"Plating with few pinholes and high adhesion" is a technology of Todenka Co., Ltd., which specializes in hoop plating and plating processing. Our various platings, represented by Ni plating, generate very fine metal particles that precipitate onto the metal of the product material. As a result, the meticulously plated surface has few gaps between the metal particles, making it difficult to form pinholes. This condition allows the plating to penetrate into the minute irregularities of the material surface, resulting in a very strong adhesion. Similarly, Sn plating achieves excellent solder wetting properties. *For more details, please refer to the catalog or feel free to contact us.*

"Continuous hoop plating on aluminum materials" is a technology that enables continuous hoop plating processing on aluminum coil materials and primary press-processed products (reel-to-reel), among others. Recently, with the soaring prices of raw materials such as copper alloys, using aluminum materials, which are relatively inexpensive and stable when material conversion is possible, offers significant cost advantages. Additionally, aluminum materials can achieve approximately three times the length of the same weight compared to copper alloys due to the difference in specific gravity, allowing for weight reduction that meets the needs of the lightweight and compact era. [Main Applications] ■ Bus bar materials for EV and PHV vehicles ■ Heat sink materials ■ Secondary battery terminal materials and enclosures for mobile phones, etc. *For more details, please refer to the catalog or feel free to contact us.
