At present, most of the screw screws need to be plated, and now electroplating factory plating products are more, many products are mixed together for plating, if the number of screws and screws, electroplating plants will pack different specifications of the screw screw Together with the plating, it is easy to cause some screws screw plating less, or poor plating and even cause some screws screw deformation, scrapped. If the screw cross the slot before plating is not cleaned, then the plating may not be able to cross the slot plating.

The following circumstances should not be with the hard with, so as not to affect the screw product quality.

1, in the conventional plating process conditions difficult to meet the different aspects of the screw plating quality requirements. In the case of

2, the hardware screw size is too close, size, large and the length of the tail wire seems almost all. This kind of metal screws are scribed and plated. Or else when the plating is good, not bad points ah, screening is not good.

3, relatively heavy screws and relatively light screws, relatively small screws and relatively large screws to score the plating. Or else there may be two in the plating process which will encounter, resulting in damage to the screws.

4, easy to plug the two screws should be separated from the plating. Otherwise the two different specifications and models of the screws stuck together, when the plating into a ball. Easily lead to electroplating. Even after plating, it is difficult for us to separate these two types of screws.
