Precision Injection Molded Flange Connector

Featuring a central cylindrical boss and an annular flange face, this component is commonly used in fluid pipeline connections, pneumatic element interfaces, or support and positioning scenarios for automation equipment. Typically serving as a transition connector, it utilizes the flange face for sealing or fixation, while the central bore allows for media flow or shaft passage. The bottom and side wall features are designed to配合 specific tooling for secure installation.

The part exhibits a uniform black matte finish, characteristic of engineered plastic injection molding. Materials typically include PA66, POM, or ABS—thermoplastics chosen for their strength and wear resistance. Key manufacturing controls focus on ensuring the coaxiality between the central inner hole and the outer flange, as well as the flatness of the flange mounting surface, to prevent wobble or leakage after assembly. Strict control over injection shrinkage is maintained to ensure dimensional consistency across batch production.

Our Changzhou factory boasts a mature non-standard parts manufacturing system, equipped with multiple 4-axis/5-axis machining centers from Shenyang Zhongjie and Tuobang. Although the illustrated part is an injection molded component, our robust supply chain and post-processing capabilities allow us to provide full-process services from mold development to final assembly. For such rotational parts, we can evaluate the need for secondary machining to correct critical tolerances or apply specific surface treatments for corrosion resistance and aesthetics, supporting flexible delivery modes for both low-volume/high-mix and high-volume/low-mix orders.
