Our "More"-values

The most important objective for Managing Partner Armin Stolzer is to secure and shape the future of KASTO. To achieve this, his vision is a mixture of experience and new ideas. For a smooth transition into the future, he has brought his entire family on board for support.

Markets change companies, companies change markets. Our objective: To give our customers and suppliers the security of a reliable partner at their side, a partner that is number 1 worldwide in customer success orientation.

To find great ideas, new ways must sometimes be explored. Trying something new and linking different ideas. That’s how KASTO innovations develop, innovations, which bring real results for the customer.

For KASTO, our future means securing our customers’ futures. Subsequently, short-term success has never been a company objective. Instead, KASTO always plans to be successful in the long run and to keep all services on a sustainable high level.

It all starts with an idea: How are processes improved? Which of those improvements really help companies to work more efficiently? How can KASTO improve the profitability of their customers?

Being responsible for a certain part requires expertise. To be responsible for the whole requires courage and the ability to manage interconnected problems seamlessly.

Metal saws from KASTO are marathon runners. The proof is in tool life and machine lifetime. Therefore, an investment in a KASTO machine means real company value, which still can be seen if the machine is sold.

It is only natural for a successful company to work in the present and look to the future. Our motivation for providing long-term, outstanding performance is based on the success and positive feedback from our customers.

Our customers

In addition, customers from different industries, i.e. steel mills, shipyards, schools and research facilities.
