TCE

TCE in Class A are robust and easy to use vacuum centrifugal casting machine especially designed to cast Titanium and other reactive metals.

Main differences with respect to TCE in Class B are 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 Ti cast parts, like Aerospace, Medical and Automotive.

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 and other reactive metals. All models can also melt nonferrous and precious metals.

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.

Regarding the mold size and crucible capacity, today with TCE you can cast up to 2 kg Ti and use flasks up to 140mm in diameter and 380mm in length.

We are also developing larger machines under customized specifications for what concerns Ti crucible capacity and Flask mould size. In case you are interested in getting a quotation for non-standard casting machine do not hesitate to send us your technical specifications.

Crucibles for Titanium have been designed to avoid alloy contamination and to withstand the high chemical and thermal shocks involved in Titanium melting.

TOPCAST also supplies special investment powder for Titanium casting particularly suitable to avoid alpha-case structure in the cast parts.

  • Level of vacuum reached is extremely high
  • Leak-back rate is carefully minimized
  • Oxygen ppm in final atmosphere can be precisely measured and controlled
  • Induction frequency and magnetic field intensity are specifically designed for reactive metals melting
  • Cast Part traceability: These machines are provided with a Monitoring System based on a PC data logger which is taking process variable samples in both numeric and graphic form, making them available for the off-line Reporting program able to perform specific analysis and data comparison activities.

TCE in Class B are vacuum centrifugal casting machine:

  • robust and easy to use
  • ?designed for small and medium casting laboratories.
  • suited for steel, nonferrous and precious metals, including platinum, palladium.
  • best where the price of the machines is an important factor and where no reactive metals are involved.

Regarding the mold size and crucible capacity, you can cast up to 4 kg steel and use flasks up to 140mm in diameter and 380mm in length. We may also develop larger machines under customized specifications for what concerns crucible capacity and flask mould size. In case you are interested in getting a quotation for non-standard casting machine do not hesitate to send us your technical specifications.

 

Technology & 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 (AST™) 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.
