QUALITY CONTROL VALUE

From Visual Evaluation to Repeatable Quality Control

Manual zebra-angle assessment can vary with operator judgement, viewing position and inspection conditions. FZT-2 provides a defined automated measurement workflow to produce quantitative, repeatable results for glass quality evaluation.

  1. 01

    Reduce Operator Dependency

    Replace subjective visual judgement with a consistent automated measurement process.

  2. 02

    Improve Measurement Consistency

    Evaluate samples and production batches using the same defined measurement method.

  3. 03

    Generate Traceable QC Records

    Automatically record measurement results and create structured reports for later review.

  4. 04

    Support Quality Investigation

    Retrieve previous measurements when investigating production variation, customer concerns or process changes.

System Architecture

An integrated measurement system composed of optical, mechanical, and software modules, working in coordination to ensure high stability, accuracy, and repeatability throughout the measurement process.

Analysis Software

Processes the captured image, identifies stripe deformation and automatically calculates the quantitative zebra-angle result.

FZT-2 mechanical positioning system
04

Mechanical Positioning

Controls sample positioning and measurement geometry to support consistent, repeatable testing.

Installation Evidence

System Integration

Automatic Reporting

Every Measurement Becomes a Searchable Test Record

The FZT-2 automatically generates a test report after each measurement. Reports are stored locally on the industrial PC and named using the exact test date and time.

  • Quantitative zebra angle result
  • Sample data, deformation curves and tendon-position outputs
  • Time-based file naming for historical traceability
  • Storage for up to two years, depending on configured capacity
