company news about Electroplating

Electroplating is a commonly used metal surface treatment process. The specific process typically includes the following steps:

1. Pre-treatment:

   • Cleaning: Use chemical cleaners to remove oil, dust, and rust from the surface. Common cleaning methods include ultrasonic cleaning and acid cleaning.
   • Water Rinsing: Rinse with water to remove any residues of the cleaning agent.

2. Activation:

   • Perform activation treatment on the metal surface to enhance its bonding with the plating layer. This can be done using acid cleaning or chemical activators.

3. Electroplating:

   • Preparation of Electroplating Bath: Prepare the electroplating solution, which usually contains metal salts, additives, and pH regulators.
   • Hanging the Workpiece: Connect the workpiece to the cathode of the power supply; the anode is typically the metal to be deposited (such as nickel or copper).
   • Electroplating Process: Under the influence of electric current, metal ions are reduced from the electroplating solution and deposit onto the surface of the workpiece, forming a plating layer. The plating time and current density should be adjusted according to the material of the workpiece and the requirements for the plating layer.

4. Post-treatment:

   • Water Rinsing: After electroplating is complete, immediately rinse the workpiece with water to remove any residual electroplating solution.
   • Drying: Use hot air or allow the workpiece to air dry.
   • Passivation: In some cases, a passivation treatment is performed to enhance the corrosion resistance of the plating layer.

5. Quality Inspection:

   • Inspect the plating layer for thickness, adhesion, appearance, etc., to ensure it meets the required specifications.

This is the basic process of electroplating, and specific parameters and steps may vary based on different metal materials and application requirements.
