Difference between electrophoresis lattice frame and oil spraying of brand tag-A

“Brand tag electrophoresis lattice frame” and ‘oil spraying’ are two different surface treatment processes, there are significant differences in the process principle, application effects, scope of application and so on.

First. difference in process principle
Electrophoresis Racking
Principle: Based on electrophoresis technology, the electrically charged lattice particles (usually resin-like substances) are deposited on the surface of the workpiece to form a uniform coating through the action of electric field.
Process: The workpiece is immersed into the electrophoresis solution as an electrode, and the electrically charged particles move directionally and attach to the surface after energization, forming a protective layer after curing.
Oil Spraying
Principle: Using compressed air or mechanical pressure to atomize the paint and spray it on the surface of the workpiece to form a continuous coating.
Process: Spray paint in the form of tiny particles through the spray gun, relying on solvent volatilization or chemical reaction curing.
Second.comparison of application effect
Coating quality
Electrophoretic lattice: The coating is uniform and dense, with controllable thickness (usually 10-30μm) and excellent edge coverage, suitable for complex shaped workpieces.
Oil spraying: the coating thickness is affected by spraying parameters (15-50μm), easy to flow hanging, orange peel and other defects, the effect of flat workpiece is better.
Performance
Electrophoretic lattice: strong corrosion resistance (salt spray test can reach more than 500 hours), high hardness (2H-4H), excellent weather resistance.
Oil spraying: weaker corrosion resistance (salt spray test 50-200 hours), lower hardness (HB-2H), need additional varnish to enhance protection.
Environmentally friendly
Electrophoretic lattice: water-based system, low VOC emission (<50g/L), in line with environmental regulations. Oil spraying: solvent-based paint with high VOC emission (>200g/L), requires supporting exhaust gas treatment equipment.

Third.differences in scope of application
Electrophoretic lattice frame
Typical applications: automobile parts (wheel hubs, chassis), household appliance shells, hardware products, etc.
Advantageous areas: need high corrosion resistance, batch processing of complex structural parts.
Oil spraying
Typical applications: wood furniture, plastic products, toys, handicrafts, etc.
Advantageous areas: flat or simple curved surface workpieces with high requirements for decorative properties.
