Production

HEXADUR® - unique design and high-tech production

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:

Base Ring

a solid, high-strength, precision-machined steel ring provides the base for the application of the hexadur® wear protection layer.

Tile Assembly

亚洲杯欧赔the hexagonal tiles are applied to the base ring.

Capsule Assembly

the ring is transferred into a sheet-metal capsule. the lid is welded gas-tight onto the capsule.

Powder Filling

亚洲杯欧赔homogenized metal powder is filled into the capsule and densified on a vibration table. this powder later forms the tough interspace material.

Evacuating and Sealing

亚洲杯欧赔the gas-tight capsule is evacuated and sealed. tightness is checked using a helium leakage test.

Hot Isostatic Pressing (HIP)

亚洲杯欧赔the compound body is then exposed to high temperature and pressure (hip technology).

Removing the Capsule

亚洲杯欧赔the capsule is removed by machining on a vertical lathe.

Hardening

亚洲杯欧赔the required final material properties are achieved by heating the hexadur® tire to approx. 1,000 °c followed by rapid quenching.
