常光 Company Profile

If it's JOKOH. we can change the future.

One billionth of a meter is a nanometer. Nanotechnology exists in every aspect of the world. For example, cars. The interiors of new car doors being developed will be made of resin. This thin and strong resin is also made possible by nanotechnology. Our nano-milling technology creates nanoparticles by applying pressures that exceed those found at the bottom of the Japan Trench and speeds that surpass the speed of sound to materials. This leads to changes in new material properties. We will change the world with nanotechnology. By changing the world, we should be able to change the future. Our company will contribute to the future in the following three ways: "Contract Services," "Sales of Ultra-High Pressure Homogenizers," and "Joint Development of New Materials."

Business Activities

**History** We are a company engaged in the manufacturing and sales of medical devices. The "Nano Material Engineering Division" was established in 2007 and has since been involved in the design and sales of "ultra-high-pressure homogenizers," as well as obtaining patents related to technology and new material development. **Business** - Manufacturing and selling ultra-high-pressure homogenizers that disperse and refine all types of materials "uniformly." - Providing contract services utilizing ultra-high-pressure homogenizers. Mainly focusing on: - "Dispersion of carbon nanotubes" - "Exfoliation of graphene" - "Mixing of battery materials (anode and cathode)" - "Production of cellulose nanofibers" - "Dispersion of all-solid-state battery materials" - "Dispersion of conductive pastes and inks for electronics" - "Dispersion of metal-based materials" - "Emulsification of cosmetics" - "Crushing of pharmaceuticals sensitive to thermal changes" In recent years, we have received requests for contract testing from customers both domestically and internationally in various fields, as well as repeat requests (contract processing with a fixed monthly quantity). The "experience" accumulated from years of successes and failures is our company's "strength." Research, evaluation, and experimentation are conducted in cooperation with universities and research institutions both domestically and internationally.
