When the lost foam casting process initially gained recognition in the metalcasting industry in the 1970s and 80s, the manufacturing technology was far outpaced by the interest and motivation of the industry, resulting in the failures of many lost foam startups.
One of the areas that has been most improved by automation is building the lost foam clusters.
Guot's adjustment to his new life has gone remarkably well considering that the Lost
Boys, in the view of one authority who has worked extensively with refugees, were the most thoroughly traumatized group of people he had ever encountered.
Now, after nine years of subsisting on rationed corn mush and lentils and living largely ungoverned by adults, the Lost Boys of Sudan are coming to America.
The Lost Boys first survived a 6- to 10-week walk to Ethiopia, often subsisting on leaves and berries and the occasional boon of a warthog carcass.
Kelley's team identified these gases dissolved in the highly alkaline water that spouts from the Lost

I was reminded of this Muppet strategy when I went to see Michael Crichton and Steven Spielberg's latest mega-blockbuster, "The Lost
World," their admittedly shameless but highly popular clone of the phenomenally successful "Jurassic Park." Now it could be that I got a bad box of Raisinettes, but in the midst of this movie it occurred to me that, deep within the belly of this T-rex of a techno-thriller about replicant dinosaurs, there might well be a second and even more interesting film.
"When we sold the lost
foam casting facility, we knew we either could stay in the iron casting business and make a good living or we could find another way to grow the business," said Joe Robinson.
The supplied foams are attached to sprues at the plant to form the clusters, which then are robotically cooled and transported through one of two drying ovens to the lost
foam line where they are manually fed to a positioning device that lowers the cluster into the flask.
foam casting process is more susceptible to process changes than many similar processes because of the numerous critical variables and the complex interactions between them - which often are not fully understood.
However, there was a small increase in the lost
workdays incidence rate from 120.7 to 121.5.
