In the quality control of manufacturing industry, coating thickness detection is a key link to ensure product performance. A domestic precision parts enterprise has long supplied electroplated and painted parts to the automotive and electronics industries. Previously, due to outdated traditional testing methods, it was plagued by low efficiency, large errors, and difficult traceability. It was not until the introduction of the AG-661 high-precision metal coating thickness gauge that the detection capability and product quality were upgraded.

The core products of this enterprise, such as automotive engine connectors and electronic sensor housings, have strict requirements for coating thickness. The zinc plating layer needs to be controlled at 8-12 μ m, and the paint layer needs to be stable at 20-30 μ m. Deviation exceeding ± 2% may affect corrosion resistance and service life. Previously, manual sampling and vernier caliper testing were used, and only 200 samples could be tested in a single day, resulting in low efficiency; Moreover, manual operation is prone to misjudgment and missed inspections, which increases rework costs and also poses risks to customer cooperation. More importantly, the detection data relies on manual recording and cannot be systematically stored and analyzed, making it difficult to trace quality issues and seriously hindering quality improvement.

In response to the pain points of enterprises, the AG-661 from AG-661 provides solutions based on three core advantages: firstly, high-precision adaptation to multiple needs. Equipped with F1/N1 dual probes, F1 can detect non-magnetic coatings on magnetic substrates such as steel, while N1 can detect insulation coatings on non-magnetic substrates such as aluminum and copper. The measurement range is 0-1250 μ m, with a resolution of 0.1 μ m and an indication accuracy of ± (2% H+1) μ m, meeting micrometer level detection requirements; The contact parts of the probe are made of hard chrome plated or ruby material, and the daily detection of 500+samples still maintains stable accuracy. Secondly, enhance intelligence. Support automatic recognition of probes and one click calibration, eliminating the need for complex training for detection personnel. The single person daily detection efficiency has been increased to over 800 pieces, which is 300% higher than traditional methods; It can also set upper and lower limits, and automatically beep and light an alarm when it exceeds the range, intercepting non-conforming products in real time. Thirdly, strong adaptation covers multiple scenarios. The aluminum shell is compact and portable (115mm × 67mm × 31mm), resistant to vibration, impact, and electromagnetic interference, and can be used in both laboratories and workshops; Powered by two No. 5 batteries, the battery can last for over 200 hours without backlight, ensuring continuous operation. In addition, AG-661 can store 500 sets of data (100 measurement values per set), and with USB interface and software, it can achieve automatic data storage, statistical analysis, and report printing, solving the problem of traceability.

After introducing AG-661, the coating inspection qualification rate of the enterprise increased from 92% to 99.5%, reducing rework losses by over 500000 yuan annually; The detection efficiency has been increased by three times, labor costs have been reduced by 40%, and the order has been successfully approved by the customer. The quality manager of the enterprise said, 'AG-661 is a good helper for quality upgrading, and the after-sales guarantee of AG-661 also gives us peace of mind.'. ”

AG-661 has served multiple fields, and in the future, we will continue to innovate and provide reliable testing solutions for more enterprises.
