| Investment: | Phosphate-bonded investment materials |
| Preheating: | 800 °C, 30 to 90 mins until end temperature, depending on size of mould |
| Casting: | 1300°C – possibly increase by 10°C–20°C for resistance-heated casting units. Use ceramic crucible (graphite crucibles also possible) |
| Finishing: | With carbide burs and/or ceramic-bonded stones. Always grind in one direction only! Sandblasting at a flat angle, using 110–150 µm aluminium oxide. Pressure should not exceed 2 bar |
| Cleaning: | Steam jet cleaning or boiling in distilled water |
| Oxide firing: | 10 mins at 800°C without vacuum. It is imperative to remove the oxides. Preferably, acidify for 10 - 15 minutes in a warm and clean neacid bath or carefully blast with 110 μm aluminium oxide. Finally, steam off thoroughly. |
