AFS Twin Cities Chapter welcomes Randy Oehrlein, VP of Engineering at Carley Foundry Inc, to the monthly meeting on Tuesday January 9th, 2019 at the Green Mill in Plymouth, Minnesota with the Social beginning at 3:00pm. Randy’s presentation on “Quantifying Casting Quality Through Filling Conditions” will begin at 4:15pm.

About the Speaker… Randy Oehrlein has a BS in Mechanical Engineering from the U of M and an AA from the Saint Paul Technical College in Design Technology. He currently serves on the AFS 2E Permanent Mold Committee, AFS 2D Structural Castings Committee, AFS Casting Congress technical papers review, and in addition reviews technical papers for the International Journal of Metal Casting. He has participated in AFS sponsored research as both an investigator and steering committee member along with serving on the AFS Research Board for 5 years. Randy has given presentations for the AFS Casting Congress or specialty conferences for molten metal transfer, semi permanent mold technology, thermal management of permanent molds, and energy reduction in a jobbing foundry. Randy also serves as an instructor for the AFS permanent mold courses and contributed to the AFS aluminum casting in-house training material and online courses. Randy contributed chapters to, and facilitated the completion of the AFS Handbook of Permanent Mold Casting Technology as well as a contributor to AFS Aluminum Casting Technology Handbook and Casting Defect Handbook. He is the recipient of the 2007 AFS Glen Stahl Service Award recipient, the 2009 William Frishmuth Aluminum Foundryman of the Year award, and the 2014 AFS Scientific Merit Award.

About the Topic… Randy will present findings on a recent AFS research project where multiple foundries produced the same castings to the same process, although using three distinctly different gating systems. The castings were also poured in four different alloys. The castings were then inspected for quality with X-ray, Liquid Penetrant Testing, pressure tightness, computed tomography scanning, fracture analysis along with mechanical property testing. The results were surprising in many cases and may change how we think about the relation of gating systems and part quality.
