Technical Field

Background

In order to ensure the service life of steel parts, the steel parts are generally required to be coated after being produced, the conventional coating comprises electrophoresis, powder spraying and the like, and the electrophoresis has the advantages of uniform coating, high speed and safety.

The parts needing electrophoresis are generally produced, electrophoresed and dried according to the designed shape and requirements, the parts with the conventional appearance are dried simply, but for a spacing multilayer structure or a tubular structure, such as a breast board of a pick-up truck, the parts are usually of a multilayer plate structure, and due to the semi-closed state of the interior of the parts, when electrophoresis is carried out through a conventional electrophoresis rack, the electrophoresis paint liquid cannot completely fill the interior space, namely, air is reserved in the interior. If the gas is not vented, the parts in contact with the air will not be electrophoretically coated.

Therefore, in order to ensure the coating of the parts, the through holes are usually reserved during the design, so that when the parts invade the electrophoretic paint liquid, the gas can be naturally discharged, but the mode puts higher requirements on the structural design and increases the difficulty of manufacturing; another way is to manually intervene on each part during electrophoresis, which is similar to glazing the inside and outside of a ceramic bottle, and this will result in a great reduction in the efficiency of electrophoresis.
