- Appearance inspection
Appearance inspection is one of the important methods for judging the quality of hardware accessories. Usually, the surface of hardware accessories should be checked for oxidation, scratches, rust, and other issues. At the same time, attention should be paid to checking whether the processing technology of hardware accessories is consistent.
- Dimensional inspection
Dimensional inspection is one of the necessary methods for quality inspection of hardware accessories. The sample size must be consistent with the size of the accessory. Dimensional inspection mainly includes outer diameter, inner diameter, height, width, length, etc., and professional measuring tools (such as micrometers, square rulers, etc.) should be used.
