INSTRUCTIONS
FOR USE
|
| Modeling | Maintain a minimum wax thickness of 0.3 to 0.4 mm. |
| 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. |
| Spruing (Multi-Units & Bridges) | Use a 6 gauge (4.1 mm diameter) runner bar, connecting the units to the bar with 10 gauge (2.6 mm diameter) sprues 1/8 in. (3 mm)long and joining the bar to the sprue base with 8 gauge (3.3 mm diameter) and 1/2in. (12 mm) long sprues coming from a domed central entry point. 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. |
| Alloy Quantity | 10.5g/cm3 * (Wax Weight) = Required Alloy Quantity. |
| Investing | Use debubblizer and blow off any excess before investing. Required investmet: Phosphate Bonded Follow the manufacturer's instructions. |
| Burnout | After adequate set-up time, place the ring(s) in a room temperature oven and raise the temperature to 705 °C / 1300 °F, hold for 1 hour plus 10 minutes for each additional ring. If you are using a rapid fire investment, follow the manufacturer's instructions. |
| Reusing Cast Alloy | Use only clean buttons and at least 35 percent new alloy. |
| Crucible Type | Graphite / Ceramic |
| Torch Casting | Cast with oxygen and natural gas or oxygen and propane using a borax flux for optimum results. |
| Induction or Electrical Casting | Use a graphite lined crucible and a casting temperature of at least 212ºF/100°C over the liquidus temperature. Every casting machine is different. The casting temperature may require adjustment based upon the alloy and the amount of metal being cast. |
| Cooling | Allow the casting ring to cool to room temperature, do not quench. |
| Divesting and Cleaning | Divest and sandblast with 50 micron aluminum oxide, be careful of margins. |
| Pickling | Do not pickle. |
| Soldering | Check that the solder joints are sufficiently large (6-9 mm²). Soldering gap approximately 0.05-0.2 mm. The soldering surfaces should be parallel and pre-polished. Allow the soldered case to cool slowly after soldering. |
|
Recommended Solder |
Use: LO |
|
| Hardening | No hardening condition |
| Softening | Soft condition is As Cast |
| Polishing | Polish with any convential polishing brushes and felt wheels using Tripoli ,rouge and tin oxide. Soft, medium bristles, chamois, or rag wheels are acceptable. |
