What are the uses of etching processing

Etching processing Mainly for customized processing of metals, also known as metal corrosion processing, the applicable fields include electronics, precision hardware, communication, automotive engineering, medical, etc. So what are the specific uses of etching processing?

(1) Remove burrs. Due to the presence of burrs on the end faces or edges of stainless steel plates after stamping or mechanical processing, it not only affects the appearance of the product, but also affects the effectiveness of the machine. If mechanical polishing or manual deburring is used, it not only has low efficiency, but also cannot meet the requirements of rounded corners and chamfering in the design. Special chemical polishing or electrochemical polishing solutions are used to corrode the burrs without damaging the surface finish, and even improving the surface finish. This is a combination of surface treatment and mechanical processing.

(2) Remove excess dimensions. For a certain stainless steel spring steel wire, the wire diameter requirement is 0.8-0.84, but the actual wire diameter is 0.9. How to make the finished product uniform to 0.8-0.84? How to effectively remove burrs during machining and oxide films generated during heat treatment? If mechanical polishing and pliers repair are to be used to remove burrs, oxide scales, and evenly remove 0.06~0.1mm on the circumference of the steel wire diameter Not only is the processing technology poor and the efficiency low, but the processing quality is also difficult to guarantee. By using a special solution for chemical polishing, it is possible to simultaneously remove burrs, oxide scales, and uniformly remove excess wire diameter dimensions. For some sheet-like stainless steel parts with larger dimensions, special solutions for electrochemical polishing can be used to appropriately reduce the thickness and size to meet the product size requirements.

(3) Milling and cutting processing. Expose the parts of stainless steel material that need to be processed to chemical milling fluid for milling processing, in order to obtain parts of a certain shape or size, achieving the purpose of three-dimensional and decorative. By using screen printing, text, patterns, and designs can be chemically milled onto the surface of stainless steel to a certain depth, and then filled with different colors such as medals, signs, nameplates, etc.
