    Miyachi Unitek's Parent Company
    Miyachi Corporation (MHC), based in Tokyo, Japan, was established in 1972 to manufacture and market semiconductor-related measuring instruments and welding control equipment in response to the demand for quality control in the automobile and electronics industries. The company was quick to incorporate microprocessors and other electronic devices into its resistance welders to enable high quality precision joining and the monitoring and analysis of that process. Its Weld Checkers quickly became the worldwide standard for weld monitoring

    In 1984, MHC developed an Nd:YAG laser welder that allowed for more precise and micro welding, and this line has become one of the company's main business pillars along with resistance welding. In recent years, it has advanced into the laser marking arena with its Nd:YAG and Nd:YV04 laser markers being among the smallest and most powerful in the world.

    In addition to its subsidiaries in the US and Europe, the company has sales and manufacturing facilities in China and Korea. MHC is publicly listed on the Tokyo stock exchange.
