Now widely used in various industries, online thickness gauges include
The coating thickness itself is invisible, but the coating thickness plays an important role in the coating properties, such as coating color. Inconsistency in coating thickness leads to mismatch in coating color. Therefore, in order to match the color of the parts, it is necessary to Control coating thickness. If the coating is too thin, it will cause the substrate to be visible; if the coating is too thick, it will affect the gloss, smooth surface and texture of the product. For protective coatings, if the coating is too thin, it will easily cause the coating to peel off and fail to protect the mechanical parts.
Coating thickness is very important. Commonly used coating thickness measurements include microscopes and contact thickness gauges, but these can only be used for contact thickness measurement after the coating is cured. There are many factors that affect coating thickness, such as changes in temperature, humidity and coating equipment, which can lead to process deviations.
The traditional coating thickness measurement method is to control the coating process at the back end of production and measure the coating thickness of the cured sample. If the parts are large, you need to wait for several hours of cooling time. If you use a microscope To measure the coating thickness of a sample, it will take several days to get the measurement results. If the coating process does not meet the requirements, large batches of rework will be required, which will increase powder consumption.
Therefore, continuous real-time non-contact measurement of the coating thickness of moving workpieces in the production line is very critical. Real-time process control is achieved through the Tuomaishi online thickness gauge. The ATO photothermal method can be used to measure the non-contact and non-destructive thickness of early coatings at the front end of the production line. Measurement, the coating thickness can be measured in just a few seconds, reducing rework and scrap, increasing production efficiency by 5% and reducing powder consumption by 30%.
