Our history
1970: Founding

Anton Unterwurzacher sets up a metalworking shop with five employees in Kuchl near Salzburg.

I didn’t really think about the direction the business would take. My goal was always to develop products according to customer specifications. The customer was always king. We certainly had to pay our dues along the way – the fact that the business developed as it did was partially due to luck.

The success story continues

Anniversary 2020 - 50 years UNTHA
  • UNTHA GENIUS: The intelligent condition monitoring tool GENIUS, newly developed by UNTHA, is the brain of every shredding machine. All the necessary operating and process data can be called up online in real time.

  • ZR2400: UNTHA presents a new 2-shaft shredder for the processing of waste and metals. This shredder was specially designed for coarse pre-shredding.

  • Customer service: The UNTHA Service Competence Center guarantees the extensive services that existing customers can expect from their reliable partner.

  • New RC cutting system: With the RC cutting unit for the XR class, UNTHA has developed a new type of knife geometry with improved intake behavior, with which, among other things, particularly high throughput rates are possible.
