To test the durability and resistance of the Quietex™ bumper by closing an ordinary kitchen cabinet door for duration of 100,000 cycles.
- Kitchen cabinet
- Pneumatic closing device with a cycle counter
- Two Quietex™ bumpers
- Various hardware and brackets (used for stability and spacing)
Set up the text fixture shown
When the cycle counter matches 100,000 disconnect the air and power supply lines. Observe the physical state of the bumpers.
- Check to make sure that when the cabinet door is in its fully closed position the two Quietex™ bumpers are being compressed (Figures 2 & 5).
- Once the proper spacing has been established, make sure that the cycle counter reads all zeros (Figure 3a & 3b).
- Connect the air and power supplies lines to the pneumatic closing device.
- The test will begin once those lines have been connected. The closing device will start and the durability test will initiate.
After 85,302 cycles, the bottom hinge on the cabinet door had snapped. The Quietex™ bumpers showed no signs of losing their shape or resilience.
Since the bumpers showed no signs of wear or deformations at 85,302 cycles, we believe that the bumpers will perform the same at the 100,000 as they perform at the 85,302 cycles (Figure 4).
