<div class="moz-cite-prefix">My son works in a local foundry here in
California. Pollution controls are actually not a big issue for
them, they do specialized steel castings, largely for the
technology companies. Back in the 1980s I had a fascinating
conversation with the managers of the foundry that made the
Sprinkler pipe fittings and parts that I preferred. They said that
their main issue as far as emissions was visible water vapor. This
was because it was an Aluminum foundry and they used a combination
of clean metal and their own scrap to create the castings. The
water vapor visibility made people think that they were polluting!
Now, the ubiquity of pollution control technology has brought down
the cost and complexity of installations unless there are paint or
other contaminations of the metals....</div>
<div class="moz-cite-prefix"> I also found that when I bought
planter plates for my Ventura Bean planters that were made after
about 1980 that they are now aluminum alloy rather than iron
because of the lower cost of small batches of aluminum parts than
cast iron low grade materials....</div>

<p>I was speaking with an acquaintance this morning who teaches
Material Engineering at Cal Poly SLO. I asked about his recent
trip to Iowa, did six weeks a NIU? Apparently he teaches
casting, probably from the metallurgical standpoint. He
mentioned he had visited several foundries in the area, JD and
affiliated, I assume. With the recent discussion on casting
parts here I got interested. Didn’t have time to elaborate,
but I did find out that there are 57 foundries in California.
Hard to imagine with all the pollution controls. <o:p></o:p></p>
