Aiming at a harmony of people, technology and the environment


Since our foundation as a limited partnership Shirogane plating company in 1949, we have been offering plating products over many years.

The plastic plating technology that we have continued developing since 1966 has led the industry, answering client needs with reliable technology and high quality products. Because of the huge environmental impact the plating causes, we have made special efforts to implement measures for environmental protection through the introduction of solar systems, and the development of effluentfree treatment systems. With the introduction in 2015 of plating equipment that alleviate environmental loads, we have renovated our factory friendlier to the environment.

In order to keep up with ever-changing age, we integrated bases of business activities in the country at once place, and established systems that stabilize the production capacity and allow adapting ourselves promptly to needs of development and implementation of new technologies. We are determined to continue to challenge with the spirit of "aiming at a harmony of people, technology and the environment, and become a company that can swiftly respond to the new era", and contribute to society to become a company that is trusted and regarded as indispensable by society and thereby we intend to fulfill our social responsibility.
