at present, the traditional thickness gauge is very difficult to measure bending and small parts, and the data is inaccurate. The non-contact nondestructive film thickness analyzer with the leading photothermal ATO technology can solve this problem

in 2019, the German coating manufacturer OFTM (affiliated to scherdel group) needs to evaluate the best coating thickness measurement method for a batch of new small parts

after excluding a variety of thickness measurement methods, the company decided to use the coating magician ATO non-contact thickness measurement technology, which can quickly and accurately measure the coating thickness of parts even in small, complex, irregular, curved and other difficult parts

finally, the coating magic non-contact thickness measurement technology and its handheld non-contact film thickness analyzer (coating magic Flex) have become the best thickness measurement scheme for testing this part

figure above: non contact non-destructive measurement of the coating thickness of new parts is carried out by using Tu magician flex handheld non-contact film thickness analyzer

among them, EN ISO 2808 and EN ISO 3882 and other test standards detail the recognized film thickness measurement 1. Zero adjustment of dial pointer hydraulic (pendulum) universal testing machine: such as the measurement method of WE-B series digital display hydraulic universal testing machine, The test standards summarized in Table 1 below play a decisive role in OFTM's selection of the best thickness measurement method

oftm company eliminated several inapplicable measurement methods with the help of the above measurement requirements:

1 Considering the coating material of new parts, the β Measurement methods such as backscattering and X-ray spectroscopy

2. A series of complex collision avoidance thickness measurement experiments were carried out according to the type of substrate, which confirmed that the accuracy and repeatability of magnetic induction and eddy current thickness measurement methods were not good enough to meet the measurement accuracy requirements of automobile thickness measurement equipment

previously, most manufacturers used the traditional magnetic induction dry film measurement method for film thickness contact measurement. However, this thickness measurement method can only measure the film thickness after the coating is dried, and the measurement results are affected by the roughness, bending degree and edge effect of the coating surface

in order to make up for the shortcomings of the above thickness measurement methods, the non-contact accurate thickness measurement method based on advanced photothermal method (ATO) - Tu magician will be introduced in detail below

the coating magician adopts a non-contact nondestructive measurement method. The coating workers can immediately measure the film thickness before the product enters the oven and the coating is still in the uncured state, so as to obtain the dry film thickness in real time. There is no need to strictly control the measurement angle, measurement speed, acceleration, vibration and other parameters and distance during measurement, and the workpiece with complex and irregular shape can also measure the thickness accurately

with the help of high-precision and repeatable measurement data, coating manufacturers can effectively monitor the coating process and timely adjust multiple spraying parameters of coating equipment

the measuring principle of the coating magician is based on the short pulse heating of the coating surface to be measured, and the infrared sensor is used to measure the temperature attenuation curve, and finally determine the coating thickness quantitatively. The measurement data and applications of Tu magician flex are automatically stored in the cloud

manufacturers can use Tu magician flex not only for delivery quality supervision, but also for statistical process control (SPC). In addition, the coating magician can replace the time-consuming microscope thickness measurement method without losing samples. The coating magician can complete the test within 1 second, so it can be used for continuous film thickness measurement

in addition, using the coating magician can detect and monitor the film thickness of the coating process faster and more efficiently, minimize the fluctuation range of film thickness, maximize the optimization of production resources, and reduce production costs

even for parts with complex shapes, coating magician flex can accurately measure the coating thickness. Its simple and fast calibration and measurement advantages are our important coating quality inspection tools
