Our Defect Inspection System includes two dedicated EOL testers. One is for automotive actuators with worm‑gear and screw drives. The other is for electronic controllers like PCBs and central control units. Both are modular and built for high‑volume production. They replace manual checks with automated, digital testing. The product gives you consistent results and removes human judgment errors. Each system supports full customization and MES data integration.
Ⅰ. Automotive Actuator EOL Tester (Door Actuator Model)
All‑in‑One Testing for Mechanical and Electrical Performance
This tester combines six test items in one machine: leak tightness, NVH noise, torque/pull force, electrical performance, displacement stroke, and assembly check. It has a quiet test chamber and a servo loading mechanism. It simulates real vehicle conditions accurately. The product works for door actuators, window lifters, seat drives, and HVAC dampers. It runs a full test cycle within 60 seconds, matching standard production takt time.
Precision Leak and Noise Testing
The system uses custom sealing fixtures and high‑precision pressure sensors. It detects air leakage from housings, gaskets, and joints. Accuracy reaches 0.1 Pa. Multiple pressure settings can be stored and switched. For noise, the enclosed silent chamber blocks workshop noise. Acoustic sensors capture gear, screw, and motor sounds. It outputs sound pressure, loudness, and frequency curves. This replaces human ear inspection with objective data.
Torque, Force, and Electrical Checks
A servo motor with torque and displacement sensors measures push‑pull force, running resistance, and stroke curves. It finds sticking, torque dips, or incomplete travel. For electrical tests, it applies standard voltage and reads no‑load/load current, motor voltage drop, Hall signals, and CAN/LIN bus data. It verifies motor smoothness and signal integrity. The product also checks assembly with vision and photoelectric sensors – it sees if shells, worms, screws, gaskets, or seals are missing, wrong, or loose.
Data Traceability and Quick Changeover
Each product is scanned by SN code. All test curves and values are saved locally and can be exported as CSV. It connects to your MES for full traceability. The system stores multiple test programs. After changing tooling, you just call up the new recipe. This supports flexible production of many actuator types.
Advantages and Applications
This Defect Inspection System is universal – it handles not only door actuators but also window regulators, seat adjusters, tailgate drives, and more. It integrates six tests in one station, saving floor space and labor. The silent chamber means you don't need a special quiet room. Tooling changeover is fast with standard locating pins. It has safety light curtains, overload protection, and standard components for easy maintenance. It is used by Tier‑1 suppliers for semi‑auto or full‑auto assembly lines.

Ⅱ. Electronic Controller EOL Tester
Automated Full‑Function Test for PCBs and Control Modules
This tester is designed for electronic controllers like infotainment units, HVAC modules, seat ECUs, and interior PCBs. It performs all required tests automatically – connector continuity, voltage/current, CAN/LIN communication, hardware functions, and system interaction. The product uses high‑precision probing pins and a dual‑station design. It tests two units at the same time, matching a 70‑second production cycle. It works with a 6‑axis robot for loading and unloading, and it sorts good and bad parts automatically.
Double‑Station Efficiency and Robot Sorting
The dual‑station fixture lets you test two controllers in parallel. This cuts the overall cycle time significantly. The robot picks each unit from the conveyor, places it in the test fixture, and after testing, moves good units to the next conveyor and bad units to a rework area. This fully automatic operation needs no operator. The Defect Inspection System also reads barcodes and RFID tags to link each test result to the product serial number. All data is stored locally and uploaded to MES in real time.
Flexible Recipes and Safety Protection
The system stores multiple test programs for different controller models. When you change the product, you simply select the new recipe and swap the fixture. The probing pins and connectors are adjustable. Safety features include light curtains, cylinder interlock, probe overload protection, and short‑circuit protection. The machine will not start if the part is not placed correctly, preventing damage to PCBs and connectors.
Advantages and Applications
This product is versatile – it suits not only automotive central controllers but also audio modules, seat memory units, climate panels, and other interior electronics. It can even handle consumer electronics or industrial control boards. The dual‑station design boosts throughput. The probing pins are high‑accuracy, giving very small measurement errors. All pass/fail decisions are made by software, eliminating human mistakes. It connects directly to your MES for smart factory management. Maintenance is easy because all components are standard off‑the‑shelf parts. This system is ideal for end‑of‑line testing in high‑volume electronics assembly lines.
