Engineering Plastic Gears and Copper Alloy Flanges

We provide custom non-standard structural components, including green helical gears and brass disc flanges, tailored for assembly needs in transmission systems and fluid control modules. These parts are typically used for power transmission, positioning support, or as insulating isolation layers in mechanical equipment. The core focus is on ensuring gear meshing precision and the coaxiality of mounting holes to guarantee smooth operation and sealing performance.

Our manufacturing process emphasizes the synergistic control of material properties and dimensional tolerances. For engineering plastic gears, we mitigate internal stress deformation during injection molding or machining to ensure tooth surface finish and module accuracy. For metal flanges, we prioritize end-face flatness and the positional tolerance of multi-hole distributions. Using Zeiss 2D and CMM inspection equipment, we perform 100% inspection of key mating dimensions to effectively prevent assembly interference caused by tolerance accumulation.

Leveraging Dongguan Kai'an Plastics' inventory of over 30 types of imported engineering plastics such as PEEK, PVDF, and POM, along with precision processing equipment like turn-mill centers and engraving machines, we offer one-stop services from material selection to final delivery. Whether for single-piece prototype validation or small-batch, high-variety production, we flexibly adjust process solutions according to drawing requirements to meet the stringent standards of the automation, semiconductor, and environmental protection equipment industries.
