Electrophoresis technology for doors and windows is a surface treatment process mainly used for corrosion prevention and decoration of metal doors and windows. The following are the core points of the technology:
- Basic principle
Electrophoretic coating utilizes the action of electric field to make the charged paint particles move directionally in the solution and deposit on the metal surface to form a uniform coating.
- Main steps
Pre-treatment: Clean the metal surface and remove oil and oxides.
Coating elektrôziana: Immerse doors and windows into the electrophoretic tank and deposit the paint particles on the surface after energized.
Water washing: Remove unadhered paint.
Drying and curing: Curing the coating by heating.

Mitovy: Uniform coating thickness and good coverage.
Corrosion resistance: Provides excellent corrosion resistance.
Environmental friendliness: High utilization rate of the coating and low pollution.
Decorative: A wide range of colors can be blended to enhance aesthetics.

Widely used in aluminum alloy, steel doors and windows, applicable to construction, household and industrial fields.
- Precautions
Pre-treatment: surface cleanliness affects coating quality.
Process control: Zintin'aratra, time and other parameters need to be precisely controlled.
Equipment maintenance: regular maintenance of electrophoresis tank and electrode.

Doors and windows electrophoresis technology realizes the anti-corrosion and decoration of metal doors and windows through electrophoresis coating, which has the advantages of uniformity, anti-corrosion, environmental protection and aesthetics, and is widely used in many fields.
Electrophoresis technology and powder spraying technology are both common surface treatment processes, but they have significant differences in working principle, coating performance and scope of application. The following are the main advantages of electrophoresis technology over powder coating technology:
- Coating uniformity
Electrophoresis technology: Through the action of electric field, the coating particles are uniformly deposited on the surface of the workpiece, even complex shapes or internal cavities can be well covered with consistent coating thickness.
Powder spraying technology: relying on electrostatic adsorption, complex shapes or corners may not be covered evenly, and the problem of inconsistent coating thickness is likely to occur.
- Corrosion resistance
Electrophoresis technology: the coating is closely combined with the metal substrate, with excellent anti-corrosion performance, especially suitable for outdoor or highly corrosive environments.
Powder coating technology: better anti-corrosion performance, but not as dense as electrophoretic coating, long-term exposure to harsh environments may be slightly inferior.
- Environmental friendliness
Electrophoresis technology: high utilization rate of coating (close to 95%), less waste, low solvent content, less pollution.
Technology coating Powder: Although the powder can be recycled, there is still powder waste in the spraying process and the recycling system is complicated.
- Complex workpiece treatment
Electrophoresis technology: It is suitable for dealing with workpieces with complicated shapes, internal cavities or gaps, and the coating can cover evenly.
Powder spraying technology: limited ability to cover complex workpieces, prone to dead corners or thin coatings.
- Coating adhesion
Electrophoresis technology: strong adhesion between the coating and the substrate, not easy to come off.
Powder spraying technology: better adhesion, but may cause cracks or peeling when mechanically impacted or bent.
- Production efficiency
Electrophoresis technology: suitable for continuous production of large batch and high automation.
Powder spraying technology: suitable for small batch or customized production, but relatively low efficiency.
- Appearance quality
Electrophoresis technology: smooth and delicate coating surface, suitable for high decorative requirements.
Powder spraying technology: the coating is thicker, may appear orange peel or granularity, the appearance is not as delicate as electrophoretic coating.
- Cost
Electrophoresis technology: Higher initial equipment investment, but high coating utilization rate and lower long-term cost.
Powder spraying technology: lower equipment investment, but more powder waste, long-term cost may be higher.

Electrophoresis technology is better than powder spraying technology in terms of coating uniformity, anticorrosion performance, environmental protection, complex workpiece processing, sns. It is suitable for high requirements and mass production. Powder coating technology is more suitable for small batch and low cost application scenarios. The choice of technology needs to be based on specific needs and workpiece characteristics to decide.
