Case
Study:
Foundry Sand, McClanahan,
Hollidaysburg, PA, USA
IN BRIEF
| The 175 year
old McClanahan Corporation contracted with Macawber for the supply of 2
Sandpumps for the purpose of outfitting their foundry located in Hollidaysburg,
PA with a foundry core sand reclaim and recycle system. The plant engineer devised a plan that would
place 2 Macawber Sandpumps in service under silos for new and reclaimed foundry
sand. They changed from continuously
using 100% new mould sand, to an 80/20 new/recycled mix, which has translated
into a significant operational savings.
McClanahan has been in business since 1835 and the site where we
installed our Sandpumps happens to be a civil war era building site which has
been in McClanahan ownership since before the war. Macawber application engineers and field
tech’s worked with McClanahan engineers to devise a system to collect and
separate re-usable mould sand and save considerable expense in both purchasing
special mold sand and paying material disposal fees. The systems have been operating continuously
now since installation in June of 2007. |
