Investment Casting – Smart Process Technology & Control Jim Byrne, VA Technology Ltd., 2015 Innovator of the Year Booth 324/326 Advanced Technologies continue the march through the Investment Casting process .... exciting technologies provide the platform for enhanced process control and competitive cost reduction. Advances in Smart technology provide the process stability to enable higher process yields and output productivity. These same process benefi ts have enabled a whole new segment of opportunity to manifest itself in the form of very large shell production. Keeping the IC industry ahead of competing processes demands that the quest to employ evermore innovative and benefi cial solutions must continue within our industry. With focus on the Shellroom and Finishing Dept, the paper will provide technical details of the most advanced systems control in operation, with input from end users and ceramic materials suppliers on the key benefi ts of the system. The paper will also communicate how the process technology developments are greatly expanding the total dimensional envelope and capacity available from the Investment casting process.

Transforming the Special to the Common: A Methodology to Remove Special Cause Variation from the Investment Casting Process Julie Markee, Key Process Innovations, ICI Director Cliff Fisher, Wisconsin Precision Casting
A process is defi ned as being in control when the only source of variation is common cause.
Through the use of statistical process control, a
manufacturer can review production data and determine when common and special cause variations are at work in the process. W. Edwards Deming estimated that 94% of all process variation is a result of common causes while 6% could be attributed to special causes. It is the identifi cation and elimination of special cause variation that leads to a predictable, stable process output resulting in reduced scrap, improved product fl ow through the plant and increased profi tability. Some examples of special cause variation include injecting the wrong parts for a specifi c order, damaging wax dies or heats with the wrong chemistry. However, some special cause variations are subtler and require a methodology in order to identify, monitor and control key input variable(s). This paper will present a methodology for identifying sources of special cause variation along with systems which can be implemented to reduce or eliminate these issues resulting in improved process stability. A case study conducted with Wisconsin Precision Castings will be presented demonstrating the use of this methodology to identify and reduce variation within the investment casting process.
2:20 p.m. - 3:00 p.m. Paper No. 12
Improved Drying Effi ciency in Lost Wax Molds and Reduced Drying Time in Plaster Molds Using Microwave Norio Chida, Takumi Kotani, Japan High Comm, Booth 123 The technical paper at the 2012 ICI technical conference by Japan High Comm (JHC) presented that we developed an innovative proprietary technology to dry lost wax molds using microwave including microwave drying chamber and a complete shell making line with incorporation of it. It has been put into practical use and now they are practically applied at some leading foundries worldwide. The technical paper in 2013 then presented JHC microwave effectively dries molds with complicated cavities with combination use of supplemental drying mechanism, which optimizes drying effi ciency, and it allows molds to be drastically dried in short time.

been repeatedly conducted to this day, and it has demonstrated JHC microwave is also capable to dry molds with strict technical requirements in short time. Some of its results were presented at the 14th World Conference in Investment Casting in April 2016. This JHC microwave mold drying system is not only an effective way of reducing drying time, but also effective for reducing lead time of new product development period, improving prototype yield rate, and saving energy costs.
