Preliminary Agenda Abstracts


course of an initial validation in an industrial environment, a German Foundry has produced more than 40,000 wax parts (turbocharger wheel) completely free of release agents. Other pilot customers are already using the coating successfully and profitably in series production.


11:20 a.m. – 11:50 a.m. Investigation on Permeability Measurement Method of Investment Casting Shell Molds and Influencing Factors on Permeability Ryosuke Naito, IHI Corporation


Shell mold management is important to improve the stability of the investment casting process and their production. The permeability of shell molds is an important factor because it affects shell molds cracking while dewaxing, shell dry time, and smoother run of metal in shell molds. Permeability has been measured by various methods


in the investment casting industry. In the Ceramics Testing Guidebook by ICI, three permeability measurement methods are introduced. However, there are rooms for improvement for permeability measurement accuracy and stability. In the Japanese industrial standard (JIS), a permeability measurement method for ceramic materials is introduced. They are used for various ceramics such as bricks or concrete materials. There is a possibility to improve accuracy and stability of permeability measurement by the JIS method. However, this method is currently not applicable for investment casting shell molds. In this study, a sample preparation process and sample shape are checked to apply the JIS method for shell molds. Then, a relationship between shell conditions and permeability values is studied.


11:50 a.m. – 12:30 p.m. LUNCH - Disneyland South Ballroom


12:30 p.m. – 1:00 p.m. Development of Non-Contact Automation for Investment Castings Tim Ruland, Chris Tinker, Alexander Hautanen, Hitchiner Manufacturing, Inc. Josh Sullivan, Capture 3D One of the advances in technology for Hitchiner is the


progression of Structured Light and the growth of non-contact measurement systems. Coordinate Measuring Machine (CMM) use has been the main measurement tool for Production and Engineering, but the evolution of Structured Light has now become a dedicated staple. This growth in non-contact technology has merged into a fully automated resource and is still growing. Hitchiner’s usage of non-contact technology has been a continuous development initiative in serving the high demands of more complex aerospace products, research, and development within the company. The focus of this presentation will show a timeline growth within the last decade of utilizing new technology integration

1:00 p.m. – 1:45 p.m. How It Is Made – Ceramic Shell Raw Materials Produced by The Fusion Process Michael Weissenbacher, IMERYS The investment casting technology is used to produce high quality parts for very demanding applications, like automotive, industrial gas turbines, medicine or aerospace. To fulfill the very demanding requirements of the final casting, all components need to be produced under the highest standards and strict quality controls. This paper describes the production of fused raw materials used for the ceramic shells, in particular fused alumina, silica, and stabilized zirconia. The paper will address the different routes through which these materials are produced, how they will further be processed and the characteristics of the final products. The paper will demonstrate how the arc furnace and tilting technology can be used to obtain a variety of products with very specific properties, and how this beneficially affects the quality and performance of investment casting shells and thus the quality of the finished casting part. Finally, the paper will discuss current efforts to reduce energy consumption and carbon dioxide emissions in the production of fused minerals that contribute to our company’s sustainability targets for the benefit of our customers and stakeholders.
