Metal surface treatment - ED(electrophoresis Deposition)


Electrophoresis: the movement of a charged particle toward its typically opposite electrode under the action of an electric field, called electrophoresis. Used for stainless steel, aluminum alloy, etc., can make the products present various colors, and maintain the metal luster, and enhance the surface performance, with better anti-corrosion performance.
Pros: colorful
Mature technology, mass production
The surface treatment of complex structure can be realized by processing in liquid environment
No metal texture, can cooperate with sandblasting, polishing, drawing etc

Disadvantages: the ability to cover defects is general, and the preprocessing of die castings by electrophoresis is required to be higher
Process cost: continuous operation of mechanization and automation, low labor cost, low total cost
Production speed: faster production speed
Process: pretreatment - electrophoresis - drying
