On March 29th, the "2025 Forum on Focusing on Artificial Intelligence, Developing New Quality Productivity, and Promoting High Quality Development of the Surface Engineering Industry" hosted by the China Machinery Industry Enterprise Management Association and organized by China University of Metrology was successfully held in Hangzhou. As a technical expert in the field of intelligent detection and coating control, Industrial Physics attended the conference and delivered a keynote speech.
This conference conducted in-depth discussions on hot topics such as intelligent manufacturing, AI driven, and green development, attracting numerous experts and scholars from research institutes, universities, and manufacturing enterprises mainly focused on automobiles.
On the forum, Yang Sen, an industrial physics sales engineerEnhanced optical interference (ROI) assists intelligent surface detection, precise measurement drives automated coating controlTitle: In depth analysis of how ROI technology empowers intelligent manufacturing, triggering a warm response on site.
Accurate Coating MeasurementThe moment of qualitative change
67% of product failure accidents are caused by inadequate coating thickness. - Analysis of over 100000 cases from professional testing institutions in South China
From automotive electrophoretic coatings and photovoltaic conductive films to home appliance spraying and building steel structures, coatings as thin as cicada wings often affect performance, lifespan, cost, and safety. However, traditional measurement methods such as micrometers, microscopes, and lasers have drawbacks such as slow measurement, susceptibility to damage, poor repeatability, and scattered data, making it difficult to meet the industrial demand for "high precision+efficiency".
Yang Sen pointed out in the report that:The SpecMetrix film thickness analysis system is changing this situation through enhanced optical interference (ROI) technology.
For example, in the case of a European user usingSpecMetrix film thickness analyzerAfterwards, a comparison of the measurement results was made with two well-known thickness gauges. The distribution of multiple measurement results obtained by the original two thickness gauges is relatively scattered and has a large distribution range, while the data obtained by the SpecMetrix film thickness analyzer can be very dense and fall within a narrow range.
This also confirmed the accuracy, repeatability and progressiveness of the SpecMetrix film thickness analyzer.
What is ROI?Why can it be used for film thickness measurementRevolutionary?
ROI， Enhanced Optical Interference Method
SpecMetrix uses advanced multi wavelength interferometry and fast Fourier transform algorithms to achieve high-precision film thickness measurement without contact or damage.
Multi wavelength interferometry, multi wavelength synthesis, expanding measurement range
The software interface displays the real-time calculation process from interferograms to thickness values
✨ Characteristics of ROI enhanced optical interferometry:
•High measurement accuracy:± 3%, and written into ASTM D8331 standard
•Fast measurement speed:150 times/second, suitable for high-speed production lines
•Wide coverage:Transparent layer 0.75-350 μ m, coloring layer 0.75-75 μ m
•Compatible with AI production lines:Can be integrated with multiple PLCs to achieve measurement feedback regulation closed-loop
Especially suitable for measuring "difficult to chew bones" such as UV insulation coatings, porous ceramic coatings, sulfate coatings, etc., it is a true non-contact, non-destructive, sub micron level film thickness detection solution.
Global case sharing:Real benefits
At this forum, Yang Sen also shared several typical application cases:
🔹 Steel industry:
A leading European steel manufacturer introduces SpecMetrix in 2023 ® Online film thickness analyzer for real-time quality control of its coating production line.
After importing the system, the customer successfully controlled the average coating thickness from 8 μ m to 6 μ m through precise measurement and data feedback. This not only optimizes material usage, but also significantly reduces resource waste. For every 2 μ m reduction in spray thickness, customers can save approximately 40000 euros in coating costs per month, achieving significant economic benefits while improving production line efficiency.
🔹 A steel mill in East China:
As a pioneer in the transformation of intelligent manufacturing in China, a well-known steel enterprise in East China has installed a total of 6 sets of SpecMetrix on its 3 color coating production lines ® Online film thickness analysis system, covering key process links.
The measurement data is uploaded in real-time to the central monitoring center of the factory through a high-speed transmission protocol, achieving dynamic control and full process traceability of coating thickness. This measure not only improves the consistency of coating quality, but also lays the foundation for enterprises to establish a digital quality management system. Currently, the system has been further promoted as a model project in the steel industry.
🔹 Toyota US factory:
At Toyota's spray coating production line in the United States, SpecMetrix ® The film thickness analysis system has been fully deployed at key vehicle inspection stations. Each vehicle is equipped with 4 measurement points, all of which are automatically detected for film thickness by robotic arms, achieving non-contact, high-speed, and non-destructive measurement of car paint coatings.
Compared with the traditional manual inspection that takes several minutes per vehicle, SpecMetrix ® The introduction of has improved the measurement efficiency to complete the evaluation of the overall film thickness quality within seconds, greatly shortening the production cycle and effectively enhancing the degree of production automation and quality control accuracy.
In addition, SpecMetrix is widely used inPCB、 Lithium batteries, household appliances, metal packaging, flexible packaging, and coating research and developmentIn the industry, it has become the industry standard configuration for "film thickness intelligent control" in intelligent manufacturing.
Facing the future, film thickness dataWill become the 'fuel' for AI painting decision-making
As the manufacturing industry rapidly advances towards intelligence and refinement, how to achieve real-time monitoring and precise control of key process parameters has become the key to enhancing the core competitiveness of enterprises.SpecMetrix ® Film thickness analysis systemWith its non-contact, non-destructive, and sub micron level measurement capabilities, it is constantly breaking the technological limits of surface detection.
While ensuring product quality consistency, SpecMetrix can also deeply integrate with AI systems to provide real-time feedback on inspection data, drive process optimization, and build a truly intelligent measurement loop. In the future, industrial physics will continue to collaborate with partners from various industries,Jointly promote the intelligent upgrade of coating quality management, making every micron more controllable, efficient, and intelligent.
