Specialized wire spring testing

The requirements for compression, tension and torsion springs in applications such as automotive fuel injection systems or complex electrical switches sometimes makes it necessary to measure the properties of the springs with 100% inspection. We have special machines available to do this, sometimes integrated into the work process. Separate spring setting and testing machines can take care of a wide range of testing procedures as required:

Acquisition of force-displacement characteristics
High-precision length measurement and force measurement system
Integrated geometry measurement using a camera system
Fully automatic test sequence
Reliable selection
High testing performance

High-performance dynamic fatigue test systems are available for testing the service life of wire springs and the fatigue strength of spring wires.

High-speed test machines for testing service life
Simultaneous testing of multiple springs
Variable test frequency
Different amplitudes (lift height)

Surface testing

Inspection of surface, shape and hardness

Traditional and computer-aided contour and hardness tests
Traditional and computer-aided contour and hardness tests
Microscopic surface examination

Test and fatigue test facilities

Springs often have to meet a complex requirement profile. In addition to the minimum requirements with respect to life cycles, the spring behavior must also tested under conditions similar to the application for which it is intended. To do this, we develop dedicated testing systems in consultation with our customers,which are often designed to determine the number of load cycles until failure of the spring or to demonstrate that a guaranteed minimum number of cycles can be met.

In serial testing, we ensure high levels of quality through continuous spot checking and control.

Quality of springs

MEDER has a consistent approach to quality, from product development through to final inspection and shipping. Modern methods of quality planning, such as APQP and FMEA, are used extensively to support the planning process. Test planning is integrated into the planning process during the product development phase. The in-process tests for products are derived from the control plan. Our machines and test equipment can meet complex testing requirements. At the end of the manufacturing process, our high quality levels are documented in the final inspection to ensure their traceability.

We design our production workplaces in accordance with ergonomic principles, and ensure that the most important product features are tested during the production process.

Our first-class supplier ratings testify to the success of our quality assurance strategy.

Quality of stamped and stamped-bent parts

MEDER has a consistent approach to quality, from product development through to testing during production and shipping. Modern methods of quality planning, such as APQP and FMEA, are used extensively to support the planning process. Test planning is integrated into product development. The in-process tests for products are derived from the control plan. Our machine and test equipment engineers can meet the specific testing requirements for every workpiece, including poka-yoke solutions where appropriate. The quality data is archived in the CAQ system and available for tracing when required.

We design our production workplaces in accordance with ergonomic principles, and ensure that the most important product features are tested during the production process.

Residual dirt analysis

In modern precision mechanical systems, the avoidance of dirt and particles is of great importance. In these systems, the smallest movements could potentially be blocked, lead to failure of the system. Given that these systems are closed and designed for lifetime use, subsequent cleaning is no longer possible.The residual dirt analysis serves two purposes: to detect and eliminate potential causes of dirt, and to provide evidence to the customer that the shipped components are clean.

There are a wide range of testing requirements, both national and international. We adapt to customer-specific test variants.

The test results are documented and assessed in accordance with specified criteria such as VDA Volume 19.

Risk management (FMEA)

At MEDER, FMEA plays an important role. An early and systematic feasibility analysis is carried out during the tendering stage. The use of FMEA is designed to identify and avoid potential sources of error at an early stage.

Computer-aided image processing systems

Our hardware and software specialists adapt geometry control by high-resolution vision systems with specific lighting systems to each particular application.

Our in-line process monitoring or 100% final inspection has a cycle time neutral repeat measurement accuracy of a few microns.

We use laser-based measurement processes for sampling, for in-line process control or for 100% final inspection.
