Our Advantages

For the future of factory automation, always offering optimum solutions

Since its establishment in 1952, DDK has been working for development, manufacture, and sales of products friendly both to people and the environment, as a pioneer of fastening systems. Specifically since 1975 when we first developed and manufactured electrical nutrunners, we have been promoting our technology innovation as a professional manufacturer of fastening systems, responding to global needs and contributing to the evolution of the industry overall.
In recent years, we have realized the total solutions in the press-fit and measurement fields based on the technology we have established in the fastening field. We have also taken on the challenges of new projects into the future, such as manufacturing synthetic sapphires for LEDs to help stop global warming and developing hydroponic cultivation facilities.
