    PROCESSING TECHNIQUE

    Use investments for high-heat Chromium-Cobalt partial denture alloys only. Burnout at the temperatures and time recommended by the investment manufacturer or at a minimum of 1,850°F (1,010°C) for 1.5 hrs.

    TORCH CASTING

    1. Use a single-orfice tip or a multi-orfice tip.
    2. Set gauge at 20 psi oxygen and 8 psi acetylene.
    3. Give the spring-type casting arm three turns on an average casting.
    4. Place a sufficient amount of alloy in the preheated crucible.
    5. Heat the alloy evenly until the alloy begins to melt. At this point, drop a small amount of flux onto the heated metal to make the piece flow together. When the metal melts into a single mass, release the casting machine arm.
    6. Allow the casting arm to rotate for a minimum of twenty seconds. Then remove the mold and set it aside to bench cool.

    INDUCTION CASTING

    It is crucial to follow the manufacturer's instructions in the operation of your specific equipment, due to the various types of induction machines available on the market (such as Manual, Semi-Automatic, and Fully Automatic, etc.). Exercise care in placing virgin metals or buttons in the crucible. Do not drop in ingots. Instead, use large tweezers to load the crucible, which will help prevent cracking of the crucible. For manual operators, when all the metal has melted together as one joined mass, release machine immediately to prevent overheating of the metal.

    FINISHING STEPS

    *Cut the sprues
    *Trim remaining metal from sprues
    *Clean up the inside of clasps and uprights with Taper Stone
    *Grind or trim tight areas with an Inverted Cone
    *Go over the entire case with a Small Barrel for polishing
    *Sandblast and prepare for polishing

    CONVENTIONAL ELECTROPOLISHING

    Use conventional electropolishing systems accepted and recommended for high-heat Chromium-Cobalt partial denture alloy only. Consult manufacturer's instructions and specifications for proper operating procedures. Rubber point all clasps and go over all surfaces that have been rubber wheeled.

    PRECAUTIONS

    When melting, grinding, or polishing alloy, use adequate ventilation, vacuum systems, protective eyewear, and protective masks and clothing.
