Niefern-Öschelbronn, 21.07.2026 – Last Friday, we gathered at our headquarters in Niefern to celebrate 100 years of innovation, growth, and togetherness.

The festivities opened with a speech by our Managing Director, Mr. Sihn. He not only reflected on our impressive history of success, but also shared an inspiring vision for the future chapters of our company.

Alongside delicious BBQ catering and refreshing treats from the ice cream truck, the day was all about connecting and catching up. A highlight was the various guided tours: whether exploring our Automotive division, Product Management, or our Warehouse, both team members and their visiting friends and family took the opportunity to get a behind-the-scenes look at our daily work across different departments.

A memorable group photo captured the incredible team spirit of the day. It truly represents what has defined WISI for a century: strong unity, passion, and a shared drive to push innovation forward.

A heartfelt thank you goes out to all employees, guests, and especially the organizing team and many volunteers whose hard work made this anniversary celebration possible.
