Hardware buttons: open size mold (existing mold repair) ->open button surface mold (shape)/pattern mold (logo/pattern, etc.) ->trial mold, sample production ->roughening embryo ->oil washing/polishing ->electroplating ->other process treatments (oil painting/laser/silk screen, etc.) ->inspection/testing ->packaging and shipping
Alloy buttons: draw design drawings -->carve copper -->Electrical discharge machining -->bulk molds -->test molds -->roughcast -->polishing/hand polishing -->electroplating -->other process treatment (oiling/laser/silk screen, etc.) -->inspection/testing -->packaging and delivery
Inspection requirements and standards:
1. Reference samples or confirmation samples. Check if the color and model match the sample;
2. The surface of the button should not have cracks, notches, unevenness, or obvious scratches;
3. No car cracks or bubbles on the back of the face; No rotten edges or uneven thickness;
4. The pattern should have no obvious deformation, white eyes, white circles, or other phenomena;
5. The buttonholes should be smooth and unobstructed; The needle eye should be symmetrical and without large eyes, and should not be punctured or ruptured. If it is a blind eye buckle, the blind eye groove should be smooth and free from obvious cracks.
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 buttons in the same batch should not be lower than the GB250 fourth level standard, and compared with the incoming sample, it should not be lower than the GB250 third level standard.
8. Packaging inspection is carried out after the appearance inspection/customer's required performance test are all qualified before repackaging. When packaging, a certificate of conformity or other label should be placed. The quantity of packages shall be consistent with the regulations, and the actual quantity of each bag shall be consistent with the regulations. If it is found that the thickness is different or other reasons exceed the tolerance, it shall be inspected in full.
9. The emergency button/hood button/five claw button should be tested for performance and usability before shipment, and mold and trial samples should be provided to the customer.
