Mechanical Engineering Expertise in Hydraulic Drill Parts Manufacturing
Our CEO, Mr. Cha, is a machinist and engineer as well who has a degree in Mechanical Engineering. He has over 30 years of experience in the machining industry, starting his own factory in 1999. He also has extensive knowledge about the mechanism of hydraulic rock drills, and this has enabled us to acquire two patents for the damping system (shock wave absorption system) in the rock drill with the Korean Intellectual Property Office.
