Paint & Coating Inspection


Different Colors. Metallic or Mate. Reliably Identifies All Common Defects.

Inspections of painted, wet, or powder-coated materials are critical to guaranteeing the final product's quality, appearance, and performance. Product inspection is complex due to coating concealing defects, variations in coating quality, and the need for specialized inspection methods. Environmental factors can also impact results, making precision and adaptability crucial.


Visual Inspection

This is the most common method for inspecting painted materials. SANZEZOO UNITY visually examines the surface for defects like scratches, bubbles, uneven covarage, streaks, runs, or perfections.


Surface Contamination

SANEZOO UNITY looks for contaminats on the surface , such as dust , dirt, or other foreign particles, which can affect the quality of the coating.


Surface defect detection

SANEZOO UNITY can indentify common defects such as orange peel, blistering, sagging , or dry spray. The system uses advanced imaging technology and algorithms to detect defects that may be hard to spot with the human eye.

Coated Product Defect Detection: Possibilities and Process


Raised, bubble-like deformities on the coating surface caused by trapped air or moisture.

Color Variations

Inconsisttent or uneven color across the coated surface.

Cracking or Flaking

Fine or coarse cracks or paint layers peeling away from the substrate.

Orange peel

Surface texture resembling the texture of an orange peel, caused by improper paint application.

Sagging or dripping

Runs, sags, or drips in the paint due to excessive application.

Fish Eyes

Small craters or circular imperfections in the coating caused by contaminants.

Detecting defects on differently colored painted parts involves capturing multiple layers of photos to mitigate color variations. This method enhances defect detection precision, ensuring that imperfections like scratches, cracks, or irregularities are reliably identified, even on parts with varying paint colors.

Varying textures can create irregular reflections and shadowing, further complicating defect identification. By capturing different layers of images, these complexities are addressed, enhancing defect detection of blisters or surface irregularities.

This approach enhances the precision of defect detection, ensuring that the texture, as well as color, is carefully considered for a more reliable assessment of painted parts.
