1:00 p.m. - 1:40 p.m. Paper No. 5 A Fundamental Analysis Into The Temperature of Investment Casting Slurries: Is it Important and How Can it Affect My Slurries? Gavin Dooley, Remet UK, Ltd. Foundries around the world measure temperature on
a daily or weekly basis as part of good slurry control. However, little is ever known or discussed about the impact of temperature on the performance of a slurry or a shell at different running temperatures. This paper aims to investigate the following questions:
Where is the heat generated? How does it affect slurry control? Does it affect a shell’s performance? Temperature fluctuations can occur due to external environmental conditions, equipment operation, and other factors within the slurry. These changes may alter the rheological properties of the slurry, affecting its application, adhesion, and overall shell strength. By presenting fundamental research and experimental
data, this study enables process engineers to understand these sensitivities, optimize their processes, and implement better control strategies to enhance overall casting performance. A deeper understanding of thermal influences can lead to improved defect prevention, better process stability, and more consistent casting quality, ultimately benefiting production efficiency and cost-effectiveness in foundries worldwide.

1:40 p.m. - 2:20 p.m. Paper No. 6 Faster Drying Layers or Fewer Layers to Dry – Which Shell-Building Approach Is Best For My Process? Azhar Juhari, Remet UK, Ltd. A time-consuming part of the investment casting process
is often the drying time of the ceramic shell created around the wax pattern, which can take several days depending on the slurry composition and drying conditions. Using ceramic slurries that either build thicker or dry quicker can decrease the time required for mold preparation, speeding up the casting cycle. This paper compares the two shell-building approaches
and aims to learn more about the advantages and disadvantages of each. Flexural testing, permeability studies, and dynamic mechanical analysis are employed to study the effects of each method on the resulting mold and determine once and for all which of the two allows for faster mold creation.
