Aluminum is put into the crucible and heated to 660oC until is molten. A degassing tablet is put in to help all the impurities separate from the pure aluminium. The cope and drag, with the mould inside the sand, is placed underneath the crucible. The molten aluminium is poured into the runner until it comes out of the riser.

Heat 1 of 3- Investment Casting of Steel in the research foundry at Missouri University of Science & Technology. I’m the person controlling the furnace and turning the wheel on the ladle.

I had a problem with the steel not wanting to go into the shell mold part way through. After we stood around bored for a couple seconds, we finally gave up.

Heat 2 of 3- Investment Casting of Steel in the research foundry at Missouri University of Science & Technology. I’m the person controlling the furnace and turning the wheel on the ladle.

In addition to making castings, we were also taking thermal readings from inside the first shell mold. You can see the white insulation running out of the container, which was used to protect the wires.

This one happens to include a segment at the end with Simon talking to me about proper ladle orientation while moving.

PART THREE – Sand Casting Process with Philip White and Jenny Dunseath in the foundry at Camberwell college of Art London. Video by Chris Follows part of the Process Arts Project – http://itrdu1.arts.ac.uk/wpmu/process – University of the arts London

Text Information supplied by Jenny Dunseath:

11. Take Cope off and set it aside. You should be able to see an imprint of your Pattern. Depending on its location use your hole-cutter and cut a Sprue hole by placing your hand on the back of the Cope and push hole cutter through the other side, twisting slightly.
12. Widen the Sprue hole on the top of the Cope, to enable the metal to flow. Ensure all edges are smoothed and there is no loose sand.
13. Tap on the Pattern to loosen, use a screw to take Pattern out.

14. With a set of Bellows blow out all loose sand, make sure everything is smooth.
15. Place your flask back together and pour your metal!
16. After pouring wait for the material to solidify. The amount of time this takes will depend on the size and density of the piece of metal you are creating. Large, dense pieces of metal will take more time to solidify than smaller pieces.

The crane operator gets a bit disoriented, but we managed.

The ending has one of Simon’s stories, but the person recording cut it off. Be thankful for that.
