Instructions for Use:
1. Modeling : Maintain a minimum wax thickness of 0.3 to 0.4 mm. The wax pattern design should have lingual collars and no sharp corners. Lingual eyelet rings help support castings during firing.
2. Spruing (Single Crowns): Use direct sprues, 8-10 gauge, (3.3-2.6 mm diameter) and 1/2 in. (12 mm) long with adequate reservoirs. There should be no more than 1/4 in. (6 mm) of investment from the top of the pattern to the top of the investment.
3. Induction or Electrical Casting: When using induction casting machine, pre-heat the crucible. Set the arm speed to 400-450 rpm & set the power to high and be sure that the alloy is pulsating and slumping. The casting temperature of automatic casting equipment should be set for 2500 ?F (1370 ?C) with a five seconds heat soak.
4. Cooling: Allow casting ring to cool to room temperature. DO NOT quench in water.
