COTEC also provides a plant business that is related to manufacture processing facilities.

For IT industry, we have developed technologies such as magnesium anodizing and magnesium chromate for the first time in Korea. We have also developed the technology for a hologram with the glass substrate, which is currently applied to the plating of IT products.

For the nuclear power generation industry, we developed optimized chromium plating and other related technologies to acquire certification from GE. The technologies are applied to the hard chromium plating for the parts of nuclear power generation facilities.
For the aerospace industry, we have installed process lines to acquire quality-related approvals from Boeing in U.S.A. and SAFRAN in Europe; we have been also acquired AS9100/ISO9001 and NADCAP certifications. We have made a contract for the plating parts for the B787 aircraft series for the period of 2005-2008.

For the defense industry, we have constructed a dedicated facility for the chromium plating of large-diameter parts for the first time in Korea.

For the plant business, we have supplied defense-related plating equipments which previously had been supplied by overseas companies. We have also developed plating equipments and environment-related technologies.
With the research center founded in Jan. 2004, we have invested in developing new technologies related to the finishing of parts for defense and aerospace industry, database building and green environmental facilities.

With the efforts of 350 employees, we are planning to expand the processing lines to be the comprehensive surface treatment company with the world best technology by 2020.

The vision of COTEC in 21C is “the world best technology and quality”, which would be achieved by strengthening the human resources with the satisfaction of the employees on the basis of fulfillment of “Happy Family and Happy Company” and adequate training programs, securing technological excellence in surface treatment and establishing customer satisfaction through optimized processes for the needs.
