Abstract: Strain gauge bases (Flexors) are scarce in the Mechanical Engineering Department. Flexors are used for MET lab classes to collect and analyze data so it is important for there to be more Flexors available. In order to acquire more, resources are available on campus such as the foundry and the machine shop in order to support the manufacturing of more Flexors in-house at a much lower cost. By creating a pattern that can be used numerous times in a foundry, not only will there be an opportunity to make more castings for students to use, there will not be …

In the green sand molding process olivine sand is compacted into flasks that are used for the molding and pouring process in a foundry. These sands are difficult to remove after the pour has been made. In Central Washington University’s foundry the sands are currently being removed with handheld rams. To improve on this process a Foundry Flask Punch Out machine was designed. The machine was designed to utilize a wall mounted rack and pinion style press. The supporting elements of both the flask and press were engineered with deflection requirements in mind. The machine was made to fit into …
Tabletop Die Cast System, Brad C. Barringer
Tabletop Die Cast System, Brad C. Barringer
All Undergraduate Projects
The project was to design, manufacture, and test a tabletop die cast system to be used as lab equipment in MET 257 – Casting Processes. The motivation for this project was the MET 257 – Casting Processes instructor’s desire to physically demonstrate the die casting process, but they were unable to find a system that would meet all of their requirements. They required a system design that was small, portable, would fit in the foundries limited space, had an open concept to allow students to see what was occurring during the pour, and compatibility with the foundries current equipment. The …
Conversion Casting: Adapter Hub, Joseph M. Coup
Conversion Casting: Adapter Hub, Joseph M. Coup
All Undergraduate Projects
The concept of conversion casting makes manufacturing major components much more efficient with regards to time and cost. The conversion cast of the adapter hub used in the Victair Mistifier is a major component that requires 8 hours to machine. The existing hub starts from steel stock and then that block of steel is placed into a CNC machine and coded in to create the adapter hub. The manufacturing method changes to a casting for the adapter hub will create a replicated part that requires 1.5 hours of post machining. The intricate design makes a conversion to casting more effective …
