PVT Dilatometer

During my last years of college, I developed a strong interest in mechanical design and subtractive manufacturing. I completed multiple CNC machining training sessions in Mexico and worked for several months as a CNC machinist to gain hands-on experience.

For my internship, I joined the Polymer Engineering Center at the University of Wisconsin-Madison to explore polymer science. My project involved developing a PVT Dilatometer to analyze the expansion (volume change) of polymer and blowing agent mixtures under varying pressure and temperature conditions. This research aimed to optimize formulations for plastic extrusion processes used in cosmetic product manufacturing.

This was my first experience conducting state-of-the-art research. I designed the apparatus, performed mechanical stress analysis using FMEA, and simulated heat transfer to validate the working principle. Alongside my research, I took as many machining courses as the Student Shop allowed, gaining additional hands-on skills. I personally sourced the materials and fabricated the device myself.

The project was a success—the device functioned as intended, and my work was well received. Professors were pleased with my contributions, and the machinist instructors were impressed by the level of dedication and craftsmanship I demonstrated. Beyond the technical aspects, my time in Madison was unforgettable. I made great friends, many of whom I still stay in touch with today.
