamber concept, after the solidification phase, the flask cools down in a protective atmosphere while at the same time you can load your alloy in the melting chamber for the next melting. This operation will allows an overlapping of the casting cycles which will give you the ability to protect longer the tree before removing it without losing time and productivity
