Each caster produced by Shangxin has undergone rigorous testing and strictly abides by the relevant national regulations to ensure the quality of the casters before it goes on the market. Today I will show you what tests are generally done on casters?
1. Caster rotation performance test
Put the single wheel on the horizontal experimental plane and let it load the maximum load specified, then tie a rope parallel to the experimental surface, gradually increase the weight through the pulley, and measure the weight of the wheel to 1/2 weight.
2. Rotation performance test
In the rotation performance test, the casters are fixed on the support arm of the testing machine, and the starting angle is adjusted to 90 ° against the wheels of the casters, so that the casters are rotated under the maximum load, and the rotation tendency is observed.
3. Walking performance test
Walking performance test, let the caster load the maximum load, and walk on the steel turntable at a certain speed to check whether the wheel surface is cracked or peeled, whether it has a smooth rotation, and whether there is abnormal noise.
4. Other tests
Other tests include salt spray test, drop test, plastic impact test, hardware and plastic hardness test, braking times test, etc.
