Coatings that support manufacturing! They are used in a wide range of industries.
"DLC" stands for "Diamond Like Carbon," which is a surface treatment technology that involves coating a thin film primarily composed of carbon onto surfaces such as metals. It is widely adopted across various industries as a coating that supports manufacturing, including cutting tools, molds, automotive parts, machine components, and medical parts. DLC, which features a mixture of structures like diamond and graphite, is harder and has better lubricity compared to common ceramic coatings such as titanium-based or chromium-based coatings, and it excels in properties like "wear resistance" and "adhesion resistance to non-ferrous metals." 【Features】 ■ Film thickness of a few microns ■ Available in a range of hardness (1000–7000 Hv) ■ Excellent lubricity *For more details, please refer to the related links or feel free to contact us.

basic information
【Other Features】 - The way carbon bonds allows for high hardness of 7000Hv (AC-X). - The entire structure is amorphous (similar to glass), excelling in lubricity and smoothness. - Being primarily composed of carbon, it has excellent non-affinity with non-ferrous metals, making it less prone to adhesion, welding, and seizure. - Low hardness DLC tends to cause fewer scratches and wear on counterpart materials during friction. - Chemically inert, it is resistant to rust and does not easily degrade in corrosive environments. - The ratio of graphite structure to diamond structure, along with the content of hydrogen and metals, influences its conductivity or insulation tendencies. - As it is made from carbon, it has minimal impact on the human body. *For more details, please refer to the related links or feel free to contact us.

Company information
Onward Giken is an expert company that specializes in contract processing for surface treatments such as DLC and ceramic coatings. 【Pioneers in DLC Film Development with High Technology for Both Equipment and Films】 In 1986, we were among the first in Japan to introduce film deposition equipment, and in 2001, we completed our own developed DLC equipment. Since then, we have continued to develop new films and now handle a variety of coatings, including 13 types of ceramic films and 8 types of DLC films, with numerous patents obtained. 【Development Technology + Years of Experience + 21 Types of Films = Onward's Proposal Power】 At Onward Giken, we propose the most suitable film for our customers from over 21 types of coatings based on our self-developed "film deposition technology" and the data obtained from more than 30 years of extensive "experience." First, our sales representatives listen to the customer's needs and the issues they want to solve, and then our internal team analyzes them. Additionally, with the support of the Technology Development Research Department responsible for equipment development, we consider solutions across all departments to address the customer's problems. 【Support for Development Prototypes and Small Lots from One Item】 Orders of 5 items or fewer per lot account for 79% of our total orders. We also regularly handle orders starting from one item. We are happy to accept inquiries from universities and companies regarding development projects.
