The expertise we have built up over more than 100 years, our highly qualified employees and our uncompromising commitment to quality make KUNDERT the leading partner for technical plastic components for industry, medicine and food. Machined parts, molded parts and coatings made of polyurethane, injection-molded parts and the wide range of semi-finished plastic products are among our core competencies.

As a Swiss family business since 1906, KUNDERT has a distinctly social and communicative corporate culture. The personal responsibility and innovative strength of our employees are specifically encouraged.

In 1906, Ernst Kundert Sr. founded the company, which subsequently developed over many decades into a leading trading company for accessories for the textile industry. At that time, weaving shuttles, spinning cans, spinning tubes and even bicycle handles and skis were sold.

Over the years, the company developed away from being a pure trading company towards manufacturing its own metallic gear wheels, plastic finished parts and polyurethanes.

Shortly after the start of the new millennium, the focus was placed entirely on the manufacture and processing of plastics and the production of metal gears was sold. This focus has made KUNDERT the leading Swiss supplier of finished plastic parts, semi-finished plastic products and polyurethanes.

KUNDERT Innovation Award

Innovation and creativity are very important at KUNDERT. Many employees contribute their ideas on a daily basis to improve processes, simplify production operations and make the company more efficient. The KUNDERT Innovation Award was created to encourage and appropriately reward this commitment, which goes above and beyond the norm.

In freely selectable groups, employees can document and evaluate innovative ideas and then submit them. A jury then selects the best of the submissions. The winning team receives a bonus for free disposal.


KUNDERT AG has had its own employee app since 2019. News and personnel announcements are published on this app. The app also has a chat function that can be used freely. Holiday photos are also shared on the pinboard, creating a lively exchange of experiences.

Company events

A job is not just about the actual work. The team also plays a key role. At several annual events, the focus is entirely on team spirit and interaction between colleagues. The summer party, the Christmas aperitif and the departmental dinners are fixed points in the calendar.
