Production and Production sites

Rigorous and clean manufacturing environment supported by DAIKYO innovators, with minimal human intervention

We make products for the safe packaging and storage of medical pharmaceuticals that save lives all over the world. Therefore, the responsibility required of us is heavy, and under firm and strict control, we operate all of our own production sites utilizing robotization.
While the automated process prevents contamination and maintains high quality, it is the innovators of DAIKYO who carefully manage and improve these operations.

Clean rooms are classified according to the necessity of the manufacturing process. Together with constant daily "Kaizen" activities and based on ERM, we optimize our manufacturing environment.

Thorough foreign material control and strict, clean manufacturing environment through automation

For half a century, DAIKYO has been researching and developing "How to stably supply safe products" with the awareness that one small rubber stopper can impact human life. We are never satisfied with the current status, and continue to make improvements on a daily basis, even in small matters. Our philosophy to create products that are useful to people, which began as a small factory in a small town, continues to be lit in the hearts of each and every one of our SMEs, even as we have gained a large share of the global market.

High quality is only possible through time, effort, and thorough attention to the obvious.

Komei Tsukiji,
Director, General Manager of Production

Efforts to improve product quality are based on thorough verification and control of work procedures and work environment.
The goal is achieved only when high-quality products are completed through a series of time-consuming and labor-intensive processes. We believe that those who are able to continue and thoroughly implement these measures are the ones who will be able to produce high-quality products.

Believing that small improvements can lead to a big effect.

Production technology department Production technology section Chief Katsumasa Goma

“The work of the Production Engineering Department covers a wide range of areas, one of which is the design and management of molds. The degree of perfection of a molded product is greatly influenced by the molds, so much so that it is said that “quality is 80% determined by the molds.
Therefore, our seemingly small improvements can have a big effect, and we tackle this difficult but rewarding job every day.”

Products that can be used with confidence not only in terms of the safety of materials but also in terms of the laws and regulations of each country.

Vice president of R&D Takuya Tanaka

From the selection of raw materials for new products to prototyping, evaluation, and intellectual property applications, we work in close cooperation with each department, taking into consideration global conditions and the laws and regulations of each country, not to mention the safety and security of our products.
In order to maintain the “Japan Quality” that we are proud of, we emphasize flat teamwork that allows everyone to think and act on their own.
Especially in recent years, we have been working on development with an awareness of sustainability.
