R&D
Our continued R&D investments are reinforcing our future competitiveness.
Our R&D is largely divided into our own technology development activities, and industry-university cooperative ventures with external academic research institutions. As far as our own technology development activities are concerned, in 1994 we announced our goal of ‘developing advanced technologies to gain a competitive edge,’ and have since continuously invested in technological innovation. Our investments have born fruit and we continue to develop new technologies every year.
As for the industry-university cooperative R&D activities, we have been working with both Aju University and Chungju National University to continuously develop new technologies and apply them to our production facilities.
As a result of KPF’s R&D efforts our technical expertise is widely recognized as evidenced by the certifications we have been conferred by leading certification authorities and the patents we have been awarded. KPF was named one of the top 100 companies in Korea with the best quality competitiveness by the Agency for Technology and Standards. Our top-notch technical know-how was recognized once again.
