It is not easy to measure the coating thickness of a flat surface, and it is even more difficult to measure the coating thickness of a complex geometric surface structure. Traditional single-point contact measurement often cannot meet customer needs. This method is usually quite inaccurate, and it is only suitable for coating thickness measurement after curing, and cannot support coating thickness measurement during the production process.
In order to realize the coating thickness of the complex geometric surface structure, based on the excellent ATO photothermal method technology, Tumoshi Online Paint Film Thickness Gauge has developed a method that uses the difference in thermal properties between the coating and the substrate to measure the coating thickness. non-contact non-destructive measurement system. Tumoshi paint film thickness automatic detection system is suitable for powder spraying, which can accurately detect the thickness of powder coating and stabilize the quality of spraying process; it is suitable for wet film and dry film application, and can accurately detect wet film coating before curing and obtain dry film immediately Thickness, time saving and stable quality etc.
Through the survey, 50% of people manually measure the coating thickness after the curing or drying process, 43% measure the coating thickness manually in a quality assurance laboratory, and 21% choose to manually measure the coating thickness before the curing and drying process. Measuring coating thickness, however, no one is using automated instruments to measure coating thickness and optimize the spraying process.
From the survey results, most people choose to use a contact coating Thickness Gauge at the end of the production line to manually measure the thickness of the cured coating. However, whether it is a wet film or a dry film, the coating thickness measurement is performed at the end of the production line It is already too late, if the measurement effect is not good at this time, a large number of defective products will be produced, which needs to be reworked, which will lead to more consumption of funds, manpower and material resources.
Tumoshi non-contact non-destructive thickness measurement system can measure the coating thickness in the early stage of the production line, record the continuous data of the coating process for you and your customers, and provide a basis for optimizing the process and replacing consumables; it can reduce material consumption; provide High-precision production conditions, timely analysis of film thickness data, timely detection of failure problems such as Spray Gun clogging, and assistance in adjusting process parameters.
How to measure coating thickness before curing?
Tumoshi online paint film thickness measurement system uses the principle of ATO photothermal method to heat the coating to be tested in a pulsed manner by controlling the light source through a computer. The built-in high-speed infrared Detector records the temperature distribution of the coating surface from a distance and generates a temperature decay curve. . The decay time of the surface temperature depends on the thickness of the coating and its thermal conductivity. Finally, the specially developed algorithm is used to analyze the surface dynamic temperature curve to calculate and measure the coating thickness to be measured.
Tumoshi paint film thickness automatic detection system product series introduction
Tumoshi paint film thickness automatic detection systems include FLEX handheld, Inline online, Atline laboratory, and 3D overall film thickness imaging system.
Tumagist Handheld Coating Thickness Gauge FLEX is a high-precision non-contact non-destructive thickness measurement system with complete functions, no need for integration, easy operation, simple calibration, no need to strictly control the test distance and angle, no need to wait until the coating Coating thickness measurement is performed after curing, which can effectively save materials and avoid coating defects. It is suitable for production workshops and automatically records data and the entire production process.
After using the hand-held coating Thickness Gauge FLEX to monitor the powder spraying film thickness on the production line, the powder output can be adjusted to save 30% of the powder. Especially for small batches, the product has been sprayed before it comes out of the oven, so the film thickness cannot be adjusted according to the dry film. However, the magician can adjust the powder output within a few minutes of spraying, reducing rework and reducing costs.
Tumoshi 3D overall film thickness imaging system, through 3D imaging detection technology, can easily and non-contact accurately measure the film thickness distribution of parts with complex shapes. The data of the test point corresponds to the measured part of the workpiece one by one, and the film thickness can be effectively monitored in real time. The true situation.
Why is it necessary to measure overall coating thickness?
By using Tumoshi 3D overall film thickness imaging system to measure the coating thickness, the coating distribution can be clearly seen, and the film thickness of the moving workpiece on the production line can be continuously detected in real time without strict control of the measurement conditions. Inner wall, three-dimensional, edge, etc.), workpieces of various colors (not limited by light colors such as white) can also accurately measure the thickness. The automatic control of the coating line is realized through SPS and other interfaces, and the Tumoshi 3D overall film thickness imaging system can be easily and effectively integrated into the existing coating line, and the integration cost is low.
Tumoshi 3D overall film thickness imaging system measures the coating thickness of complex geometric surface workpieces, and can obtain information on about 100,000 measurement points on the surface within half a second, which makes the measurement of complex surface coating thickness simple, and through the Record and archive the measurement results and adjust the process in time to achieve effective control of the quality of the spraying process.
