With a total of 2 patents to his name, Isomura's work showcases innovative methods that enhance the functionality and aesthetic appeal of resin materials.

Latest Patents

Isomura's latest patents include a method for producing a black plated resin part. This method involves electroplating a resin substrate that has an underlying plating layer in a trivalent chromium plating bath containing thiocyanic acid. The process results in the formation of a black chromium plating layer composed of trivalent chromium, which has a thickness of 0.15 μm or more. Additionally, the resin substrate is immersed in warm water at 30°C or higher for a predetermined time. The parameters of thiocyanic acid concentration, warm water temperature, and immersion time are carefully adjusted to achieve a black chromium plating layer that exhibits a b* value of -1.7 or less based on the L*a*b* color system.

Another patent focuses on the black plated resin part itself, which consists of a resin substrate, an underlying plating layer, and a black chromium plating layer. This layer is formed of trivalent chromium and also has a thickness of 0.15 μm or more. The chromium in this layer is present in the form of metallic chromium, chromium oxide, and chromium hydroxide, with the black chromium plating layer exhibiting a b* value of 3.0 or less based on the L*a*b* color system.
