Commitment to craftsmanship

Features of Nihon Dento Kougyo

Reliable technology that boasts to the world

Using the abundant plating solutions and our cultivated technological capabilities, we propose and provide the optimum specifications, from the base material to the finished products which match the customer's application and needs.

Responding to various functions and finishes

In 1958, we succeeded in developing a high-speed alloy thick gold plating method that surpassed the technical standards of Europe and the United States. We have over 50 types of plating solutions including about 20 types plating solutions, which have been developed in-house.

From research projects to mass production

We handle everything from prototypes to mass production. In addition, we also conduct the required tests and analysis.

  • Thick plating

    Gold, silver and palladium-nickel plating can be thickened up to 100 μm.

  • Plating of materials which are difficult to be plated.

    Direct gold plating on stainless steel materials and plating of the materials those are considered difficult to plate are possible.

  • Countermeasures against metal allergies and compliance with environmental regulations

    We support plating that do not contain nickel to avoid metal allergies. Nickel-free gold and silver plating are possible on the stainless steel. We also comply with the RoHS Directive and REACH Regulations.


『 Finesse & Technology as one 』

To surface treatment with higher added value

We have obtained ISO9001 and ISO14001 certification. Since Nippon Dento Kougyo processes everything manually, we can respond to the detailed customer requests (plating specifications, film thickness, etc. and the specific requirement). We accept everything from a single prototype/development project to large/small lot mass production. In addition, it is also possible to analyze the material and surface condition. If you have any problems with surface treatment, such as being rejected by other companies, having trouble with a problem, or particular type of plating, please contact Nihon Dento Kougyo!

Plating possibilities are endless! Let's become successors to open up the future with world-class technology!
