Mario Leitner, Founder
After graduating from the technical school for mechanical engineering in Zeltweg, he began working as a production employee, more precisely as a fitter and welder, where he learned what hard manually work means. Later, he worked on CNC machines, responsible both for programming the machines and for manufacturing the parts in series production.
Many years as a designer for various design and engineering products followed. There he was able to acquire extensive knowledge in mold making and design for injection moulding, die casting, stamping and sheet metal parts. In recent years he has worked for an Austrian FSW machine manufacturer as a sales and key account manager. However, he also worked as a consultant directly with customers, e.g. for well-known German OEMs, for technical development, part design and as a pioneer for innovations.
What distinguishes him is that he has an extraordinarily broad theoretical knowledge coupled with many years of development and production experience in series production. Because of this, he was always welcome by his customers.
His credo: "His customers are repeat buyers!"
