About DECA Corp

our promise

All of our executives and employees promise to supply products that meet our customers' needs. In order to do this, all of us will first maximize R&D capabilities by collaborating with multiple technology companies and investing in research and development. Dong-Ah has established its superior competitiveness in research and development by registering more than 200 patents and acquiring CMMI certification through our persistent interest and investment in ideas since the founding of the company. Second, we will do our best to diversify our market from domestic to overseas. With our experience and success in Korea, we are planing to expand our markets around the world. Finally, we will establish a Zero-Defect Quality Assurance System. Under the company slogan of "The quality is the value, not the price," we will build up the best quality-supply system, which offers defect-free products as perfectly managing the existing certificates such as QS9000, TS16949, ISO14001, Single PPM, and many others. In order to keep these promises, all members of Dong-Ah will demonstrate endless intention and motivation for creativeness and challenge. We will do our best to create better values for you by thinking about your position from the development stage, to the production and delivery of our product, and to the post-sales services in order to meet your demands.
