Turnkey Solution

Precision Inspection for Complex Plastic Parts

Combining advanced imaging, tailored lighting, and Live Vision AI to detect defects at production line speeds.

Precision Imaging

High-resolution cameras with application-specific optics capture every detail, from micro-scratches to dimensional variations.

Tailored Lighting

Custom lighting geometry for each surface type—dome for glossy, dark-field for textures, polarized for chrome/PVD.

Live Vision AI

Reflection-aware AI trained specifically on automotive plastics reduces false positives from specular highlights and texture grains.

2D + 3D Fusion

Combines high-resolution 2D imaging with structured-light 3D metrology for comprehensive dimensional verification.

Multi-Axis Motion

Rotary/tilt tables and robotic rails eliminate blind spots on complex geometries with deep ribs and undercuts.

Digital Quality Certificates

Each inspected part receives a traceable DQC with annotated defect snapshots and measurement values.

Why Plastic Automotive Parts Are Hard to Inspect

Plastic components present unique inspection challenges that traditional vision systems struggle with:

  • Complex geometry with deep ribs, clips, bosses, and undercuts create shadows and occlusions
  • Diverse finishes from high-gloss paint to textured matte each require different optics
  • Specular glare on glossy/plated surfaces hides micro-defects while low albedo black plastics reduce contrast
  • Color/texture variation across lots and warpage that distorts geometry
  • Mixed assemblies with inserts, gaskets, and lightguides requiring multi-modal checks

The Intelgic Approach

Our turnkey solution is specifically engineered to overcome these challenges:

  • Lighting matched to surface & shape: dome/coaxial for glossy, dark-field for sleeks, polarized for chrome
  • Multi-camera, multi-angle coverage with robotic motion to eliminate blind spots
  • 2D + 3D fusion combining appearance inspection with dimensional verification
  • Reflection-aware AI trained on automotive plastics to reduce false positives
  • Custom machine vision design per part based on your CAD and tolerances
