Non-cyanide silver plating bath using no cyanide - Dine Silver Series

A non-cyanide, strongly acidic silver plating process that does not use any cyanide compounds.

This is a strong acidic non-cyanide electroplating process based on organic acids. It allows for silver plating without etching the resist pattern and direct silver plating on SUS materials. It consists of two processes: strike silver plating and main silver plating. By adjusting the bath composition, it can be applied to various plating methods, including rack plating and continuous plating. Depending on the application, options for a matte white, semi-gloss white, or glossy appearance lineup are available.

Non-cyanide silver plating solution "Dine Silver"

Silver plating has been valued since ancient times for its unique hue and has been widely used in decorative items alongside gold. It is still utilized today in decorative accessories, tableware, medals, and more. Furthermore, silver boasts the best electrical and thermal conductivity among metals, a reflectivity close to 100% in the visible light spectrum, and excellent oxidation resistance, making it suitable for a wide range of applications including various lead frames, electrical contacts, and reflectors for functional plating. Plating processes involve the use of various chemicals, some of which include harmful substances like lead, mercury, and cadmium that can impact human health and the environment. Toxic cyanide compounds are also used in silver plating. Yamato Chemical Research Institute has developed the world's first practical "non-cyanide silver plating solution" that allows for the safe and secure use of silver's excellent properties without cyanide. This environmentally friendly non-cyanide plating solution from Yamato Chemical is called "Dine Silver." *For more details, please refer to the related links below.*

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
