Electroplated workpieces need to be leveled to ensure a uniform thickness of the plating layer. Unevenness in the surface of the workpiece can cause uneven deposition of the plating material, resulting in a non-uniform thickness of the plating layer.
This can lead to problems such as poor adhesion, corrosion, and uneven appearance. Leveling the workpiece before electroplating ensures that the plating material is deposited evenly across the entire surface of the workpiece, resulting in a uniform and high-quality plating finish.
