GW Precision Technology Co., Ltd. is a China-based steel spool manufacturer focusing on steel spools for aluminum rolling, aluminum foil rolling, annealing, repair and lifecycle service.

GW Precision Technology completed a comparative impact test between a conventional steel sleeve and a metallurgical remelting steel sleeve to evaluate surface performance improvement. Through hardness testing and practical impact verification, the test demonstrated enhanced surface hardness and improved resistance to impact deformation of the metallurgical remelting steel sleeve. The solution is designed for demanding applications in cold rolling mills, foil rolling mills, and rolling mill spare parts.
