Founded in 1988 as Daedeok Machinery, DDM began as a manufacturing-focused company. During this period, we accumulated core machining and component know-how, establishing the technical foundation that still defines our products today.

Starting in 2009, DDM experienced collaboration with external manufacturing partners. This phase was not about sourcing volume, but about technical comparison. We analyzed process-based durability differences, material behavior, and post-installation failure patterns. This period shaped DDM’s ability to define what constitutes reliable technology.

With technical standards established, DDM expanded operations through facility relocation in 2015. Growth during this stage was driven by field-proven performance in the domestic market. Our technology was repeatedly selected by repair shops because it reduced rework and improved reliability..

In 2019, DDM transitioned into a corporate entity to manage technology systematically. We secured two patents and achieved Venture Company Certification in 2021. This marked the shift from individual expertise to structured, documented corporate technology.

Rather than rushing exports, DDM focused on meeting international requirements. In 2024, we obtained FTA export certification for propeller shafts, along with ISO 9001 and ESG-based management systems. In 2025, we completed expansion into a new facility to support the next phase of growth..
