CI Kougyou Co., Ltd.

We are a manufacturer of special resin products used for cosmic ray measurement, which have been adopted by customers in Japan and overseas. 

Our company develops, manufactures, and sells special resin products (plastic scintillators) used for measuring cosmic rays. Over 5,000 units have been sold to universities and research institutions. These include University of Tokyo Cosmic Ray Research Institute, High Energy Accelerator Research Organization, Japan Atomic Energy Research Institute, Nagoya University, Maritime Safety Agency, Institute of Space and Astronautical Science. Our products have also been sold to overseas organizations including University of California Lawrence Berkeley Laboratory, National Institute of Geophysics and Volcanology (Italy), University of Tasmania, and University of Adelaide. Our partner manufacturer network helps us satisfy a diverse range of needs. We also have manufacturing machines and materials on our premises to deliver in a short period of time. 


Other presentation

[Company strength]
The diversity of our partner network helps us satisfy a wide range of needs. We can also satisfy needs for quick deliveries by making use of the machines and materials on our premises. 

[Business description]
Our company manufactures and sells special resin for cosmic ray measurement (plastic scintillators), and designs and manufacture derived resin and metal parts. We also design and manufacture measuring devices, implements, and equipment for use in nuclear experiments. 


[Strength of products/technologies]
We can make the exact product for your needs in the field of plastic scintillators. This is because they are manufactured in our company. Some of our products took more than two years to develop, but we have sold over 5,000 units to universities and research institutions in Japan and overseas. Our products are made through extrusion molding, so the manufacturing cost can be much lower than ordinary scintillators depending on the quantity. We recommend twist-type light guide products. These have been made possible by applying uniform bending technology developed by our company (the guide thickness remains the same even on the curved side). 

[Representative's message]
We want to promote the use of our original cosmic ray plastic scintillators in new fields by publicizing their extensive use by our current domestic Japanese and overseas users. We have been delivering a wide range of products made-to-order by skilled craftsmen for over 40 years to universities and research institutions in various fields. We will continue to improve our technologies so as to satisfy customer needs. 

[Company structure for market development/overseas expansion]
We currently focus on manufacturing and sales of thin plastic scintillators in cooperation with a plastic (acryl) manufacturer. We hope to start catalog sales by the end of the year.
