lost 20% of gray iron sales, but we have more than made that up in ductile.” MGIF also produces a number of
specialty irons, including high-silicon- molybdenum, austempered ductile and compacted graphite iron (CGI). Largely on the strength of the company’s ingot mold production (it is the country’s largest producer of the castings), CGI makes up as much as 10% of MGIF’s business. But that doesn’t mean the company will ever lose its gray iron business, according to Schipper. “The higher end stuff is the bread and butter, but the gray iron is a good
solid material,” he said. “We need that solid gray base to pay the light bill. It is very stable.”
CGI and Quality Go Hand in Hand Peaslee enjoys building beyond
MGIF’s stable base of gray iron. He becomes excited when talking about its “sil-moly” and takes pride in his com- pany’s ability to produce CGI without the help of contracted services. “We control our sulfurs and every-
thing else so tightly,” he said. “We control them to the third decimal point. We pour wonderful CGI.”
try is diverse sources of scrap,” said Steve Matthies, quality control manager. “We’re not tied into alloy components that a lot of people run into with their steels. We can run lower residuals and produce ductile with better properties than many [other] producers.” The company also has been able to
elevate its quality due to several of the improvements it has made in the past year. The dust recycling system it installed has allowed it to achieve higher compres- sion strengths and lower compactabilities with the use of less bond in its green sand system. The automatic molding machine also has afforded it advantages. “The [automatic] machine gives us a
little more fl exibility, and it is running with less scrap,” Matthies said. “It has replaced [an aging machine], and we have adapted most of our squeezer patterns to that machine.”
Going Forward MGIF wasn’t alone in having a ban-
