Internal Thread Flange Ring

As a critical transition component in fluid piping or mechanical transmission systems, this ring-shaped part achieves a secure threaded connection with outer pipes or shafts via its precision internal threads. Its structure features an internal threaded hole with clear tooth profiles and multi-step outer surfaces. It is commonly used for panel mounting, locking sensor bases, or sealing hydraulic and pneumatic joints, ensuring reliable connectivity under vibrating conditions.

The manufacturing process leverages the high-precision forming capabilities of CNC lathes, strictly controlling the pitch diameter tolerance and tooth profile regularity of the internal threads, as well as the coaxiality of the inner and outer cylindrical surfaces, to prevent assembly misalignment or seizing. For metal materials, the perpendicularity of the step surfaces and the smoothness of edge chamfers are rigorously controlled to avoid sharp edges that could damage sealing rings or injure operators. Mirror polishing or brushing treatments can be selected based on operational requirements to enhance corrosion resistance and aesthetic quality.

Equipped with multiple high-precision CNC lathes and Coordinate Measuring Machines (CMM), our factory supports full-process customization from single-piece prototyping to batch delivery based on 2D/3D drawings. Production strictly adheres to the ISO 9001 quality management system, providing material certificates and go/no-go gauge inspection reports to ensure that every batch meets the stringent standards of the petrochemical, medical device, and high-end equipment manufacturing industries in terms of thread fit precision and dimensional consistency.
