SARIV: automotive best practice at Würth world SQE Conference
SARIV was chosen by Würth as a global best practice case for custom blind rivet solutions in the automotive sector.
We are proud to announce that SARIV has been selected by Würth as an international best practice case study in the field of customized blind rivet production for the automotive sector. Our expertise was presented at the annual SQE Conference, an event that brings together Supplier Quality Engineers from Würth companies across the globe, including Germany, Italy, France, Slovakia, China, Taiwan, India, Vietnam, the USA, and Brazil.
A Best Practice in Contract Review Management
During the event, Würth showcased our approach to contract review management, using as a case study the project developed with a major automotive customer: the supply of a single rivet for five different applications within a rear-seat sunshade winding mechanism.
Our contribution was recognized as best practice in managing technical complexity and product customization, in a context where flexibility and reliability are crucial to ensuring the quality of the final product.
✔ ONE RIVET, FIVE CRITICAL APPLICATIONS
The project involved five distinct application points, each with specific technical requirements, varying thicknesses, and different materials:
1. Bearing block to metal sheet
2. Gearbox housing to metal sheet
3. Push rod to articulated arm
4. Push rod to output plate
5. Articulated arm to tie rod
✔ REQUIREMENTS AND TECHNICAL SOLUTIONS
The project required a high-performance solution, capable of adapting to various combinations of materials and thicknesses, without compromising on either functional or aesthetic quality. Key requirements included:
No dust formation or coating detachment during assembly
No visual contamination (e.g., staining on white surfaces)
Resistance to 25,000 opening/closing cycles and tensile loads up to 2,500 N
Our first proposal was a stainless steel structural rivet with a burnished head, ensuring high load resistance and a clean black finish.
Following the first assembly tests by the customer, which revealed some critical issues at two of the five application points, SARIV proposed an improved second solution: a multigrip A2 stainless steel rivet with a round head, a dedicated grip range, and a surface coating either burnished or black Zn/Ni treated. This provided a precise response to the critical tolerances identified in the assembly process.
✔ A RECOGNITION THAT CELEBRATES TECHNICAL APPROACH AND CO-DESIGN
Being presented as a technical and management best practice to such a prestigious international audience, by a global group like Würth, is a strong validation of our daily commitment to innovation, precision, and customer satisfaction.
A special thank you to the Würth team and all international colleagues in attendance for their trust and recognition.
