About Us
110 years of innovation in plastics
Plastics are our passion. Precision is our strength. In line with our motto “Innovation in plastics,” we have been developing smart solutions for the individual needs of our customers for generations.
All of our high-quality plastic applications are manufactured exclusively at our factory in Thun—100% Swiss quality and genuine craftsmanship instead of assembly line work. We place great emphasis on reliability, adherence to deadlines, and partnership-based cooperation.
Cellwar is an owner-managed company with strong roots and a clear vision for the future. Benedikt Zenhäusern works daily with his team of over 30 highly qualified and motivated employees on innovative solutions in plastics processing. To ensure a supply of qualified young talent and fulfill our responsibility, we train apprentices directly in our company.
Our unique expertise, modern technical equipment, and passion for our craft make us a reliable partner when it comes to sophisticated plastics solutions – today and in the future.
