Many products are mixed together. If we have a relatively small number of screws. Under normal circumstances, the electroplating factory will mix our screws of different specifications together for electroplating. In this case, it is easy to cause some screws to fail to be plated, or poorly plated, or even cause some screws to be deformed and scrapped. Especially our combination screw, because it is a combination of three pieces. Inside and out, it’s a bit bad for plating. In addition, if the cross groove of the screw is not cleaned before plating, the plating may not be able to plate the cross groove. It should be matched according to the experience accumulated in daily life, not reluctantly. The following situations should not be rigidly matched, so as not to affect the quality of screw products. |
