Plastic electroplating can give the surface of plastic products a metallic luster, aesthetic appearance, and decorative effect; Improve the mechanical strength of the product surface and extend its service life; Make plastic products more stable to external factors such as light and atmosphere, and less prone to aging; Plastic electroplated products can be used in industries such as aerospace, shipbuilding, automotive labeling, electronic appliances, building decoration, toys, and daily necessities. They have a wide range of applications, with the largest usage, the most mature technology, and the best electroplating effect.

The main process flow of ABS electroplating logo is as follows: degreasing, roughening, sensitization, activation, chemical plating, electroplating, nickel plating, chromium plating, and finished product. The five steps before the electroplating operation in the above operation are chemical plating process, and the conventional electroplating process starts from the electroplating operation.

Oil removal: The main purpose of oil removal is to degrease and remove oil, while reducing its surface tension and endowing it with hydrophilicity. During the processing or transportation of the parts, it is inevitable that they may come into contact with oil stains, release agents, and some impurities, which affect subsequent operations. These factors must be removed through degreasing operations.

Coarsening: The purpose of roughening is to improve surface roughness, increase surface area, and enhance the adhesion between metal coatings and plastics; Change the surface of plastic from hydrophobic to hydrophilic, and evenly wet all parts with water to facilitate the uniform adsorption of metal ions.

Sensitization: The purpose of sensitization is to adsorb a layer of easily oxidizable substance on the surface of the workpiece, so that oxidation-reduction reactions can occur during activation treatment, and a catalytic precious metal thin film can be formed on the surface of the workpiece.

Activation: The purpose of activation is to form a metal film on the surface of the workpiece (adsorbing catalytic substances such as gold and copper onto the sensitive surface of the workpiece), which serves as a catalyst for the next step of chemical deposition and facilitates chemical plating.

Chemical plating: After activation treatment, the surface of the workpiece already has a layer of silver or other metal film, but due to its thinness, if immersed in an acidic solution, the silver film will peel off. Therefore, alkaline chemical copper plating is required first. Through redox reaction, a layer of copper is plated on the surface of the workpiece to strengthen the conductive layer. Then, electroplating can be carried out in an acidic medium.
