Company information
Ehime Prefecture, where I live, has long been a region with a high production of mandarins. As it is said that a cardboard box is synonymous with a mandarin box, the demand for cardboard manufacturing and sealing machines has been proportional to mandarin production, and at the same time, there has been a demand for their design. Focusing on this, we decided to start "Daiwa Design Co., Ltd." on June 1, 1982, which specializes in outsourced design for machinery manufacturing companies. We undertook numerous designs, and revisions of drawings and product testing were repeatedly conducted on the manufacturing company's site. A quarter of a century has passed, and during this time, we were compelled to conclude that the integration of manufacturing and design is now essential for perfect drawings and perfect products. Thus, on December 12, 1990, "Daiwa Engineering Co., Ltd.," an internal manufacturing division that engineers exterior lines for all industries, including food, pharmaceuticals, cosmetics, and electronics, was born.
