In modern coating processes, surface pretreatment is regarded as the "key first step" that determines coating
adhesion and final quality. Ultrasonic cleaning technology, known
for its efficiency, precision, and eco-friendliness, is widely
applied in the degreasing phase of both electrophoretic and powder
coating lines, making it an essential high-end cleaning solution
for the coating industry.
Application in Electrophoretic Coating Lines
In electrophoretic coating, parts must undergo strict pretreatment
processes including degreasing, rinsing, and phosphating. Residual oil, particles, or rust can lead to coating defects like
cratering, peeling, or pinholes. Traditional spray or immersion methods struggle to clean complex
structures such as welded joints, blind holes, and inner cavities
of metal parts.
Ultrasonic cleaning uses high-frequency vibrations (tens of
thousands of times per second) to create and collapse microscopic
bubbles in the cleaning liquid. This cavitation effect effectively penetrates gaps and blind areas, removing emulsified
oils and contaminants, significantly improving the adhesion and uniformity of the
coating, and reducing rework rates.
Advantages in Powder Coating Lines
While powder coating involves no solvents in the finishing stage, surface cleanliness still determines the adhesion, uniformity, and
long-term corrosion resistance of the coating. Powder coating is widely used for steel, aluminum, furniture,
doors, railings, and other products, with large production volumes
and high consistency demands.
Ultrasonic cleaning dramatically improves degreasing efficiency,
helping to prevent bubbling, cracking, or powder peeling. It is ideal for thick coatings and decorative finishes requiring
high performance and visual quality. Its automation and
eco-friendly operation make it a favored solution in modern powder
coating lines.
