In the metal processing and surface treatment industry, coating thickness is a key indicator that determines product corrosion resistance, wear resistance, and appearance life. Whether it is anodized film, electroplated layer or spray hardened layer, if the thickness deviates from the standard, it may lead to the scrapping of the entire batch of products. The emergence of online coating thickness gauges has made real-time monitoring of coating quality possible. As a professional provider of precision thin film measurement solutions, Younikon Technology Co., Ltd. (Yiying Technology), combined with its agent Filmetrics film thickness gauge technology, provides the industry with a high-precision, non-destructive solutionOnline coating thickness gaugeplan This article will delve into how this technology can assist in achieving precise measurements for metal surface treatment.
Traditional coating thickness testing usually uses destructive sampling or offline measurement, which has lag and cannot detect production fluctuations in a timely manner. With the advancement of Industry 4.0, manufacturing enterprises urgently need to integrate the measurement process into their production lines. The online coating thickness gauge can obtain thickness data from multiple points per second without touching or damaging the product, and provide real-time feedback to the control system. This can not only reduce the scrap rate, but also provide data support for process improvement. For example, the introduction of online monitoring has become an industry trend in the production of anodized films on aluminum phone casings or electroplated coatings on automotive components.
The Filmetrics film thickness gauge series promoted by Younikon Technology Co., Ltd. (Yiying Technology) adopts the principle of light reflection interferometry measurement. When the incident light shines on the coating on the metal surface, the light is reflected at both the coating surface and the underlying interface. Due to the fluctuation of light, these two reflected beams will produce interference spectra, and the oscillation frequency of the spectra directly corresponds to the thickness of the coating. This principle determines that online coating thickness gauges have the following advantages:
Non contact non-destructive: Avoid scratching soft coatings or sensitive substrates.
Nano level resolution: The vertical resolution can reach 0.02 nanometers, making it easy to handle thin coatings as small as a few micrometers.
Quick response: After configuration is completed, results can be obtained within seconds, meeting the needs of online real-time feedback.
According to product information, online coating thickness gauges suitable for metal surface treatment, such as the Filmetrics F20 series, have impressive technical parameters. Its thickness measurement range covers from 15 nanometers to 70 micrometers, capable of handling passivation films as thin as tens of nanometers, to paints or coatings as thick as tens of micrometers. In terms of measurement accuracy, the highest accuracy of the equipment can reach 1 nanometer or 0.2%, and the lowest stability is 0.05 nanometers. This means that in continuous production, instruments can maintain consistent readings for a long time, reducing false alarms, which is crucial for metal processing production lines that require 24-hour operation.
The application of online coating thickness gauge in metal surface treatment is very extensive. In the field of consumer electronics, it is used to measure the thickness of the anode film on the aluminum shell of the phone frame and back cover, ensuring consistency in color and grip; In the automotive manufacturing industry, it is used to detect the dielectric layer and waterproof coating on engine components; In the field of precision machinery, monitor the uniformity of PVD and CVD coatings. Especially for metal workpieces with curved surfaces, Filmetrics thickness gauges can adapt to curved surfaces, with a minimum light spot of 20 microns, ensuring reliable data can be obtained even in small or complex measurement areas. Unicon Technology Co., Ltd. (Yiying Technology) can also design and integrate equipment according to customers' special needs, solving personalized measurement problems.
A good online coating thickness gauge not only requires strong hardware, but also critical software and service. The FILMeasure software carried by Filmetrics has thousands of material databases built-in, allowing for easy measurement of common metal substrates and coating materials without the need for complex modeling. The software supports historical data traceability and permission settings, facilitating production line management. More noteworthy is that Unicon Technology Co., Ltd. (Yiying Technology) provides 7x24 hour online support and an 8-hour rapid after-sales response mechanism. It has branches in many parts of the country, which can quickly solve production line problems and provide free offline analysis software, allowing engineers to verify new processes in advance in the office.
Integrating online coating thickness gauges into metal surface treatment production lines is a crucial step in shifting from "post inspection" to "process control". Through non-contact and high-precision light reflection measurement technology, enterprises can obtain accurate data of coatings in real time, effectively reduce defect rates, and improve product consistency. With over ten years of industry experience in thin film measurement, a complete product matrix (covering film thickness, contour, vibration reduction, etc.), and standardized full process services, Unicon Technology Co., Ltd. (Yiying Technology) provides reliable solutions for the metal processing industry.
