Nickel plating is widely used not only for industrial applications but also as a base for various types of plating due to its excellent adhesion to various metal substrates. There are many types of baths available, and by selecting according to the purpose, optimal properties can be achieved. While there is a high degree of freedom in combinations, Kamiyari Ken has four basic types that it handles. 【Nickel Strike Plating】 Dull nickel plating (1 layer). Used as a base for various platings. Essential as a pre-treatment for plating on stainless steel. ■ Functional Characteristics Decorative / Rust prevention / Conductivity Diffusion prevention / Low-stress coating 【Bright Nickel Plating (1 layer)】 Bright nickel plating (1 layer). Elegant appearance with a glossy finish. Widely used for washers and bolts. ■ Functional Characteristics Decorative / Rust prevention / Conductivity Diffusion prevention / Low-stress coating 【Double Nickel Plating】 Semi-bright + bright nickel plating (2 layers).

In the chrome plating process, environmentally harmful hexavalent chromium, lead alloy electrodes, and perfluorosulfonic acid are used; however, Kamiya Riken aims to reduce the environmental impact of the chrome plating process by utilizing low-environmental-impact conductive diamond electrodes as a substitute for lead alloy electrodes. Conductive diamond electrodes have high oxidative power and excellent chemical stability, making them a promising alternative to lead alloy electrodes. Through joint research with local research institutions such as Shizuoka University and other companies, it has been discovered that conductive diamond electrodes can be used as a substitute for lead alloy electrodes, and efforts are currently underway to put this into practical use. [Our Role] ■ In the course of developing this joint research, we evaluated the electrochemical properties of conductive diamond electrodes. *For more details, please refer to the PDF document or feel free to contact us.*

A major manufacturer consulted us about wanting to transfer the plating process for concert xylophones and glockenspiels. Since we had the same type of plating bath, it seemed to have a lower hurdle compared to transferring it to another company. However, we found that there were differences in the metal content of the plating film, making it impossible to create a process that matched perfectly. Therefore, we conducted trials under various conditions. After several rounds of prototypes, we were able to establish a process that was comparable to the one before the transfer. [Challenges] ■ Wanting to transfer the plating process for concert xylophones and glockenspiels ■ Differences in the metal content of the plating film made it impossible to create a perfectly matching process ■ There were parts where combinations not typically used were employed *For more details, please refer to the related links or feel free to contact us.

• Plating Equipment

The customer's request was for a "hard surface treatment that can withstand harsh environments." Our company proposed "hard chrome plating," which boasts exceptional hardness among plating treatments. Since welding is performed in a later process, it was necessary to leave certain areas unplated, requiring specialized equipment. Therefore, we simultaneously developed and installed dedicated jigs, masking methods, and a dedicated line, successfully establishing a system to stably supply the requested plating treatment. [Case Overview] ■ Request: Hard surface treatment that can withstand harsh environments ■ Solution: - Proposed "hard chrome plating," which boasts exceptional hardness among plating treatments - Simultaneously developed and installed dedicated jigs, masking methods, and a dedicated line *For more details, please refer to the related links or feel free to contact us.
