Quality Management

Our approach

The domains of the products and services of the Mitsui Kinzoku Group, which are rooted in the development of resources and the smelting business, are expanding from non-ferrous metals to various functional materials for the electronics and other industries, the manufacturing and assembly of functional parts for automobiles, the provision of technical services in the engineering business, and others.
We are pursuing the manufacture of safe, high-quality products that satisfy customers by establishing the Basic Quality Policy in 2012 as the standards for our resolute efforts to achieve quality in each business area and site in Japan and overseas.

Fundamental Quality Policy

[Philosophy]

The Mitsui Kinzoku group considers the voice of its customers to be an asset and as such uses this asset in our efforts to constantly ensure optimal quality. 

[Policy]

  1. We will anticipate the needs of our customers and proactively offer products and services that satisfy them.
  2. The quality of our products is a reflection of the quality of our work. Therefore, we place importance on the participation of all our members and on speed as we strive to raise our overall quality.
  3. In order to guarantee product quality, we adapt our quality assurance systems for each of our business areas and strive to refine our systems. 

This policy applies to all subsidiaries and facilities of the Mitsui Kinzoku group worldwide.

Strengthening of the quality assurance system

To strengthen the quality assurance system, Mitsui Kinzoku Group established the Quality Assurance Department on March 20, 2018. In addition, in order to strengthen quality assurance functions, we have promoted the independence of quality assurance departments in each business line, and have completed the construction of systems in all business divisions.
The Quality Assurance Department at the head office and the Technical Department and Quality Assurance Department of each business division make up the Quality Assurance Committee, which promotes planning and implementation of strengthening the quality assurance system.

Strengthening of the quality assurance system

Ensuring quality compliance

In fiscal 2018, the Quality Assurance Committee conducted a quality compliance survey at all 36 sites in Japan. At the same time, the committee conducted quality compliance training to raise awareness of quality compliance.
