11:00 a.m. - 11:30 a.m. Improved Consistency of Slurry and Shell Properties using Particle Size Control of Ceramic Flours Tom Branscomb, Buntrock Industries Particle size distribution changes of ceramic flour can affect slurry properties including: slurry density, rheology, and coating thickness. Shell properties that can be affected are:
permeability, thickness,
edge coverage and strength. For critical applications like Titanium and DS/SC casting, control of particle size can mean the difference between success and failure. Methods and examples are presented on how to improve particle size control.
11:30 a.m. - 12:00 p.m. Autonomous Engineering Applied to Investment Casting Processes Gerald Richard, Magma Foundry Technologies Investment casting foundry engineers have been using casting process simulation tools to optimize casting designs and processes for years with the goal of finding the best compromise between casting quality and cost. Time is the most precious commodity in foundries and it is strictly limited by the number of skilled employees available, as well as the delivery requirements the customer demands. The time it takes to evaluate all potential options to finding the optimal casting process configuration by manually simulating them always exceeds the total time available. Autonomous optimization the main component of a new methodology called Autonomous Engineering, which is introduced by MAGMA® simulation tool MAGMASOFT®
majority of this “manual labor”. The software offers two autonomous optimization options, complementing, and potentially replacing, the traditional manual simulation option.

Process Control Standards Update Nipendra “Nip” Singh, S&A Consulting, ICI Director
1:30 p.m. - 2:00 p.m. Update on ICI-AFS Joint Research Project on MMPDS Inclusion of 17-4 PH and 15-5 PH Investment Cast Steels Jiten Shah, Product Development & Analysis (PDA) Al Torok, ICI Director, Yamaha Marine Precision Propellers Dr. Zayna Connor, AFS, Inc. Authors will give an update on this project which was presented at the last congress. Testing is undergoing for various tests as required by MMPDS using over 500 test plate castings and 600 cast integral test bars for a total of 3 different heat treatment types for each alloy per AMS specifications. Test plates were provided by 14 investment foundries, majority serving aerospace industry. The funding for the project was provided by DLA to AFS with in-kind cost share support from various participants.
