Foundry Sand
IN BRIEF
A 175 year old 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. The customer 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 the customer’s ownership since before the war. Macawber application engineers and field tech’s worked with the customer’s 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.
