Stainless steel etching processing need to pay attention to what

Stainless steel etching processing is a technology that uses chemical corrosion methods to etch the stainless steel surface with the desired pattern or text. The processing process requires attention to the following matters:

1. Drawing design: Before carrying out stainless steel etching processing, first design the required pattern or text. The design should consider the symmetry of the pattern, the thickness of the lines, spacing and other factors to ensure that the effect after etching meets the requirements.

2. Material selection: stainless steel etching should be selected from good quality stainless steel materials, such as 304, 316 and so on. These materials have good corrosion resistance, can ensure that the pattern or text after processing is not easy to be oxidized or discolored.

3. Screen production: according to the drawings designed pattern or text, the production of the corresponding screen. Screen can use photographic film or laser engraving and other methods of production, its accuracy and resolution will affect the final etching effect.

4. Etching solution preparation: stainless steel etching processing requires the use of specialized etching solution. The composition of etching solution mainly includes hydrochloric acid, nitric acid, hydrofluoric acid and so on. In the preparation of etching solution, pay attention to safe operation, avoid chemical splash or corrosion of the skin.

5. Etching treatment: place the made stencil on the surface of stainless steel, and then use a spray gun or brush to apply the etching solution evenly on the surface of stainless steel. In the etching process, pay attention to control the amount of etching solution and time, so as not to over-etching or under-etching.

6. Cleaning and drying: After completing the etching process, the etching solution on the stainless steel surface should be rinsed off with water in time, and then the surface should be dried with a dryer. This can avoid residues on the stainless steel surface caused by corrosion or pollution.

The main processes of stainless steel etching processing include:

1. Screen production: according to the drawings designed pattern or text, make the corresponding screen.

2. Material preparation: Selection of good quality stainless steel materials, and the necessary pre-treatment, such as cleaning, polishing, etc..

3. Etching solution preparation: according to the desired etching effect, prepare the appropriate proportion of etching solution.

4. Etching treatment: place the made stencil on the surface of stainless steel, and then apply the etching solution evenly on the surface of stainless steel with a spray gun or brush. Control the amount of etching solution and time to get the desired etching effect.

5. Cleaning and drying: After completing the etching process, rinse the etching solution on the stainless steel surface with water in time, and then dry the surface with a dryer.

6. Quality check: the processed stainless steel surface quality check to ensure that the pattern or text in line with the design requirements, and no residue or damage to the surface.

7. Packaging and transportation: the processed stainless steel products are packaged and transported to avoid damage or contamination during transportation.

In short, stainless steel etching processing is a technically demanding process that requires strict control of the quality and safety of all aspects of the operation. In the actual stainless steel etching processing manufacturer in the etching process, it is also necessary to adjust and optimize according to the specific circumstances in order to obtain the best processing results.
