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 Co., Ltd. provides steel spool solutions for aluminum foil rolling, annealing and lifecycle service, supporting stable structure, machining accuracy and practical spool-related problem solving.
In August, GW Precision organized a technical training session on steel sleeve products for all personnel of the Marketing Center. The training covered product applications, steel sleeves for aluminum foil and aluminum strip rolling mills, materials and heat treatment, and mechanical machining, with practical manufacturing experience and production cases included in the discussion
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.
