The end-of-line tester reliably ensures quality in mass production. Precise leak tests, comprehensive functional tests, and flexible changeover capabilities enable its use with a variety of test specimens and sustainably increase efficiency and process reliability. # Challenges and Concept ![](https://mcd.site team.de/wp-content/uploads/2026/07/Inliner-Ringmagnet-EOLT-scaled.jpg) ![](https://mcd.site team.de/wp-content/uploads/2026/06/Group_30131.svg) The inline testing system was specifically developed for the automated assembly and testing of mechatronic components. It combines the precise assembly of sealing rings with comprehensive functional testing in a single, continuous process. As an end-of-line system, it enables seamless quality control directly on the production line. At the first station, a sealing ring is installed, followed by a leak test using vacuum and differential pressure methods. The second station then performs the functional test, during which electrical and mechanical parameters—such as torque, angle, current curves, and signals—are precisely recorded and evaluated. The automated material flow and flexible adaptability to different types of test specimens ensure high efficiency and process reliability. # Scope of Testing and Functionality ![](https://mcd.site team.de/wp-content/uploads/2026/07/Inliner-Beleuchtung-EOLT-1024x768.jpg) ![](https://mcd.site team.de/wp-content/uploads/2026/06/Group_30131.svg) The inline system consists of two coordinated stations designed to implement a fully automated testing process. The first station performs the automated installation of the sealing ring onto the test specimen shaft, followed by a leak test using vacuum and differential pressure methods. This combination enables leaks to be detected and measured with high sensitivity and reproducibility. The second station is used to perform a functional test on the test specimen. To do this, the test specimen is secured, connected to the test equipment, and operated under defined test conditions. A specially developed load motor simulates the mechanical loads on the test specimen and enables angle measurements with an accuracy of less than 0.1°. During the test sequence, measured variables such as torque, angular position, current curves, and sensor and signal data are continuously recorded and evaluated. The system’s design ensures high reproducibility of the measurement results as well as high process reliability. - Installation of the Sealing Rings - Leak Testing Using Vacuum and Differential Pressure Methods - Measurement of the travel angle (<0.1°) - Torque Measurement - Current Profile - Hall Sensor Calibration and Adjustment - Simulation of Different Loads - Analysis of Sensor Data - MES Integration # Test Methods Used and Results ![](https://mcd.site team.de/wp-content/uploads/2026/07/INLINE-SYSTEM-mechatronic-components_mcd-002-1024x1012.png) ![](https://mcd.site team.de/wp-content/uploads/2026/06/Group_30132.svg) The inline test system features high-performance technical equipment for the precise testing of mechatronic components. This includes motor control systems, flexible I/O modules, and multifunction cards for signal processing. Powerful test software enables comprehensive data acquisition, evaluation, and traceability of all test results. Automated handling is provided by feeding, sorting, and transfer systems that ensure a continuous flow of material. Leak testing is performed using high-precision measurement technology, while all test and process data are stored centrally. This ensures a high level of quality assurance, repeatability, and transparency throughout the entire testing process. ## FREQUENTLY ASKED QUESTIONS ### FAQS What is an inline testing system for mechatronic components?
