Greeting

We’ve spent years improving our skills and quality since our founding in 1961 so that we can make contributions to society through plastic molding.
In addition to handling a wide variety of materials for thermosetting plastics and thermoplastic plastics, we’re utilizing the plastic molding know-how we’ve built up until now in the fields where we excel, such as insert molding and the manufacture of ultraprecision components. Additionally, in 1998, we took these plastic molding skills to the next level with the start of our optical communication connector manufacturing, and the Nissin Kasei brand is currently sold globally through export.
Today, the world is changing at an unprecedented speed. And we in manufacturing need to solve the difficult issues that come along with this, such as precision, complexity, high quality and using unfamiliar materials as substitutes. We’re aiming to be a company that can contribute to the solving of these issues with our plastic molding skills, and are working to innovate these skills every day.
We’re going to keep working so that our skills can contribute to the realization of products for our customers and so that they will be of use in the creation of abundant society. We hope to continue receiving your support moving forward.
