KoCo Casters Factory not only engages in independent production but also provides OEM services, independently designing and developing casters based on customer drawings and specifications.
With over 20 years of experience, we provide high-quality solutions.
From raw material sourcing for wheels and brackets to component production and final assembly, every process is carried out systematically under supervision.
High efficiency and high quality are our guiding principles.
Before each batch production run for a customer, KoCo caster factory conducts quality testing on the casters according to international standard ISO.
The testing is tailored to the customer's specific needs, and test videos and reports are provided. Today's test was a brake fatigue test, totaling 5000 cycles.
Detailed data is as follows：
This caster is 5 inches in size, made of nylon, and has a swivel design with brakes.
Test Content:
2. Test Method: Apply force to the brake pedal sequentially in both horizontal and vertical directions to achieve the "brake hold/release" action of the brake pads;
3. Number of Braking Actions: 5000 times;
4. Braking Frequency: 10 cycles/min;
Test Record：
No. | Starting Time | Ending Time | Times | Post-test status |
1 | 26.1.22-10:20 | 26.1.23-10:40 | 5000 | The brake lever moves slightly, and the brakes are working well. |
Test Result：
Test Item | Testing standards (within 5000 tests) | Result |
Brake pads Brake pedal | Maintain elasticity; brakes function normally. | Qualified |
The pedal moves slightly, but the brakes function normally. | Qualified |

Ps： The international standard ISO 22883-2004 specifies "fatigue testing of brakes and locking devices" for casters and wheels used in transport devices with speeds below 1.1 m/s (4 km/h). It stipulates that if the brakes and locking devices do not show any wear or continuous deformation that would adversely affect their function, the test is considered passed, provided that the test is conducted at 10 cycles per minute for a total of 5000 cycles.
KoCo caster factory is equipped with comprehensive caster testing equipment, including routine tests such as brake fatigue testing, walking tests, and freezing and high-temperature tests. KoCo is committed to providing customers with high-quality casters, and its testing equipment is continuously optimized and upgraded to meet customer needs and support the expansion of the caster market.
