The manufacturing of electroplated cosmetic shells involves multiple delicate steps aimed at creating products that are both aesthetically pleasing and durable. The following is a typical electroplating process that outlines the main stages from raw materials to finished products:

1. Raw material preparation
-* * Material selection * *: Select suitable substrate materials according to design requirements, such as metal, plastic, or other electroplated synthetic materials.
-Dimensional processing: Using methods such as stamping, injection molding, CNC milling, etc. to shape and dimension materials into the desired shape and size.

2. Surface pre-treatment
-Degreasing and degreasing: Use chemical solutions to remove surface oil, dust, and other impurities to ensure adhesion in subsequent processes.
-Polishing and Grinding: Mechanical removal of burrs to increase surface smoothness and lay the foundation for electroplating.
-Acid washing (if applicable): Treatment with weak acid solution to remove surface oxides and improve cleanliness.
-Passivation treatment (if necessary): Form a protective film to prevent corrosion during subsequent processing.

3. Preparation before electroplating
-Activation treatment: Sometimes chemical immersion is required to activate the surface of the substrate, making it easier to receive the plating layer.
-Pre plating: Apply a thin layer of bottom coating before formal plating to improve conductivity and adhesion.

4. Formal electroplating
-Electrodeposition: Using the workpiece as the cathode, metal ions are dissolved from the anode in the electrolyte and deposited on the surface of the workpiece under the action of an electric field.
-Temperature and current density control: Accurately adjust parameters to ensure uniform and dense coating.

5. Post processing
-Cleaning: Remove residual electrolyte to avoid corrosion.
-* * Closed treatment * * (optional): Add additional protective layer, such as varnish, to increase wear resistance and corrosion resistance.
-Inspection: Optical or physical testing to verify whether the coating quality meets the standards.

6. Assembly and packaging
-Assembly: Assemble the electroplated components into a complete product.
-* * Packaging * *: Properly packaged to prevent scratches and contamination during transportation.

Each step requires strict quality monitoring to ensure that every step meets high standards, thereby producing high-quality electroplated cosmetic shells. The details of the process flow may vary depending on the type of material, the electroplating technology used, and the final requirements.
