AFS NEWS Molding Committee Provides
Audits to Casting Facilities Te AFS 4M Green Sand Committee traveled to Indianapolis in October 2013 for its quarterly committee meeting and Adopt-a-Foundry tour. Te mission of the 4M committee is to study all phases of green sand mold production, including both conventional and high-pressure (high density) production techniques, with an emphasis on achieving high-quality cast surfaces and the establishment of tolerance guidelines. One of the ways it achieves this mis- sion is with its Adopt-a-Foundry program, which involves visits to a member foundry to audit its green sand system. In the most recent audit, committee members were divided into three groups to focus attention on the plant’s prepared sand, shakeout and testing. Each group was given a tour of the facility’s sand testing lab, metallurgy lab, sand storage, core and molding lines, green sand catacombs, and melting and pouring departments. Common casting defects and sand issues were discussed with each group as well. At the conclusion of the tour, each group presented its findings and recommendations for improvement to the foundry’s personnel. Suggestions included eliminating the use of an extra muller, incorporating more moisture to eliminate burnout and bringing in a full-time sand lab tech- nician. Te committee compiles its findings into a written report that is submitted to the foundry. If your metalcasting facility is in need of a green sand audit,

AFS Issues Call for Research
Proposals on Sand Casting Te New Generation Sand Casting Consortium (New- Gen) has issued a call for white paper research proposals. Te NewGen Consortium, co-sponsored by AFS and
the National Industrial Sand Association (NISA), was formed to coordinate new sand casting technology develop- ment efforts toward producing sand castings with thinner walls, greater dimensional stability and accuracy, reduction in variability and improved repeatability. NewGen is asking for fresh thinking toward improving
green sand casting and chemically bonded core and mold technologies. Of particular interest are projects leading toward better control of green sand systems, real-time sand property measurement, computer modeling programs for sand systems and improved predictive tools. Also of high interest are new technologies and research related to the use of nonstandard sand materials, sand adhesion (binder) technology, refractory coatings and sand additives. For more information on the NewGen consortium, desired
research focus or to submit a white paper, visit the NewGen website at
www.afsinc.org/newgensand, or contact Steve Robison, AFS senior technical director, at
srobison@afsinc.org (800-537-42137 x227 or 847-824-1081x227).
