Challenge
When Microscopic Surface Defects Lead to Multi-Million-Dollar Risks
In high-throughput manufacturing, fractions of a millimeter determine whether a part is prime quality or costly scrap. Yet in day-to-day operations, quality and production managers face the same critical bottlenecks:
Manual Visual Inspection Reaches Its Limits
Human operators suffer fatigue after short periods. The inevitable outcome: fluctuating inspection accuracy, overlooked batch defects, and unsustainable labor costs.
Costly Recalls & Reputational Damage
If a flawed component reaches final assembly or the end customer (e.g., in automotive tier-1 or medical technology), manufacturers face expensive recalls, contractual penalties, and permanent brand damage.
High False Reject Rates (Pseudo-Scrap)
Outdated optical systems often reject good parts because they cannot differentiate between harmless reflections, dust, or oil film and true functional defects. This drives material costs through the roof.
The aku.automation Standard
Quality must never be left to chance. Our automated surface inspection systems deliver 24/7 objective, reproducible, and 100% inline defect detection – directly integrated into your production line.
Your Solution – What aku Surface Inspection Delivers
High-Precision Defect Detection in Real Time – Your Commercial Advantages
Our turnkey systems capture and evaluate surface features using maximum optical resolution and bespoke inspection algorithms. You achieve absolute process reliability and maximum yield:
100% Inline Inspection in the Micron Range
Say goodbye to statistical random sampling. Every single workpiece is inspected fully automatically and without gaps – even at maximum production line speeds.
Minimizing False Rejects with AI
Leveraging intelligent filtering and deep learning algorithms, our systems reliably distinguish between critical functional defects and harmless cosmetic variations (such as fingerprints or light lubricants).
Complete Traceability & Audit Compliance
Every inspection result, high-resolution defect image, and statistical parameter is digitally logged and archived. Meet ISO and IATF requirements effortlessly and maintain bulletproof evidence in case of warranty claims.
Seamless Line Integration
Whether as a retrofit into brownfield lines or integrated into new greenfield machinery: Our systems interface smoothly with your PLC and line controls via industrial standards (OPC UA, Profinet, Ethernet/IP, etc.).
Inspection Spectrum: Which defects do our systems detect?
Comprehensive Defect Classification Across Diverse Materials
Whether metallic, polymer-based, painted, or transparent – our machine vision solutions reliably expose even low-contrast or topographical defects:

Mechanical Damage Detection
- Scratches & score marks (including microscopic hairline cracks)
- Impact marks & chipping
- Burrs & flash along punched or cut edges

Topographical Defect Detection
- Dents & dings on complex freeform surfaces
- Pores, blowholes & voids (e.g., in castings and welds)
- Waviness & warpage

Coating & Color Flaws Detection
- Color deviations & surface inhomogeneities
- Blisters, orange peel & paint runs
- Coating voids in anodized, plated, or PVD layers
Applied Technologies: Tailored High-End Machine Vision
The Right Vision Technology for Every Surface Characteristic
No two surfaces are alike. aku.automation combines premium optical sensors with proprietary algorithmic processing for optimal detection rates:

Deflectometry (Phase-Measuring Deflectometry)
The gold standard for specular, mirror-like, and high-gloss 3D surfaces. By projecting periodic fringe patterns, our systems reveal nanometer-scale distortions and dents that remain invisible to conventional vision setups.

Shape from Shading (Photometric Stereo)
Separates surface texture from 3D height data. Ideal for matte to semi-gloss components, delivering high-contrast rendering of flat defects (such as fine scratches or stamped defects) regardless of distracting background patterns.

AI & Deep Learning Vision
Where rule-based image processing fails due to natural material variations, our neural networks evaluate surfaces like an expert human inspector – classifying complex defect classes and virtually eliminating false rejects.
