About TOPNC

Shanghai Top Numerical Control Technology Co., Ltd. (TOPNC) is a specialized provider of high-end intelligent manufacturing equipment and process solutions, primarily targeting the aerospace sector. The company was established on May 18, 2007, by a group of experts and PhDs in fields like mechanical manufacturing and automation, including Dr. Wang Yuhan, a former professor at Shanghai Jiao Tong University. The founding team was driven by the goal of localizing critical manufacturing technologies, particularly for advanced five-axis computer numerical control (CNC) machine tools, a market segment where China faced technological blockades.

TOPNC's business model revolves around the design, research and development, production, and sale of its specialized machinery. Its clientele consists of core enterprises within China's aerospace industry, such as AVIC entities (Chengfei, Xifei, Shenfei) and subsidiaries of the China Aerospace Science and Technology Corporation (CASC). The company's products have been integral to major national projects, including the Long March series of rockets and domestic aircraft programs. Revenue is generated from the sale of these high-value equipment systems and providing related services and process solutions.

The company's product portfolio is centered on advanced manufacturing hardware. Key offerings include five-axis linkage CNC machine tools, specialized aerospace assembly equipment, and comprehensive intelligent production lines. A significant achievement is the development of "mirror milling" technology, which addresses the complex challenge of precisely machining large, flexible components like aircraft skins. TOPNC has developed eight core product lines, featuring gantry five-axis machining centers, horizontal five-axis flip milling centers, and robotic drilling equipment. The company has received numerous accolades for its technological advancements, including the National Science and Technology Progress Award. After several attempts, the company is again pursuing an IPO, having filed an application in Hong Kong in May 2025.
