Metal screw plating is environmentally friendly and non-environmental. Environmentally friendly plating has environmentally friendly blue zinc, environmentally friendly color zinc, environmentally friendly black zinc, environmentally friendly white zinc, environmentally friendly nickel, etc. Non-environmental: white zinc, color zinc, black zinc, blue zinc , nickel, etc. Everyone also understands that there are many electroplating factories and electroplating products. Many products are mixed together. If the number of screws we have is relatively small.
Under normal circumstances, the electroplating factory will mix and match our different specifications of screws. In this case, it is easy to cause some screws to be not plated, or poor plating or even some screw deformation, scrapped.
Especially our combination screw, because it is a combination of three pieces. Inside and out, it's not so good for plating. Also, if the cross recess of the screw is not cleaned before plating, the plating may not be able to plate the cross recess. It should be based on the experience accumulated on a daily basis, and should not be reluctant. The following situations should not be rigidly matched to avoid affecting the quality of the screw product.
