Embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of processing method of darkening ring, with reference to Fig. 1, in one embodiment, the processing of the darkening ring
Method includes the following steps：
Step S10, darkening ring is provided, the darkening ring includes body, coated on the anti-static coating on the body and
The through hole being formed on the body, the body are made of plastic material, and the anti-static coating is carbon dust layer, the through hole
By being stamped and formed out.
Specifically, in the present embodiment, the thickness of the darkening ring be 0.025 millimeter, a diameter of the 2.14 of the through hole
Millimeter, the body are made of polyethylene terephthalate.
Anti-static coating is coated since the manufacture of darkening ring is to be initially formed body, then in the outer surface of body, finally
Through hole is being formed on body by way of punching press, at this moment, the hole wall of the through hole is by polyethylene terephthalate
Formed, then machine can be corroded by aqueous slkali, and to form dumb light structure on hole wall, and the remainder of darkening ring is then
Covered with the anti-static coating formed by carbon dust layer, its susceptibility to aqueous slkali is poor, will not substantially be subject to aqueous slkali
Corrosion, and then ensure that the feasibility of this forwarding method.
Step S20, dumb light structure is formed on the hole wall of the through hole by alkali soluble corrosion.
Specifically, it is in the present embodiment, described to be formed by alkali soluble corrosion on the hole wall of the through hole with reference to Fig. 2
The step of dumb light structure, specifically includes：
Step S21, aqueous slkali is placed in supersonic generator.
