  1. A cylindrical billet of a preferred aluminum alloy is subjected to varied temperature ranges between 800°F to 925°F. The ideal temperature is dependent on the specific aluminum grade you are using.
  2. After the billet heats up, the operator transfers it to a loader. The operator makes sure specialized lubricant film is added to the billet to avert adhesion to machine, handle and ram.
  3. The billet moves to the cradle, where the machine’s ram exerts reasonable pressure on the dummy block.
    It results in pushing of the aluminum billet into the container through the die.
  1. The billet gradually crushes against the die and progressively conforms to the triangular shape and set size.
    While at it, liquid nitrogen flows around the die sections, thus cooling it to an appropriate temperature. This creates an inert atmosphere and prevents formation of oxides on extrusion, thus increasing its durability.
  1. Aluminum extrusion part flows onto runout table in a similar shape as the die cavity.
    At this point, the extruded part elongates and is directed to cooling table for the fans to speed up cooling process.
  1. Once cooling is over, the piece is transferred to a stretcher for straightening and work hardening operations.
  2. Straightened and hardened aluminum triangle profiles are moved to saw table for cutting the pieces into desired dimensions.
  3. The pieces are heat-treated in ovens for further hardening and quickening of the aging process. In essence, this enhances stability, durability and increases longevity of the end project or structure.
