Equipment Highlights

Bi-axial Test

Currently, our Marka bi-axial test bench is the only one of its kind in Taiwan.

Bi-axial Test

The Nürburgring is located in Nürburg, Rhineland-Palatinate, Germany. In 1920s, the ring was built around a small village and medieval castle in Nürburg near the Eifel Mountain. This ring is challenging as it is a very long and runs across complex terrains. Apart from being considered as the world’s most demanding ring built for car racing, it is also the field for the durability and performance tests before mass production of new car models. The bi-axial test simulates the Nürburgring to test wheels on the toughest road surface and load-carrying condition and thereby validate if the wheel design and manufacture meet the requirements for the toughest road surface.

Bending Fatigue Test

Bending Fatigue Test

The bending fatigue test simulates the bending moment that wheels must resist under repeated fatigue to verify the lifespan of spokes and the hub and thereby ensure that no cracks or loosened bolts (nuts) or other vehicular hazards will occur.
