For cost reduction, improved yield, increased durability, and extended lifespan! Surface treatment using our unique ionized vapor deposition method to accommodate coatings of various dimensions!
We provide surface treatment tailored to customer needs with DLC and ICF coatings that help reduce costs, save energy, enhance durability, and improve lifespan, from small sample prototypes to large-scale contract manufacturing. DLC-Hard coating is a standard DLC formed by our unique ionized deposition method, demonstrating an overwhelmingly low friction coefficient compared to other hard thin film coatings, along with high hardness, excellent anti-adhesion, wear resistance, and low aggressiveness. We accommodate coatings of all dimensions, from small diameter pins to large rolls. As the applications of DLC thin films expand, there is a need for the classification of DLC thin film properties by physical characteristics for specific applications. To clarify this classification, we introduce the concept of ICF (Intrinsic Carbon Film), which redefines DLC within a broader framework. ICF refers to carbon films with high functionality, including DLC. By developing our unique DLC coating technology and performing various doping and structural control on DLC, we have successfully imparted various high functionalities. *For more details, please contact us or refer to our catalog.

Company information
We established Nanotech Co., Ltd. in 1989, pursuing our dreams in the technologies of "plasma" and "vacuum." Currently, we are developing coating technologies, including DLC (diamond-like carbon), using these technologies. Many of the DLC coating technologies are applied to drills, molds, and machine parts, making them a vital technology that supports the industry behind the scenes. I believe that Japan's status as a "technology-oriented nation" is due to the existence of such remarkable technologies that are not immediately visible, which lead to the creation of high-performance, high-quality products. To meet our customers' needs over the long term, enhancing our internal systems is key, and the ideas and actions of the people working here create a vibrant corporate culture that fosters reliable responses to our customers. We are currently focusing on creating this environment as our top priority.
