As early as from 1997, Robinson Shao joined Jiangsu High Hope Wuxi Company. From then on, the growing business and respectable personality of Mr. Robinson Shao made possible the consolidation of their activity and the incorporation of new and stable suppliers. In 2007, Robinson Shao founded Wuxi Friendship International (WFI). The company started being the agent in China for many international clients who produced essential oils and aroma chemicals for the flavours and fragrance industry, and we handles metal forging, casting, welding, machining, heat treatment and other fabrication and installation. Going back to our roots, the group is taking its wealth of professional knowledge from long years of practice incorporating it into a new philosophy of every co-operation. Robust, rigid and versatile, our CNC series will accommodate everything from light to heavy machining, from easy to complicated structure. With WFI on your side, you gain direct access to the people, technology, and ideas you need to capture opportunities and position your business for the future. Single-source simplicity means the responsibility for answers and support rests entirely with us, period. So instead of excuses, you benefit from a wealth of resources and refreshing peace of mind. A lasting commitment from us and long-term solutions for you. That is WFI and that is a motion to push forward.
