Environment RoHS: Restricting the use of Hazardous Substances

Denkahimakukougyou is focused on the development and support of eco-friendly products.
We follow Green Procurement Guidelines of leading manufacturers and have acquired the ECO-Action 21 certificate from the Ministry of Environment of Japan. To ensure compliance with RoHS directives, we take proper measures to control chemical substances, and offer RoHS compliant products.

Examples
Aluminum chemical conversion treatment
Trivalent chrome processing and hexavalent-chrome-free processing are also available.

Black chrome (BCr)
We are capable of applying a process designed specifically to make coating hexavalent-chrome-free, as there is a chance that remaining hexavalent chrome in coatings can exceed its threshold level (1000ppm). If this process is required, please request a RoHS compliant or low-hexavalent-chrome product. Standard applications of our product may contain remaining hexavalent chrome levels over 1000pm.
