Shanghai Yan Yan Machinery Limited Company
Shanghai Yan Yan Machinery Limited Company is a China-based manufacturer with a long-standing focus on machine tool casting and milling castings production and processing. The company has developed capabilities in producing key machine tool components such as machine tool beds, columns, beams, sliding seats, rotary tables, and carriage boxes. Through the use of resin sand molding casting processes, the organization emphasizes producing castings with smooth appearances and small machining allowances, which supports high precision and efficient downstream processing.
The company has positioned itself as a supplier to many machine tool manufacturers, with a track record of supplying large machine tool castings and nodular iron components (such as HT200, HT250, HT300 and other ranges around 40 tons or below). This capacity is complemented by an established local advantage in Botou’s casting resources, along with a strong in-house processing and assembly capability.
Beginning in the 2000s, Shanghai Yan Yan Machinery Limited Company expanded its operations beyond casting into the machine tool production and assembly sector. Its portfolio includes CNC floor boring and milling machines, end milling machines, ground mobile double end milling machines, vertical column type double end milling machines, digital rotary worktables for planer milling machines, and large, heavy-duty long-bed milling machines and associated operations.
The company has cultivated relationships with numerous domestic enterprises, leveraging its casting quality, production speed, and processing precision to support the supply chain for machine tool manufacturers. By combining local casting resource advantages with robust machining and assembly capabilities, Shanghai Yan Yan Machinery Limited Company positions itself as a versatile partner for customers seeking integrated solutions from castings to finished machine tool components.
