共栄精工 List of Products and Services

We combine over 50 years of accumulated knowledge in metal processing technology and conveying systems, as well as metal materials, to manufacture equipment using the hot rolling method. Based on cold rolling technology, we have successfully developed a hot rolling technique with higher expansion efficiency. The difference between cold and hot rolling lies in the percentage of expansion possible, with hot rolling allowing for a greater percentage of pipe expansion. To perform hot rolling, it is not sufficient to only develop processing equipment; we also need to select the metal material itself, manage the temperature and time during heating accurately through batch furnace management technology, and have the expertise to transport high-temperature workpieces, requiring a comprehensive and integrated approach to manufacturing. 【Features】 ■ Control of feed speed and roll position through NC feeding ■ Can be placed directly without digging a pit ■ Fully automated ■ Independently driven double rolls ■ Improved roundness and processing accuracy ■ Measures against chips and scale ■ Improved material yield ■ Various workpiece shapes For more details, please download the catalog or contact us.
