Our 'factory tour' shows the main steps of the production process for HEXADUR® tires, which are produced at our ISO 9001-2008 certified production facilities:
A solid, high-strength, precision-machined steel ring provides the base for the application of the HEXADUR® wear protection layer.
The hexagonal tiles are applied to the base ring.
The ring is transferred into a sheet-metal capsule. The lid is welded gas-tight onto the capsule.
Homogenized metal powder is filled into the capsule and densified on a vibration table. This powder later forms the tough interspace material.
The gas-tight capsule is evacuated and sealed. Tightness is checked using a helium leakage test.
The compound body is then exposed to high temperature and pressure (HIP technology).
The capsule is removed by machining on a vertical lathe.
The required final material properties are achieved by heating the HEXADUR® tire to approx. 1,000 °C followed by rapid quenching.
