Making work easier and absolutely safe for anyone : Case Study at Yumotokosan

Introduction Story | Seeking a Safe and User-Friendly Post-Processing Machine

Yumotokosan Co., Ltd., founded in 1960, originally produced wooden patterns for cast-metal parts. Leveraging these early technical skills, the company has grown into a comprehensive printing business, handling everything from printing and post-processing to assembling materials and shipping finished products. They specialize in thick paper and serve a variety of applications, including hanging display packages for home improvement retailers and packages for freeze-dried noodles.

For many years, they relied on an old manual die-cutting machine that lacked safety features and required advanced skills to operate. As a result, only President Yumoto himself could operate it. The company recognized the need for a safer, more stable production system that any staff could use with ease.

At that time, they learned about the AeroDieCut, which offers automatic paper feeding and is designed for safe and simple operation, and decided to adopt it.

A key reason for choosing AeroDieCut is that it can be safely operated by anyone. All the moving parts are fully covered and well protected, making it easy and safe to use, even for part-time or female staff. It also makes long, continuous jobs much easier, and being able to load the paper and simply press the start button allows operators to work even while seated.

Effect After Installation | Improved Productivity with Both Safety and Stability

The AeroDieCut is mainly used for processing hanging display packages for home improvement retailers. They have about five standard die boards and choose between the AeroDieCut and the old machine based on quantity. For small batches of around 500 sheets, they still use the old machine, while longer runs of over 3,000 sheets are handled by the AeroDieCut. Thanks to its automatic feeding system, workflow has been greatly streamlined, and tasks such as loading and unloading paper can now be done by general staff, not just skilled operators.

Previously, a time-consuming step called “patching”—a manual adjustment to ensure consistent quality—was often required. With the AeroDieCut, once initial settings are stored, the machine reproduces the same high-quality finish every time, regardless of who is operating it.

User Feedback | Less Manual Adjustment, Consistent Quality for Everyone

The AeroDieCut requires almost no adjustments, even when changing die boards. Unlike the old machine, fine adjustments are rarely needed, which greatly helps staff. It is also easy to operate, so even part-time employees can handle it confidently.

With the AeroDieCut, Yumotokosan has achieved stable quality, improved safety, and higher efficiency. By using both the old and new machines depending on application and lot size, they built a flexible and safer production system.
