of facilities reported pouring alumi- num, iron and steel, and 120 facilities (7.5%) pour both aluminum and iron. Titanium remains in last place, with only 20 facilities casting it.


Process


Leader: Horizontally-Parted Green Sand Last Place: V-Process


Horizontally parted green sand molding is the perennial favorite process, with 647 (or 40% of facili- ties) using it. Its vertically-parted counterpart is used by only 14% of facilities. The nobake process comes in a close second at 610 facilities, or 38%. Many facilities report using


multiple processes. One hundred twenty-one facilities use both the green sand and permanent mold processes (8%), and 441 facilities use both the green sand and nobake processes (28%). Only six facilities reported using the V-process.


Plants Per State


Leader: Ohio Last Place: Alaska (note: some states have no metalcasting facilities) Ohio leads the industry in number of metalcasting facili- ties, with 155 (or 10% of the total facilities in the U.S.). Pennsylvania is the runner up, with 127 facili- ties, followed closely by California, with 124. Wisconsin, Illinois and Michigan round out the top six, each with more than 100 metal- casting plants. Alaska has one metalcaster, and the other states with fewer than 10 facilities include Louisiana, Maryland, Maine, Mississippi, Nebraska, New Mexico, Nevada, South Dakota, West Virginia and Wyoming. 
