The ringless casting system Thermo-Fix 2000

The ringless casting system Thermo-Fix is the first system which allows free expansion of the muffle in all directions. The fit of crowns and bridges improves significantly compared to conventional systems wherein the expansion will naturally take the direction of least resistance, i.e. upwards. With the Thermofix system, the setting expansion is possible both laterally and vertically, which not only improves the fit but also reduces adjustment work and improves the economics of the process.

The system consists of base formers in the usual sizes 1, 3, 6 und 9, a special foil in the respective sizes which closes with velcro onto the base former and an adhesive rail. The base former and the inner side of the foil require an evenly applied coverage with silicon spray before pouring the investment. After positioning the wax model onto the base former, the investment (mixed as usual with liquid and water) is poured into the ring. After a few minutes, which are indicated by the color temperature indicator on the foil ring, the foil can be removed, allowing the muffle to expand freely in all directions while setting.

The setting expansion will be complete after approximately 25 minutes following the removal of the foil ring. The muffle can then be placed into the preheated oven. As Thermofix improves the quality of the fit of crowns and bridges, the system also improves process productivity especially regarding non-precious alloy restorations.


The phosphate-bonded investment Vesto-Fix® is graphite-free and especially suitable for non-precious alloys. Both regular and speed heating is possible. Technicians can control the fit by adjusting the ratio of liquid to distilled water in order to meet their specific requirements. The high-quality, controlled raw materials and the gentle mixing process make sure that users will experience consistent, replicable accuracy and quality. De-vesting cast objects from a Vesto-Fix® muffle is easy.

Diavest Turbo is the DFS Diamon investment for partial framework (speed heating). Diavest Turbo is phosphate-bonded und graphite-free.

Orovest has become an increasingly popular investment as it is not only suitable for precious alloys but also for press ceramics including lithium disilicate.

All DFS Diamon investments are packed with sufficient liquid in different packaging units between 4,8 kg and 20 kg. The expansion liquid is also available single in 1, 3 or 5 liter sizes.

Adhesive spray and Kera-Sep spray

Both sprays are important and helpful accessories for casting processes. The adhesive spray is designed for the application of wax relief parts before casting. It leaves a thin layer when evenly sprayed onto either hardened or unhardened models. Wax relief parts stick and will not detach during the investment vibration. Modellations are enhanced as waxing of single parts is not required.

Kera-Sep Spray is a silicone-free separation spray for ceramics against plaster. We recommend spraying the objects twice at a 1 min interval, spray traces remaining on the ceramics burn without residue.
