Given the thin‑wall and dense‑hole characteristics of the filter switch housing, we adopt high‑speed CNC equipment paired with custom damping fixtures to effectively mitigate vibration‑induced deformation during machining. Our engineering team is deeply involved in DFM design reviews, optimizing machining paths while preserving structural strength, so as to improve dimensional consistency and assembly accuracy of components.
Optical‑grade surface inspection: SQE engineers implement full‑process quality control. A colorimeter is used to test the mat‑anodizing performance of the switch housing, ensuring inner walls are free of reflection, burrs and bright spots to fully satisfy stringent optical imaging requirements.
Full‑dimensional digital management: Hexagon Coordinate Measuring Machines (CMM) and vision measuring instruments are deployed for 100‑percent‑coverage sampling inspection on key positional and geometric tolerances of every batch. Detailed inspection reports are provided to enable full‑traceable quality assurance.
