Hard Coating

Surface modification technology has a long history of development, over the past years in a variety of industries with different application requirements for film layers. Among them, vacuum coated film has always been one of the key technologies in scientific and technological development. The development of vacuum coated nano-grade hard films can meet the wide range of demands in an environment friendly way to reduce costs and increase productivity. Additionally, vacuum coating technology can improve the surface properties of objects, and provide workpieces with enhanced features that increase product value reducing friction, enhancing wear/corrosion resistance, and prolong the service life of the workpiece.


DAHYOUNG is the leader in advanced thin film technology in Taiwan and supports high-end hard coating technology to allow customers to obtain the best surface treatment solutions.
