AFS NEWS Division Notebook: Molding Methods and Materials Heavy on

Applied Research and Innovation Te AFS Molding Methods and

Materials Division 4 encompasses a large community of individuals in the metalcasting industry covers a large part of the actual casting process. Tis division has nine active technical committees: Executive/Paper & Programs (4A/4B), Publications (4A1) Honorary Awards & Nominating (4C), Mold-Metal Interface Reactions (4F), Foundry Sand Additives (4H), Cured Sand & Aggregate (4K), Investment Casting (4L), Green Sand Molding (4M), and Additives Manufac- turing For Metal Casting (AM4MC). Te division oversees research projects

that focus on innovative practices, ma- terials and methods of molding for the foundry industry. Te division currently has five funded research projects: • Application of Differential Scanning Calorimetry (DSC) with Gravimetric Analysis (TGA) and Mass Spectros- copy (MS) to Assess Sand Binder Emissions—University of Northern Iowa (4N)

• Reclamation of Investment Casting Shell Materials—Cal Poly (4L)

• Veining Reduction Project—Western Michigan University (4F)

• Improving Dimensional Accuracy of Castings from Silica and Molds— University of Northern Iowa

• Prediction of Gas Evolution from

Chemically Bonded Sand Molds Using Process Simulation Software— University of Northern Iowa Tese five research projects have the potential to provide the metalcast- ing industry with valuable knowledge on a variety of topics that involve the molding and core making processes. It is hoped that these projects will im- prove the foundry’s understanding of sand binder emissions, vein reductions, reclamation of investment casting materials, casting dimension accura- cies, and the evolution of gases from chemically bonded molds. Besides the five funded projects, the

division is monitoring one non-AFS funded research project, “Termal Property Trends in Green Sand,” from Saginaw Valley State University, which is under development. More projects are under consideration

for future funding: • Dynamic Green Sand Testing, West- ern Michigan University (4M, 4H)

• Advanced Green Sand Control, Penn- sylvania State University (4M, 4H)

• Termal Property Database from Investment Casting Shells, Missouri University of Science and Technology

• Prefiring Time/Temperature Effect on Investment Shells Termos- Mechanical

• Economical and Technical Feasibil- ity of Using Synthetic (non-Silica) Ceramic Aggregates as an Option for Silica Ruling Compliance, (4K and Division 10) Individual technical committee meetings are typically held three or four times annually and held primarily at AFS headquarters in Schaumburg, Illinois, although at times, committees will meet at various foundry locations. Tis change of venue often provides additional networking time between the committee members. Although each of the technical com- mittees is designed to focus on a primary topic, they are encouraged to go beyond the boundaries of their scope. Member- ship is composed of individuals from foundries, academia, equipment suppli- ers, and materials suppliers. Tis dynamic allow for valuable networking between individuals from varying principles and backgrounds. Without the AFS techni- cal committee community, many of these partnerships and collaborations would likely not occur. Te AFS technical committee structure provides them the avenue and vehicle to share and dissemi- nate this information. For more information about the divi-

sion’s activities and how to join, contact Laura Kasch at
