The name Cetto looks back on a long history.
The community of Saal an der Donau and the name of the commercial councilor Ernst Cetto are inextricably linked, as the place owes its upward development to today's “industrial community” to him.

Born in 1880, Kommerzienrat Ernst Cetto was director and owner of the lime works in Saal, Kelheim and Ismaning near Munich and employed 1,500 people. He built workers' settlements, schools, kindergartens, streets, open-air swimming pools, a war memorial and a church, as well as a hotel and in the 1920s ensured the early electrification by laying a power grid and a central water supply in the village. To further supply the citizens, he ran a wholesale and retail trade, which laid the foundations for today's Cetto group of companies.
After the Second World War, the demand for plastic was so high that his son Ernst Eugen Cetto took his chance in 1960 and converted the wholesale and retail trade into the company "Ernst Cetto Plastprodukte", which produced thermosetting and thermoplastic plastic items.
In the beginning, the first simple plastic parts such as pastille containers, wallpaper protectors and record stands were produced on a 100m² production area on a small injection molding machine that had to be operated by hand. In the course of time the company was expanded to include two more production halls and a tool shop.
In 1978, son Ernst Robert Otto Cetto took over the company with 35 employees and completely reorganized the company: in the future, customers from the electrical and automotive industries were to be won. This required extensive investments in additional specialist knowledge and machinery.
His strategy worked: he succeeded in expanding the company to a total of 7,000 m² and 150 employees, and through the implementation of new process technologies such as automation, overmolding of inserts, multi-component injection molding, and the start of the production of complete assemblies, such as Air flow meter to save fuel in vehicles, to develop the company into an innovative high-tech company.
With the establishment of cetto BOHEMIA sro he succeeded in establishing the company Cetto as an international company and implementing it as a permanent name on the world market for the automotive and electronics industry.
Today, well over 1 million plastic parts are produced in the factories every day, which are delivered to production facilities all over the world.
The generation change to the two children Alexandra and Maximilian took place in 2020, which ensures the future of the family business.
"For us, our company is part of the family. We are therefore proud that we have succeeded in making the generation change and leading the company into the future. "
