Harvey Mudd Students Lauded for Manufacturing Innovation

In late 2016, Purosil LLC, a silicone hose manufacturer in Corona, California, was losing revenue and customers on their formed hose product line. In an effort to change course, the company reached out to Professor Kash Gokli and 无忧视频 engineering students, hoping that their knowledge of modern manufacturing practices and their innovative ideas might be the answer. That turned out to be the correct decision: Within a year, the students had helped Purosil employees implement a new way of manufacturing that increased production and efficiency and boosted revenue by $3.1 million annually.

The students, juniors Ankoor Apte, Bohan Gao, Giulia Castleberg and Rachel Perley, and their advisor, engineering professor Kash Gokli, won the Manufacturer鈥檚 Council of the Inland Empire Innovation Award for their work with Purosil. The award was presented in February at the MCIE鈥檚 2018 Manufacturers鈥� Summit.

鈥淚 was so proud of them,鈥� says Gokli, professor of manufacturing practice and Engineering Clinic director. 鈥淪tudents can think out of the box. They believe anything is possible.鈥�

With funding from the Henry E. and Gayle Riggs Fellowship in Engineering Management, a team of students worked at Purosil part-time over two semesters, doing research to determine the source of the company鈥檚 problems. Apte, Gao, Castleberg and Perley then spent 10 weeks in summer 2017 working full time at Purosil, implementing their proposed solutions.

鈥淲hen I walked in to the factory, it was not what I expected,鈥� says Gao, who witnessed a lot of time and productivity being lost as employees tried to navigate a disorganized environment. 鈥淚t鈥檚 exciting to see that our work over 10 weeks got it closer to the ideal.鈥�

In addition to updating the company鈥檚 manufacturing processes, the students faced what was perhaps a bigger challenge, recasting the employees鈥� method of information flow or 鈥渢ribal knowledge,鈥� as Gokli describes it.

The students put together a simulation to show employees how making some changes would improve their workflow and efficiency. For example, they automated the paper filing system and some other manual operations. Now, anyone can access up-to-date designs via a tabletop monitor and computerized files. Once people saw the ways lean manufacturing principles could improve their productivity and workflow, Gao says, there was a noticeable change in morale as well, even for those employees who had to make big changes.

鈥淭he thing about lean manufacturing is that it鈥檚 hard to change people鈥檚 habits,鈥� he says. 鈥淲e expected resistance, but it turned out to not be that bad as long as we communicated well. That鈥檚 the point when we felt like the work was rewarding. We see the human impact and see that they become happy because our work is helping them out.鈥�

This is the second collaboration between Harvey Mudd students and Purosil, and there is potential for more. With each project, Gokli has two objectives: 鈥渢hat we make companies more competitive by transforming their manufacturing and that our students learn a lot,鈥� he says.
