Extrude Hone GmbH - Holzgünz

“Extrude Hone GmbH facility opened in February 2013 in Holzgünz, but the history of Extrude Hone in Germany started in 2000 with the move of the Electrochemical Machining (ECM) activities, which started in the 70’s and the one acquired from the Bosch Surftran Division, from the US to Buxheim in Germany.
In 2005, Extrude Hone acquired DIVA-Tec, followed by the VMB acquisition. In 2007, Extrude Hone merged the multiple German entities into Extrude Hone GmbH.
It’s the Extrude Hone Electrochemical Machining (ECM) Center of Excellence. We have engineering, machine manufacturing, tooling, spare manufacturing, and contract shop service capabilities.
It’s also the European service hub for our three technologies (TEM, ECM, and AFM).
The Contract Shop service offers Electrochemical Machining (ECM) and abrasive Flow Machining (AFM).”

Extrude Hone, the genuine Abrasive Flow Machining company offers much more.

We build machines, offer Contract Shop services, and provide aftermarket support for :

  • Abrasive Flow Machining / Extrude Honing (AFM)
  • MICROFLOW the Extrude Hone version of the Hydrogrinding.
  • Electrochemical Machining (ECM), Static or Dynamic
  • Thermal Deburring (TEM)

Finishing that encompasses Deburring, Polishing, Radiusing, Shaping, and Flow Tuning of metallic components plays an even more critical role in manufacturing.

And the task is made more challenging by compact designs, complex shapes, and difficult-to-machine materials.

Proper finishing of metallic components enhances the Safety, Reliability, and Efficiency, of the entire system you build, thus, increasing the value of your offering to your customers.
