The SungJin staff is fully equipped to engineer and manufacture the products through the utilization of advanced manufacturing tools and programs (Six Sigma and SPC) and other diagnostic methods of design and manufacturing.

Recognized by the Korean Government as “the most innovative small business company in the Republic of Korea”, we have been positioning ourselves as the premier exporter by obtaining additional certifications with many distinguished registers such as CE, UL, VDE and TUV.
