Punching die and tooling design

At Donako, we pay particular attention to ensuring the high quality and reliability of the punching dies and tools we design, which is reflected in the many positive customer references we’ve received.

For years, our R&D department has used modern techniques to design and validate our  tools which means that we can use the most modern materials to build them.
