TECHNOLOGY ADAPTED FOR FAST PACE INPSECTION OF DOOR SYSTEMS
EZMetrology delivers fast, intuitive, and reliable inspection solutions designed for the realities of high-volume automotive manufacturing. Whether you need a quick quality check or a full diagnostic assessment, our software technology adapts seamlessly to your workflow, ensuring confidence in every closure, every time.
Our technologies are engineered for speed, operator simplicity, and robust production use, while capturing high-resolution motion and force data essential for traceability.
The system can be configured to track any single parameter or a complete suite of door performance metrics depending on the plant’s requirements.
- Closing Speed – Verifies profile across the closing event.
- Closing Energy – Measures kinetic energy and system efficiency.
- Hinge Tip – Determines geometric deviation and hinge alignment.
- Friction – Evaluates resistance in motion and component interaction.
- Striker Alignment – Confirms target alignment for optimal latch engagement.
- Window Penetration – Assesses glass and weatherstrip interface behavior.
Inspection stations operate in full connection with our Production Line Software (PLS), eliminating manual data entry and ensuring consistent, guided processes. Operators stay focused on the process, not the interface. Each inspection begins with automatic vehicle identification via barcode or PLC.
Our Production Line Software (PLS) instantly loads the correct model and guides the operator step-by-step through the routine.
Data flows automatically into your quality systems so statistical trends and production tendencies can be monitored with ease.
This creates a seamless, error-free inspection chain across the production environment.
Once the VIN is received:
1. PLS automatically loads the correct vehicle model.
2. A model-specific inspection routine is deployed to the gauge.
3. The operator is guided through a step-by-step workflow with no keyboard interaction.
4. Measurement results are automatically sent back to PLS.
5. PLS forwards results upstream for statistical analysis, SPC, or vehicle-level quality validation.
- File Export (CSV or similar text formats)
- TCP-IP Communication
- Direct Database Write Access
For high-speed production environments, inspection can be simplified to a single “Pass” or “Fail” decision. A fast reading confirms whether the closure meets the required standard ideal for stations with only seconds available.
When cycle time is extremely limited, the inspection can be optimized to deliver a rapid Good/Bad verdict.
A single reading can validate whether a vehicle meets the performance ideal when only a few seconds are available per closure.
Depending on the available cycle time, the inspection methods can be adjusted.
This ensures maximum throughput while maintaining strict quality gates.
Thresholds, tolerances, and validation windows are fully configurable per model.
Thresholds, tolerances, and validation windows are fully configurable per model.
- Shortest possible cycle time
- 100% outgoing inspection coverage
- Immediate validation of critical characteristics
For stations with more available time per door, the system can record the true, continuous value of parameters such as minimum closing speed, force, or dynamic energy.
True value inspection requires a short sequence of samples, enabling the software to calculate real performance metrics rather than threshold-based judgments.
While marginally longer, this process yields significantly higher diagnostic value and supports complete statistical control.
This mode is ideal for lines focused on continuous improvement and engineering analysis.
- Absolute performance measurement
- Trend and drift monitoring across production shifts
- Deep process control and Cpk capability
