Spruing: Following the rules for dental applications (see General Instructions for Use)
Investment: Phosphate-bonded investment materials (Cehacast P or Cehacast Speed)
Preheating: 850 °C, 30 to 120 mins until end temperature, depending on size of mould
Casting: 1380 °C, possibly increase by 20°C–30°C for resistance-heated vacuum pressure casting. Graphite crucible or open flame with ceramic crucible
Finishing: With carbide burs and/or ceramic-bonded stones. Always grind in one direction only! Sandblasting at a flat angle, using 50–125 µm aluminium oxide. Pressure should not exceed 2 bar
Cleaning: Steam jet cleaning or boiling in distilled water
Oxide firing: 5 mins at 950°C without vacuum. Afterwards, always clean in a preheated acid bath, e.g. Neacid, (for 10 mins) or sandblast with 50–125 µm aluminium oxide. Pressure should not exceed 2 bar. Clean thoroughly with a steam jet
Soldering before firing: Orplid Ceramic solder 1020 / Orplid Ceramic solder 1070 (white)
Soldering after firing: Orplid solder 760
Firing: For normally expanding ceramic materials (e.g. CeHa WHITE® Classic)
Firing temperature of the ceramic material: CeHa WHITE® CLASSIC: 20°C higher for opaquer firing
