We generally judge the quality of hardware buttons in this way, color fastness to rubbing; uniform shape; good release smoothness of the button body, smooth cavity; fine workmanship... Such buttons are good quality buttons. Of course, buttons made of different materials (such as resin buttons and shell buttons, etc.) have different standards for distinguishing the quality of buttons. For example, for hardware buttons, many people will weigh them to understand the "gold content".

Hardware button inspection methods and requirements and standards:

1. Control sample or confirm sample. See if the color and model match the sample;

2. There should be no cracks, notches, unevenness and obvious scratches on the button surface;

3. No car cracks and bubbles on the face and back; no rotten edges and uneven thickness;

4. The pattern should have no obvious deformation, no white eyes, white circles and other phenomena;

5. The buttonholes should be smooth and unobstructed; the needleholes are all worn and broken, and should be symmetrical and without big eyes. If it is a dark eye button, the dark eye groove should be smooth without obvious cracking.

6. After electroplating or other processes, the effect should be uniform. If some special effects cannot be consistent, they can be packaged separately.

7. The color difference of the buttons in the same batch should not be lower than the gb250 grade 4 standard, and compared with the incoming sample, it should not be lower than the gb250 grade 3 standard.

8. Packaging inspection, after the appearance inspection/customer required performance test are all qualified, and then sub-package. Certificates of conformity or other labels should be placed in the packaging. The number of packages should be consistent with the regulations, and the actual number of each bag should be consistent with the specified number. If it is found that the thickness exceeds the tolerance due to different thicknesses or other reasons, all inspections are required.

9. The emergency button/car hood button/five-claw button should be tested before delivery to test the button performance and usability, and provide mold and test samples to customers.
