Finite Element Analysis
We use 20+ years of wheel load FEA data to simulate different conditions and its effect on the wheel design, to see how to fine tune the design detail to maximize the final wheel strength.

Coordinate Measuring Check
We use CMM to check the initial wheels, production wheels, and end pieces. To make sure the wheel we develope and produce are consistent.

Tensil Test
At each production run. We take pieces out from the wheel to check the material strength and level of stress to make sure the material in the wheel meet all the requirement.

X-Ray Check
To ensure there are no porosity in the wheel. We use a X-Ray machine that is build-in to our production line to check inside of each wheel.

Hardness Check
Aluminum wheel go through many heat cycles. We check hardness to make sure wheels has been properly heat-treated.
![test-Radial-Fatigue-Test](https://9six9wheels.com/wp-content/uploads/2020/10/test-Radial-Fatigue-Test.jpg)
Radial Fatigue Test
We test the development wheels and production wheels on simulate road condition. Under dynamic load for millions and millions of cycles.
![Impact Test](https://9six9wheels.com/wp-content/uploads/2020/10/test-Impact-Test.jpg)
Impact Test
We test the development wheels and production wheels to simulate axial curb impact collision properties of the wheels.
![Bending Fatigue](https://9six9wheels.com/wp-content/uploads/2020/10/test-Bending-Fatigue-Test.jpg)
Bending Fatigue Test
We test the development wheels and production wheels to simulate dynamic bending fatigue to prolong stress with emphasis on bolt pattern, center bore, and spoke. resilience.
![Deformation Test](https://9six9wheels.com/wp-content/uploads/2020/10/test-Deformation-Test.jpg)
Deformation Test
To check the strength of the inboard rim against bad road condition. Inboard rim is the first impact point from the uneven road surface due to the vehicle suspension negative offset.
![Vibration Test](https://9six9wheels.com/wp-content/uploads/2020/10/test-Vibration-Test.jpg)
Vibration Test
To ensure our wheels and caps can sustain the vibrations.
![Accelerated Weather Test](https://9six9wheels.com/wp-content/uploads/2020/10/test-Accelerated-Weather-Test.jpg)
Accelerated Weather Test
Test the paint performance by using acclerated weathering test to simulated long term exposure to outdoor conditions, UV, wind, ice, sand, and dust.
![Corrosion Test](https://9six9wheels.com/wp-content/uploads/2020/10/test-Corrosion-Test.jpg)
Corrosion Test
We test corrosion to evaluate performance of wheel, cap matera,l and coating. To make sure our wheels can withstand long term capability under harsh conditions.
![Chipping Resistance Test](https://9six9wheels.com/wp-content/uploads/2020/10/test-Chipping-Resistance-Test.jpg)
Chipping Resistance Test
To determine the resistance of painted surface on wheels that have been impacted by gravel.
![Helium Leak Test](https://9six9wheels.com/wp-content/uploads/2020/10/test-Helium-Leak-Test.jpg)
Helium Leak Test
Each wheel is leak-proof checked by using the smallest gas molecule to ensure accuracy.
![Run Out and Balance Check](https://9six9wheels.com/wp-content/uploads/2020/10/test-Run-Out-and-Balance-Check.jpg)
Runout and Balance Check
We check each wheel for balance and run-out before packaging. Our fully automated run-out and balance machine check radial run-out, lateral run-out, static balance, and dynamic balance.
