Why automotive glass is challenging—and how we solve it

Automotive glass must meet demanding optical and safety requirements while integrating various functional components.

Challenges

  • Transparency & glare: highly polished surfaces make scratches and sleeks easy to miss
  • Curvature & thickness: bending and laminating introduce refraction and double images
  • Functional layers: ceramic frit, coatings, HUD zones, conductive heaters, encapsulation
  • Edge quality: long perimeters with holes/slots increase risk of chips and micro-cracks

Intelgic Solutions

  • Lighting matched to panel and task to reveal defects without glare
  • Custom machine vision design tuned for each glass model and curvature
  • Live Vision AI trained on automotive datasets to separate true defects
  • Microscopic capability detects ≈10–20 µm scratches and edge chips ≥20 µm

Intelgic Approach

Our turnkey solution combines precision optics, application-specific lighting geometry, multi-axis motion, and Live Vision AI.

Advanced Lighting

Low-angle oblique + controlled dark-field reveals hairline scratches without glare. Telecentric backlight creates crisp silhouettes for edge inspection.

Live Vision AI

Trained on automotive datasets to separate true defects from heater lines, prints, and structured reflections with high accuracy.

Digital Quality Certificate

Tamper-evident digital record for every PASS panel with defect snapshots, measurement summaries, and full traceability.

What We Inspect

Comprehensive defect detection across all critical areas of automotive glass.

Surface & Cosmetic

Hairline scratches, sleeks, scuffs, digs/pits, stains, water spots, haze and rainbow artifacts on coated zones.

Frit & Printing

Ceramic frit pinholes, voids, smears, edge raggedness. Logo/mark presence, contrast, size, and position.

Edges & Cutouts

Perimeter chips, micro-cracks, shelling; bevel/chamfer quality. Hole/slot presence and size; VIN viewport sizing.

Functional Features

ADAS camera & sensor brackets position/orientation. Backlite defogger lines continuity. Encapsulation quality.

Geometry & Optical

Outer contour vs. CAD overlay. Curvature/sag checks. Optional deflectometry for distortion/slope mapping in HUD region.

Traceability

OCR/OCV of part numbers, E-marks, date/shift codes; barcode/2D code verification for complete traceability.

System Architecture

Precision-engineered components working in harmony for reliable inspection.

Frequently Asked Questions

Yes. AI models are trained on heater line patterns and use frequency/shape cues to avoid false positives; low‑angle dark‑field highlights true micro‑scratches.

Yes. We measure bracket pose vs. datums and check bead presence, width, and squeeze‑out. Orientation errors and missing/extra components are flagged.

Optionally, a deflectometry module maps slope/distortion and wedge proxies in the driver eye‑box and HUD region for process tuning and acceptance decisions.

With multi‑axis rails/gantry and soft‑nest or vacuum fixtures that stabilize the part while keeping optical surfaces safe.

Per‑panel DQC, shift/day reports, defect Pareto, and full audit logs with user actions; secure sharing for OEM/Tier‑1 stakeholders.
