Quality
Certified standards as part of our strategy
Quality
In addition to our manufacturing processes, we develop test methods and equipment to ensure the quality of our products. From special testing facilities through development assistance to 100% inspection during the manufacturing process, we can provide a wide range of test equipment.
Create quality
- We want more than satisfied customers – we want to inspire our customers
- For us, quality is more than the product, quality is everything we do
- Quality is the responsibility of all employees
- Managers are role models for their employees
- We plan the product from development until the end of series production

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 deflection diagrams
- 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 life cycle of wire springs.
- High-speed test machines for testing service life
- Simultaneous testing of multiple springs
- Variable test frequency
- Different amplitudes (stroke)
Testing of the surface, shape, hardness and microstructure
- Traditional and computer-aided contour and hardness tests
- Microscopic surface examination
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. These practical tests are supported by the latest statistical methods (e.g the Weibull method).
In serial testing, we ensure high levels of quality through continuous sampling and control.
BOHNERT 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.

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.

To monitor the processes, we use the relevant test methods specified in AIAG CQI-9 for heat treatment.

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.
At BOHNERT, FMEA plays an important role. A 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.
Our hardware and software specialists adapt geometry and surface 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.
