Abstract: This paper studies the electrophoretic shrinkage of the window frame, analyzes the causes of the shrinkage from the structure and process of the window frame, and verifies that the anti rust oil in the crack of the window frame is the direct cause of the shrinkage. By optimizing the rolling crack, compressed air to clean up the liquid in the gap, and replacing the better compatible antirust oil, the poor shrinkage can be controlled. Finally, the innovative scheme of introducing water-based antirust agent can solve the problem of electrophoretic shrinkage of window frame.
