1. Technological process of ABS plastic plating
degreasing → water washing → roughening → water washing → colloidal palladium activation → water washing → gel release → water washing → chemical nickel plating → water washing → nickel electroplating → water washing →copper electroplating→ water washing→ chrome electroplating→ water washing→drying
2. Main process introduction
2.1 Degreasing:remove oil and reducing its surface tension, endowing it with surface hydrophilicity.
2.2 Roughening:improve surface roughness and increase surface area to increase the adhesion between metal coatings and plastics; Make the plastic surface change from hydrophobic to hydrophilic, and all parts are evenly wetted with water to evenly adsorb metal ions.
2.3 Colloidal palladium activation:a layer of easily oxidized material is adsorbed on the surface of the product, so that Redox can occur during the activation treatment, and a precious metal film with catalytic effect can be formed on the surface of the product.
2.4 Gel release:generate a layer of palladium metal film on the surface of the product.
2.5 Chemical nickel plating:plating a layer of nickel on the surface of the workpiece to strengthen the conductive layer.
2.6 Electroplating:plating the required coating on the surface of the product.
4.Common faults and solutions
|Common faults||Cause of occurrence||Solution|
|Pitted spot||Impurities in electroplating water||Using deionized water|
|Solid impurities in the electroplating bath||Strengthen filtering|
|Excessive coarsening||Adjusting the roughening process|
|Pinhole||Uneven air stirring in electroplating tank||Improve air stirring|
|Exposed plastic||Electroplating tank contaminated with roughening solution||Prevent coarsening solution from entering the plating bath|
|Insufficient thickness of chemical nickel plating||Adjust the nickel plating solution within the process range|
|Yellowing||Chromium layer too thin||Increase chromium plating current|
|Scorch||Excessive current in the local part of the product||Reduce current|
|Rust||Poor conductivity of hanging tools||Make a new hanging tool|
|Strong corrosive media present in the environment||improve environment|
|Bubbling||Poor material performance||Select electroplating grade ABS|
|Excessive or poor roughening||Reduce or increase the coarsening level appropriately|
