Trace the evolution of Shandong Sunvim Motor from its foundational assembly lines in the early 1960s to its modern, high-tech industrial park system.
Gaomi Electric Appliance Factory is established, focusing on basic electrical motor repair, agricultural grids, and simple components. In 1988, this operational framework was formally renamed as Weifang Electric Machinery Factory, representing our first leap in regional market positioning.
Mr. Sun, then the forward-thinking factory director, left Gaomi Electric Appliance Factory to establish Gaomi Towel Factory. This crucial foundation served as the core predecessor of the modern multi-billion RMB Sunvim Group.
Weifang Electric Machinery Factory is successfully acquired by Sunvim Group. This merger allowed the establishment of Shandong Sunvim Electrical Machinery Co. Ltd., integrating advanced industrial management standards into the motor division.
A new, state-of-the-art facility is constructed in the Sunvim Industrial Park, and the company is officially renamed Shandong Sunvim Motor Co. Ltd. This modern hub integrates digital workflows and precision production tools to support global distribution.
