AFS/CMI NEWS Research Advances
Core Modeling AFS-sponsored research on the development of core vent- ing design guidelines recently was completed. T e research was conducted by Flow Science Inc., Leland, N.C., Alchem- cast LLC, Birmingham, Ala., and General Motors, Detroit. T e research program’s goal was to develop data for
binder systems in aluminum and iron casting, validate the numerical model in Flow3D software under this new set of casting conditions, and develop general core venting design guidelines for aluminum and iron. T e project provided a shop fl oor calculator and venting guidelines. T e research project was discussed in a panel, “Research Advances in Modeling,” at the 116th
Metalcasting Con-
gress. In addition to the research project, the panel detailed a program to estimate gas produced during casting in a chemically bonded core and compare it with the available metallostatic head of the metal to prevent gas defects. T e program also can be used to identify cores that require vent- ing in aluminum and iron castings.
New Partnership to Improve Manufacturing Skills AFS and its Cast Metals Institute have become the fi rst
Allied Association Partner of the Manufacturing Institute, a sister organization of the National Association of Manufacturers (NAM). T e partnership has three primary objectives: 1. Recruit the younger generation into manufacturing roles.
2. Encourage the use of and align new certifi cation programs with the NAM-Endorsed Manufacturing Skills Certifi cation System.
3. Foster partnerships between companies and educa- tional institutions (universities, high schools and grade schools) to ensure the right curriculum is being used to prepare students with the appropriate skills.
“T e metalcasting industry plays a vital role in the supply of
engineered components to many sectors of manufacturing,” said Jennifer Head, director of education, Cast Metals Institute. “We are excited to join forces with the Manufacturing Institute in support of the NAM-Endorsed Manufacturing Skills Certifi ca- tion System. T rough this partnership, we will work to address the shortage of skilled workers through the recruitment of tal- ented individuals and the development of metalcasting-specifi c certifi cation programs that align with the system.” T e 2011 Skills Gap Report, written by the Manufacturing
Institute, showed manufacturers are experiencing a moderate to serious shortage in skilled workers, including machinists, technicians and engineers. T e trend is expected to con- tinue and increase in coming years. Based on the trend, the Manufacturing Institute sought leading industry associations, including AFS, to advocate skill certifi cation.
