You can experience the joy of making things firsthand

Until now, I’ve worked in customer service, but I’m currently part of the casting team, where I’m involved in production management—including sales. While this work leaves a tangible legacy and I’m not actually involved in hands-on manufacturing myself, I feel a great sense of accomplishment when, through production management, I work with my teammates to repeatedly address failures and issues on the production floor, make improvements and adjustments, and ultimately deliver the finished product.
Furthermore, even today, the casting process still involves hand-molding and grinding each piece individually. This is because the shapes are streamlined and complex, making it impossible to mold and finish them without manual labor. There are many items in the world that can only be manufactured through casting, and I believe this is a valuable technique that will remain unchanged for years to come.

I feel that a sense of fulfillment in one’s work is something you discover as you go along.
Although we live in an increasingly digital world, manufacturing has a depth to it, and because the results are tangible, I think you can experience a sense of fun and accomplishment—even though it’s an “analog” process. Good luck with your job search.
