For products that require high wear resistance! Also compatible with partial plating using masking technology.
"Hard chrome plating" is applied in various fields as a functional plating with many mechanical properties. Its coating hardness can reach approximately Hv900 to 1000, making it particularly suitable for products that require high wear resistance. Additionally, it is possible to achieve a thickness of 0.1mm to 0.2mm, allowing for applications such as the repair of various components. Our company provides stable quality through a wealth of technical specifications, including unique tool know-how and masking techniques for partial plating that we have cultivated since our establishment. If you are facing challenges with hard chrome plating for precision parts that require relatively high accuracy, please feel free to consult us.

Company information
Surface treatment technologies, including plating, have continuously advanced and developed as familiar technologies in our daily lives. It is said that gold plating was applied to ancient decorative items, including the Great Buddha of Todai-ji in Nara. The pure desire to adorn objects more beautifully and to maintain that beauty forever has remained unchanged from ancient times to the present. Moreover, modern surface treatment technologies are not limited to purposes such as decoration and rust prevention; they are applied in various industrial uses. For example, many needs, such as wanting to harden the surface of a product, enhance conductivity, or reduce friction coefficients, can be achieved relatively cost-effectively through surface treatment technologies primarily based on plating. Since its establishment, Eputec Co., Ltd. has responded to various surface treatment needs of the times, consistently pursuing technological and production innovation. The key phrase is "Innovation for Tomorrow." Eputec Co., Ltd. will continue to respond to increasingly sophisticated and diversified needs and contribute to society as a "value-creating company" through surface treatment technologies that pave the way for tomorrow.
