In-Line Test Benches
Process-Integrated Quality Assurance at Production Cycle Speed
From isolated measurement stations to cycle-time-optimized testing units – we develop in-line systems that not only monitor your production, but actively control it.
In highly efficient serial production, end-of-line testing is often too late to prevent costly scrap. WSK Elektronik implements in-line test benches that are directly integrated into your material flow. With over 30 years of expertise in special machine engineering and measurement electronics, we build systems that validate physical parameters exactly where they occur – for quality assurance without time loss.
Real-Time Feedback for Minimal Scrap Rates
In modern manufacturing, in-line testing is the decisive early warning system. An error in the assembly process must be detected immediately before the component passes through further cost-intensive stages. WSK Elektronik understands in-line testing as a combination of maximum cycle-time synchronization and absolute signal precision.
We build testing systems that are seamlessly integrated into your conveyor technology and, through intelligent measurement chains, ensure that every process step is validated within milliseconds. This creates the foundation for proactive process control and sustainably minimizes your scrap costs.
Seamless Integration & Cycle Time Optimization
To avoid slowing down your production flow, measurement cycles and mechanical interactions must be perfectly synchronized.
Our in-line systems utilize high-performance architectures to efficiently execute complex testing profiles:
Cycle Time Synchronization
We integrate haptic, electrical, or media-based testing into your production line flow so that validation is performed within your defined cycle times.
Automated Adaptation
Use of fast pneumatic or servo-driven contacting systems that fix the test specimen within the ongoing production flow and establish contact without manual intervention.
Early Fault Detection
Immediate feedback to the line control system (PLC) in case of limit violations, allowing defective parts to be removed directly after the process step that caused the error.
Dynamic Cycle Time Synchronization and Automated Contacting
The most critical risk in process-integrated systems is the shutdown of the entire production line due to sensor failure or data congestion. We address these challenges with the proven WSK architecture:
- Precision Measurement Electronics: Use of hardware that precisely isolates and digitizes even the smallest analog signals, even under severe industrial interference conditions.
- The WSK Software Framework: Our systems are based on a modular C# / C++ architecture that guarantees deterministic real-time behavior and maximum data security in continuous operation.
- Seamless SQL Archiving: All in-line captured measurement data is stored directly in databases, enabling immediate trend analysis and proactive maintenance of production equipment.
Your Path to an Integrated In-Line Test Bench
The development of a process-integrated testing station is an investment in your zero-defect strategy. Within our proven 6-step process for customized test systems, we place special emphasis on mechanical and digital integration in in-line projects:
- Specification of Integration Interfaces: We analyze your production flow and define the physical and software-based handover points to ensure seamless communication with your conveyor system and PLC.
- Design of a Cycle-Time-Optimized Environment: We develop the complete integration of the measurement chain within your installation space, including necessary quick-change systems for different product variants.
- Automation of Data Feedback: We implement algorithms that make IO/NIO decisions in real time and transmit the results directly to your MES or ERP system.

Frequently Asked Questions about Our In-Line Test Benches
We optimize testing algorithms within our WSK framework for maximum speed and utilize parallel processing. If the measurement time exceeds the production line cycle time, we design diverter systems or dual testing cells to maintain a consistent production flow.
In such cases, we implement parallel testing stations or bypass solutions where components are diverted, tested, and then reintegrated into the production flow. Our goal is to integrate quality assurance in a way that increases OEE (Overall Equipment Effectiveness) rather than slowing down throughput.
Yes. By integrating camera systems or RFID readers, the test bench automatically identifies the variant and loads the corresponding test parameters from the database. Mechanically, we often use universal adapters or modular quick-change plate systems.
We implement seamless communication via standardized industrial interfaces such as Profinet, EtherCAT, or OPC UA. This ensures that IO/NIO signals and process data are exchanged between the test bench and the production line without delay.
Industrial environments with frequency converters and motors pose a significant challenge for measurement signals. We use EMC-optimized control cabinet designs and hardware with extremely low temperature coefficients to isolate signal noise and ensure stable, drift-free data directly within the process flow over many years.
We implement a seamless data chain via industrial interfaces such as OPC UA or Profinet. This allows the PLC to receive an IO/NIO signal for sorting in real time, while detailed physical measurement data is simultaneously transferred to your SQL database for trend analysis.
