TCE - Centrifugal Casting

TCE are consistent, robust and easy to use vacuum centrifugal vacuum casting machines designed for small and medium casting laboratories. They can be manufactured in Class A or Class B. TCE in Class B are particularly suited for Platinum, Palladium and Steel while TCE in Class A has been especially designed to cast Titanium, Inconel, superalloys and other reactive metals. All models can also melt nonferrous and precious metals. The main difference between TCE in Class A and TCE in Class B is the degree of vacuum, leak-back rate and ppm of oxygen that are admitted during the process, that makes the TCE in Class A the best solution for casting Titanium-based alloys and intermetallic alloys. Also the choice of the vacuum pumps station and the induction power generator is different and it is chosen to get the maximum result in Titanium cast parts. Hence, TCE machines conceived in Class A are suitable for fields that require high quality control and low interstitial pick-up on the cast parts, like Aerospace, Medical and Automotive. TCE in Class B can instead be used where the price of the machines is an important factor and where no reactive metals are involved.

Key Features

Gas Wash Procedure Crucible and mould 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, Nitrogen or Helium gas (2)

Melting Advanced Self Tuning thermoregulation (ASTâ„¢) with exact temperature control of the molten 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
