As the fall semester for Purdue Polytechnic Institute rolled to a close earlier in December, students in the schoolβs capstone programs reached the half-way point on their efforts. Proportion-Air is sponsoring two capstone teams this school year.
Both teams visited the companyβs Indiana manufacturing facility in the fall semester, learning about manufacturing processes and asking questions to help them complete their projects.

For these students, the capstone program is two academic semesters, generally at the end of their undergraduate careers. They undertake a group project that showcases the knowledge theyβve gained throughout their programs. The teams are two of several capstone groups wrapping up their college careers at Purdue. In the program, they are named by their team number. Proportion-Airβs sponsored teams are numbers 15 and 16.
Team 15βs project is to improve the design of Burling Valve regulator, specifically to perform more effectively in superheated steam applications. The team includes three students from the Purdue Polytechnic Institute.
Vincent Zhi is a junior majoring in mechatronics engineering technology. Heβs the project leader and secretary for the team. A Chinese-American, he has spent half of his life in Shanghai, China, and half in Fremont, California.Β Christopher βRayβ Kurniawan comes to Purdue from Jakarta, Indonesia. He will graduate in 2024 with a degree in mechanical engineering technology. Kurniawan is the teamβs mechanical designer and process manager. Hunter Kepner of Fishers, Indiana, is a senior majoring in mechanical engineering technology. Heβs the scheduler, lead researcher and communication manager for Team 15.

The second Proportion-Air team, Team 16, is working on a project to create an acoustic sensor solution to provide proportional control for cylinder position without using a rod. Five students are working on this project.
Jason Ripper is a senior from Edelstein, Illinois, majoring in audio engineering. Heβs Team 16βs testing and validation manager. Jacob Nicholson is a mechanical engineering technology and automation and systems integration engineering technology major from Fort Wayne, Indiana. Nicholson is the mechanical design leader and manufacturing process manager. TJ Manifold of Rising Sun, Indiana, is a senior in electrical engineering technology. His role on the team is secretary and budget/cost manager. Nico Macchiavello of McLean, Virginia, is pursuing a double major in electrical & audio engineering technology with a certificate in music technology. Macchiavello is the project manager and electrical design lead. Carmel, Indianaβs Ian Cockrell is a senior in robotics engineering technology with a minor in electrical engineering technology. Heβs the manufacturing process manager.
