CARSUN CASTER Comprehensive and strict experiments to ensure the performance and safety of casters

Dongguan Carsun Caster Co., Ltd. 

Castors need to undergo a series of strict quality and performance tests before leaving the factory to ensure that their quality and performance meet the standards. The following are the main experiments that casters may need to undergo before leaving the factory:

Load capacity experiment:

Experimental purpose: To test the maximum load that the casters can withstand.

Experimental method: Place a certain weight object on the casters and observe its stability and load-bearing capacity.

Note: This experiment needs to be conducted based on the rated load of the casters and the expected application scenario.

Wear resistance test:

Experimental purpose: To evaluate the wear resistance of casters under different surfaces and usage conditions.

Experimental method: Place the casters on a specific friction surface and simulate repeated rolling under different usage conditions.

Attention: This experiment needs to consider the influence of different ground materials, humidity, temperature, and other factors on the wear resistance of the casters.

Wear test:

Experimental purpose: To evaluate the rolling resistance and friction of the casters.

Experimental method: Place the casters on a specific rolling platform and measure their rolling force and resistance.

Attention point: This experiment helps optimize the design and material selection of casters to reduce rolling resistance and friction.

Salt spray experiment:

Experimental purpose: To test the corrosion resistance of casters in harsh environments.

Experimental method: Expose the casters to different chemical substances or humidity environments and observe the corrosion on their surfaces.

Note: This experiment helps evaluate the durability of casters in humid, salt spray, and other environments.

Impact resistance test:

Experimental purpose: To evaluate the performance of casters under impact.

Experimental method: Install the casters vertically upside down on the experimental platform, so that a weight equal to the maximum load capacity of the casters can freely fall from a height of 200mm and impact the edges of the casters. If it is two wheels, both wheels should impact simultaneously.

Note: This experiment helps evaluate the stability and durability of the casters when subjected to unexpected impacts.

Lifetime experiment:

Experimental purpose: To evaluate the lifespan of casters under long-term use and repeated stress.

Experimental method: Place the casters under simulated usage conditions and conduct continuous rolling and load tests to evaluate their lifespan and performance stability.

Note: This experiment helps predict the service life and maintenance cycle of casters in practical applications.

Resistance performance experiment:

Experimental purpose: To evaluate the conductivity of the casters.

Experimental method: Place the casters on a metal plate insulated from the ground, keep the wheel edges in contact with the metal plate, load 5% to 10% of the rated load on the casters, and use an insulation resistance tester to measure the resistance between the casters and the metal plate.

Attention point: This experiment helps to ensure that the casters can function properly in situations that require conductivity, such as medical equipment.

Static load test:

Experimental purpose: To evaluate the ability of casters to withstand loads in a stationary state.

Experimental method: Fix the casters with screws on a horizontally smooth steel experimental platform, apply a certain force (such as 500 lbs) along the center of gravity direction of the casters and maintain it for a certain period of time (such as 24 hours), and then check the condition of the casters.

Attention point: This experiment helps to ensure that the casters can withstand the expected load without damage in a stationary state.

These experiments are crucial in the manufacturing process of casters, ensuring that their performance, quality, and durability meet standard requirements and meet the needs of various application scenarios.
