"Coexistence of machinery and beauty" surface treatment
Nihon Denko Kogyo Co., Ltd. is a company that specializes in small-lot production, handling a wide variety of products. We propose and provide optimal specifications from the base layer to the finish according to applications and needs. The ability to handle important one-of-a-kind items, prototypes, and small-lot mass-produced products, which are difficult for large-scale production factories to manage, is due to our reliance on manual labor rather than machines. We also accommodate special plating such as partial and two-color plating, as well as build-up plating. 【Specialized Technologies】 ○ Thick Plating Gold, silver, and palladium-nickel plating can be applied up to 100μm thick. The finish is aesthetically pleasing, and other types of plating can also be applied thickly. ○ Metal Allergy Countermeasures and Environmental Regulation Compliance We offer plating specifications that do not contain nickel, which is a cause of metal allergies. Nickel-free gold and silver plating is possible on stainless steel materials. We also comply with regulations such as RoHS and REACH. ○ WET & DRY We can perform a combination of wet and dry plating, such as ion plating on the surface of the plating, in-house.
