Most common type of defects related to Mechanical Parts and Assembly quality control in China
- Inaccurate or Faulty Calibration: Measurement tools and instruments that are not properly calibrated, leading to inaccurate measurements and potential deviations from the desired specifications.
- Assembly Errors: Mistakes during the assembly process, such as incorrect sequence, omission of parts, or improper alignment, which can impact functionality, performance, and reliability.
- Electrical or Wiring Issues: Faulty electrical connections, improper wiring, or insufficient insulation, which can lead to electrical failures, short circuits, or malfunctions.
- Dimensional Deviations: Components that do not meet the specified dimensions or tolerances, resulting in improper fitment or functionality.
- Surface Imperfections: Flaws on the surface of the parts, such as scratches, dents, pits, or rough finishes, which can affect aesthetics or compromise performance.
- Misalignments: Improper alignment or positioning of components, leading to assembly issues, misfits, or mechanical failures.
- Material Defects: Flaws or inconsistencies in the material used for manufacturing, such as cracks, voids, inclusions, or weak spots, which can affect the strength and integrity of the parts.
