Company history

Our corporate culture comes from the family company Exacta Normalia d. o. o. and is embedded in the environment from the beginning to the present. The notes of today's Exacte Normal d. o. o. go back to 1982 when Lado Prešern, after 17 years of working and living in Germany, decided to return to Slovenia, more precisely to his birthplace - Žirovnica. In 1982, he set up his workshop in his home as a toolmaker and continued his work in Germany. The sons Robert and Thomas assisted his work. The first stand-alone equipment was modest. Over the years, we have been perfecting, developing and adapting to the customers on the market. In 2012, with the construction of our business facility in the business center Žirovnica, we increased the production as well as the scope of operations. In all these years, we have developed into a recognized, high-tech specialized company. Today, the company has more than 10 employees.
