■Core Competence

Sannouriken has provided its core mass-produced products (850,000/year in 2006), hard chrome rods and plated shafts, to a number of customers in Chubu, Kanto, and Kansai areas.
The plating industry requires one of so-called 3K work conditions (“Kitsui (tough),” “Kitanai (dirty),” and “Kiken (dangerous)”) and is not necessary environment-friendly.
Sannouriken will respond to customer needs by acquiring Environment ISO certification as well as providing stable products to numerous customers with proactive automation.
