More than just joining – Assembly with WITOL

Demanding assembly situations in the automotive industry require innovative solutions that create reliable connections – even in a highly automated production environment. Tolerance management in particular can be a challenge for car manufacturers, which we can solve individually for our customers with our WITOL tolerance compensation elements.

Assembly tolerances – what now?

One of the main reasons for using tolerance compensation elements are assembly tolerance problems that can occur during the final assembly of vehicles and lead to delays, quality defects and rework.

Adherence to cycle times is a critical factor in final assembly and can lead to difficulties due to a lack of tolerance management in the joining process. With active tolerance management and the use of WITOL tolerance compensation elements, assembly tolerances can be reliably compensated. Cycle times can be adhered to and the need for time-consuming readjustment is eliminated.

Size, weight and the increasing complexity of the functionalities of individual components also have an impact on assembly and the joint pattern. In this context, tolerance compensation elements from WITOL play a decisive role by reliably compensating for component tolerances during the fastening process.

Furthermore, WITOLs offer high repeatability and robustness in the assembly processes. They enable consistent and reliable assembly, regardless of the varying tolerances of the individual components. This further improves the quality of the end products and reduces rejects.

Another decisive advantage is the tool-independence of the tolerance compensation elements. This creates flexibility in assembly, as they can also be used in automated processes without having to rely on specific tools. Productivity can be further increased by implementing automated bolting processes.

Another important aspect is the ability to use WITOL tolerance compensation elements for blind installations. This means that even highly complex installation situations can be handled effectively.  With a visually perfect fastening, a tension-free connection and optimized overall costs by avoiding reworking as the customer-perceptible result.

Noise, vibration, harshness – avoid interference!

Customers also use WITOLs to reduce NVH and specifically mitigate noise levels through anticipatory tolerance compensation. The issue of NVH is becoming increasingly relevant, especially in the new generation of electric vehicles, as noise in the comparatively quiet passenger compartments is perceived as disturbing. By using intelligent WITOL solutions, we can help to effectively compensate for tolerances on two components to be connected so that disturbing noises caused by natural frequencies are avoided while driving. This in turn has a positive effect on the driving experience and overall customer satisfaction.

Highest demands on the overall aesthetic concept!

The visual appearance and overall aesthetic appeal play just as important a role in the use of tolerance compensation elements as efficient installation.  Optimum joint gaps also increase the unconscious perception of quality.

The result is not only a tension-free connection, but also a flush surface that meets the highest visual and tactile demands.

Flexible and efficient: individual solutions from WITOL

Customer-specific requirements demand a thorough analysis for optimum solutions.  Flexibility is a key aspect of the way we work – especially when the available installation space for our WITOLs is limited.

Our approach is based on a conscientious analysis that enables us to get a precise idea of the challenges to be expected in order to integrate our tolerance compensation solutions in the best possible way.

At WITOL, we focus on innovation, precision and customer satisfaction.
