Automated Multi-layer Coating measurements systems with Terahertz Technology

The Challenge: Outdated Manual Inspection Methods

Multi-layer coating thickness measurement

In today’s fast-paced automotive industry, maintaining paint quality is essential for both aesthetics and durability. However, many paint shops still rely on manual, slow, and error-prone inspection methods, which: 

  • Are incompatible with modern automation systems 
  • Cannot accurately measure multiple paint layers 
  • Cause 1–5% vehicle rejections due to inconsistent coating quality 

This leads to costly reworks, wasted materials, and a negative impact on production efficiency and sustainability. 

Our Solution: THz-Based Coating Inspection System

At Teralumen Solutions, we’re transforming coating measurement with our advanced Terahertz-Time Domain system. A powerful Terahertz Non-Destructive Testing (NDT) device designed to measure precisely.  

Key Features of Our THz System: 

  • Multi-Layer Thickness 

In a single scan, all layer’s thicknesses can be measured automatically. 

  • Micron-Level Precision 
    Accurately measures individual layers: primer, basecoat, and clear coat—even on curved surfaces. 
  • Real-Time Measurement 
    Seamlessly integrates with robotic arms and production lines for continuous, contactless inspection. 
  • Defect & Delamination Detection 
    Identifies hidden defects such as poor adhesion or air pockets that traditional methods can’t detect. 

How It Works

  • THz Waves Penetrate Paint Layers:
    THz pulses are transmitted through all paint layers without damaging the surface. 
  • Reflections Are Captured & Analyzed:
    Each layer’s boundary generates a reflection due to change in polymer density, enabling precise thickness and defect analysis. 
  • Instant Display of Results:
    The Time-of-Flight of Terahertz waves are converted into thickness values and are shown in real time — allowing immediate feedback and action. 

Unlike traditional destructive tests, THz technology enables non-contact, inline analysis — without halting production — making it ideal for modern, automated paint shops. 

Key Benefits

By implementing terahertz technology, manufacturers can achieve up to 15% cost savings and reduce energy consumption per car. It helps to minimize defects and manual errors through inline robotic integration and operates with a user-friendly interface.
