AI For Quality

Catch Every Defect, Before It Leaves The Line.

Industrial-grade computer vision deployed at the inspection station - detecting defects, verifying parts, reading codes, and classifying products with millisecond latency and consistency no human operator can match across an eight-hour shift.

The Shift

Human Inspection Is Honest. It Is Not Consistent.

Trained operators are skilled, but they blink, they tire, and they vary between shifts. Vision AI brings the same trained eye to every part on every line, every hour of every day - with full image evidence behind every reject.

Without AI for Quality

  • Defect rates drift between A-shift, B-shift, and weekend operators
  • No image record of why a part was rejected - just an operator's mark
  • Customer warranty claims surface defects that escaped end-of-line inspection
  • Adding inspection capacity means hiring and training new operators
  • Inspection station bottlenecks line speed during high-mix production

With Nexren AI

  • Identical inspection criteria applied 24/7, with no variance between shifts
  • Every accept and reject decision logged with the original image and confidence score
  • Defect escape rate cut by 80–95% - measured against your historic baseline
  • Inspection scales by adding cameras, not headcount
  • Real-time inference at full line speed, integrated directly with your PLC
Core Capabilities

Four Inspection Capabilities. One Unified Vision Platform.

Each capability runs on the same Nexren vision core - meaning a single deployment covers your entire quality station, with consistent logging, audit trails, and traceability into your MES.

Visual Defect Inspection

Deep-learning vision models trained to detect scratches, dents, cracks, weld defects, surface contamination, dimensional deviation, and assembly errors - at line speeds traditional rule-based systems can't sustain.

  • YOLOv8-class architectures fine-tuned per part family
  • Anomaly detection for unseen-defect coverage
  • GigE / USB3 / line-scan camera compatibility
  • Configurable accept / reject / review tiers

OCR & Barcode Verification

Read printed lot codes, serial numbers, DOT marks, 1D / 2D barcodes, and DataMatrix at production speed - automatically cross-checking against MES expected values to catch mis-labelling before despatch.

  • Deep-learning OCR robust to glare, embossing, low contrast
  • 1D / 2D / DataMatrix / DPM code decoding
  • Real-time mismatch alerts to operator HMI
  • Full audit log for traceability compliance

Child-Part Presence Check

Confirm every required child component, fastener, clip, washer, gasket, or sub-assembly is present and correctly seated - eliminating the most common warranty failure: a missing or misoriented part shipped at scale.

  • Multi-region inspection in a single frame
  • Orientation & seating verification
  • Colour / variant differentiation for similar SKUs
  • PLC handshake for automatic reject diverter

Product Classification

Automatically sort, route, or grade products based on visual attributes - variant, size, colour, quality grade - replacing manual sorting stations and reducing classification errors in mixed-model production.

  • Fine-grained classification across hundreds of SKUs
  • Quality-grading (A / B / scrap) by surface attributes
  • Direct integration with sortation conveyors
  • Self-learning loop on operator overrides
Where It's Deployed

Trusted on Lines That Can't Afford a Wrong Call

From powertrain components to packaged goods, Nexren's vision AI is deployed wherever a single missed defect translates directly into a warranty claim, recall, or line stoppage.

01

Automotive Powertrain - Nut & Fastener Presence

Critical-fastener inspection on engine and transmission assemblies - verifying torque-witness marks and child-part presence at end-of-line, with PLC-triggered reject for any failed unit.

0 PPMEscapes (typical)
18msInference time
02

Electronics & PCB - Surface & Solder Inspection

Component placement, solder joint quality, and surface contamination detection on populated PCBs - replacing slow manual AOI review with real-time machine vision at 3× the throughput.

99.7%Detection accuracy
Throughput vs AOI
03

Packaging & FMCG - Label, Code & Seal Verification

Label correctness, lot-code legibility, fill-level, and seal integrity inspection on high-speed packaging lines - catching mis-prints and seal failures before pallets are wrapped.

How It Works

From Camera Trigger To Verdict In Milliseconds

A deployment process designed for industrial environments - ruggedized, deterministic, and built to fit alongside existing PLCs, HMIs, and MES systems.

1

Capture

Industrial camera (Hikvision, Basler, Cognex) triggered by PLC sensor - image transferred over GigE to the edge inference unit in real time, with no line stoppage required.

2

Infer

Model runs on edge GPU (NVIDIA Jetson / RTX) with deterministic sub-25ms latency - verdict returned to the PLC before the part reaches the reject diverter.

3

Act

PLC diverts rejects, lights stack-lights, and triggers operator alerts - every event logged with image evidence and confidence score.

4

Learn

Operator overrides and false-positive feedback continuously retrain the model - accuracy compounds week over week without manual relabelling.
