    40 and more crowns and/or bridge elements may be produced with a mould in the small ring and three or more partials may be casted with a mould in the large ring in one cast. Cast...

  • Page 7: Safety Instructions

    Ti-Research Safety Instructions For safe operation the following instructions are mandatory: Intended Use Cast Ti-Research The usage of is intended for the production of castings with the centrifugal casting principle by qualified users only. Any other application is not intended use and not permitted.

  • Page 8: Installation And First Operation

    Ti-Research For the usage of torches the local safety regulations and precautions are to be obeyed. In case of defects or damages resulting in dangerous conditions for use the device is to be disconnected from the power supply and to protect against accidental use.
  • Page 9 Ti-Research Lift the top lid 2 by turning the lever 13 upward and turn it to the side. The mould holder inside the device must not be able to rotate free by hand operation. In case the mould holder rotates free proceed as indicated in the troubleshooting section.

  • Page 10: First Operation

    Ti-Research First Operation Before connecting to the power outlet check the specifications of your power supply with the specification of the device on the type plate. In case the specifications of the device do not match to your local power supply, the device must not be connected.

  • Page 11: Conversion Of The Device For Large Moulds

    Ti-Research Conversion of the Device for large Moulds Unscrew the three mounting screws of the mould holder with the small key (part of delivery). Take the mould holder and the 3 cm high adapter-ring underneath out of the device. Place the mould holder without the adapter-ring in the device and fix it by hand with the three short screws at equal torque.

  • Page 12: Production Of Castings

    Ti-Research Production of castings Depending on type and volume of objects to be casted three different types of mould rings may be used: small 30 mm high mould ring for crowns, bridges and small partial dentures, small 30 mm high mould ring with reduced volume for a few or even single...

  • Page 13: Invest

    Ti-Research Depending on the density of the alloys used different distances from the metal ring are recommended: non precious alloys approx. 1 cm to the inner side of metal ring precious alloys (reduced) approx. 1,5 cm to the inner side of metal ring precious alloys approx.

  • Page 14: Preheating

    Ti-Research Warning! The shaped edge of the metal rings must be free of investment. Preheating The mould and the crucible are to be preheated as usual according to the instructions of the invest material used. Casting After preheating the mould is to be taken out of the furnace and placed into the mould holder by turning the ring clockwise to the stop.
  • Page 15 Ti-Research Prior to the melting process or at least 5 seconds before pourring the device is to be switched on to reach nominal speed for casting. After reaching the liquidus point of the metal it may be pourred into the mould by turning the crucible holder handle 13 in a smooth move to tip over the crucible 11.

  • Page 16: Devesting

    Ti-Research Devesting After sufficient time of cooling down the casting may be taken out of the mould as usual for further processing.

  • Page 17: Maintenance And Servicing

    Ti-Research Maintenance and Servicing Maintenance The casting device requires no special maintenance. With respect to safe operation a visual check of the cabinet or other parts of the device and the power cord should be done before each use. The top lid 2 must close tight with the cabinet 1.

  • Page 20: Annex I: Correct Sprueing

    Correct Sprueing As common to any casting system some device dependent and physical properties have to be obeyed to obtain satisfactory results. The Waxdisk Cast The waxdisk of the – system replaces the sprue base known from other casting systems.

  • Page 21: Positioning Of Models In The Mould

    Ti-Research correct wrong It is important to avoid sprueing to a center sprue base but to mount each sprue radially to the waxdisk. To avoid turbulences and insufficient flow the sprues should be fixed side by side without any overlap (see illustration above).

  • Page 23: Annex Ii: Hints For Proper Melting

    – system suitable for almost all alloys used for dental appliances. To achieve a perfect cast the alloy must be melted completely, i. e. brought above the liquidus point completely into the liquid state. Most alloys in the liquid state contract to a spheric shape like a drop of mercury and may be moved easily under the pressure of the flame.
