Quality cuts costs: our machines turn a tidy profit

To date, Plasser & Theurer has supplied 17,700 machines. Most of them are still in operation. This attests to the quality of the machines and the value of our Customer Services’ life-long machine and fleet support. Plus, it proves that high quality ensures high cost-efficiency: machines that have been in operation for 20 or 30 years paid off years ago.
