Analysis of Electrostatic Spray Painting Process for Four-Post Car Lifts
As a core equipment in the automotive repair industry, the surface treatment of four-post car lifts directly affects their durability and aesthetics. Electrostatic spray painting technology uses a high-voltage electric field to charge powder coatings, ensuring even adhesion to metal surfaces. Compared to traditional painting methods, this process offers stronger adhesion, more uniform coating, and no solvent emissions.
The process begins with pre-treatment steps such as degreasing and phosphating to ensure a clean substrate. Next, an electrostatic spray gun applies epoxy or polyester powder to the workpiece, which is then cured at 180-200°C to form a dense protective layer. The finished product exhibits excellent corrosion resistance, wear resistance, and color stability, making it ideal for harsh workshop environments with moisture and oil contamination.
Currently, this technology is widely used in high-end four-post car lift manufacturing, significantly extending product lifespan and reducing maintenance costs. It stands as the preferred solution for surface treatment in industrial equipment.
