Precision Cast Connection Bracket

A connection component featuring a double-round-hole flange and irregularly shaped extension arms, designed to secure parts at different axes or angles via a central transition structure. Commonly used in linkage mechanisms of mechanical equipment, valve actuators, or automated transmission systems, this part serves as a critical load-bearing and positioning node. It ensures dimensional stability of hole spacing and mounting surfaces to meet assembly tolerance requirements.

The manufacturing process utilizes silica sol precision casting to achieve near-net shaping of complex geometries, effectively reducing subsequent machining allowances and improving material utilization. For the casting's internal cavities and mating surfaces, vertical machining centers are employed for drilling, tapping, and precision face milling, ensuring coaxiality and positional accuracy comply with drawing specifications. The factory is equipped with Coordinate Measuring Machines (CMM) and spectral analyzers to strictly control key dimensions and material composition, guaranteeing consistency in batch deliveries.

Leveraging Nanjing Dongkun's comprehensive manufacturing capabilities in precision casting and machining, we offer customized production in carbon steel, stainless steel, and alloy steel. We support one-stop services from mold development and rough casting to finished product surface treatments (such as sandblasting, electrophoresis, and galvanizing). Buyers can provide detailed 2D/3D drawings and technical requirements for us to assess process feasibility and formulate targeted machining and inspection plans.
