Tianjin Jingcheng Weiye Machinery Manufacturing Co., Ltd. has established strategic partnerships with numerous large steel enterprises both domestically and internationally. The HI3 mandrel semi-finished products are jointly manufactured by both parties, while the finished products undergo quenching and tempering in a controlled-atmosphere heat-treatment furnace operated by JCWY.
