material into the mold. Since we are forcing more material into a constant volume, the pressure was much larger than the original. There was an average increase in pressure of approximately 40 MPa. See Figure 2. Figure 2. Thickness & Weight vs. Shot Size When we decreased the Pack/Hold time, the pressures decreased as the time decreased. We assume that our first data point in an outlier, our data follows this trend. The weight and the thicknesses are approximately the same as the original. See Figure 3. Figure 3. Thickness &Weight vs. Pack/Hold Time From our data, there are no significant changes or patterns that one can see from changing cooling times. This would be intuitive because we are not changing the amount of material but rather the time that the mold is held together. See Figure 4.

Figure 4. Thickness &Weight vs. Cooling time As the Pack/Hold pressure increased the weight increased, and the pressure increased. As pressure increased, the force pushing material into the mold as it cooled increased, this increases the weight. As the amount of material filling a constant volume increases, the pressure increases as well. See Figure 5.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
