Author: LPHY –Professional casters manufacturer,
A large number of software for industrial casters not only promote the progress of society, but also have a great impact on the development of our lives; for example, the casters in our furniture, the casters in chairs, and some large-scale machines in the industry are today for convenience. Movement is already based on casters, and it is incredible how much convenience the software of casters has brought us. Among the casters we see in our lives, it is not that it can be used for software through production, but it has also undergone a series of tests to be able to pack, package, and software. It is true that the industrial caster manufacturers have different test requirements for casters of different materials. Let's see which methods are used to test the casters, and finally become qualified casters.
1. Come and go wear test:
The wear and tear test of the casters simulates the actual rolling situation of the casters in the daily software. It is divided into two types: the suffocating obstacle test and the no suffocating obstacle test. During the test, no casters or other parts are allowed to leave. Each caster should be able to drive its flat function, and the rolling of the rear caster should be realized after the test, and the rolling around the axis or the braking effect should not be damaged.
2. Rolling resistance and rotation resistance measurement:
When the caster moves or wants to control its direction of travel, the force must be transmitted to the caster through the object and overcome the inevitable resistance. The size of the resistance depends on: load, wheel diameter, wheel material, wheel surface pattern, and the situation of the ground where the caster rotates. Wait.
3. Resistance function test:
When testing this function, the caster should be kept dry and clean. Place the caster on a metal plate insulated from the ground, keep the edge of the wheel in contact with the metal plate, and load 5% to 10% of its nominal load on the caster.
Use an insulation resistance value tester (nominal open circuit voltage is 500V, the measured resistance value fluctuates within 10% and the cost on the product does not exceed 3W) to measure the resistance value between the caster and the metal plate. Regarding conductive casters, the resistance value should not be greater than 104 ohms, while the resistance of antistatic casters should be between 105 ohms and 107 ohms.
4. Attack test:
Any item may cause collision and vibration due to transportation, software, storage, etc., so that the product cannot be placed in the software for a certain period of time. Furniture is often easily hit because of its large size and weight, and the casters at the bottom determine whether the furniture is placed smoothly. It should have a good anti-attack function.
5. Static load test:
The casters should always run steadily on the ground, but that is almost a purely superficial condition. On uneven surfaces, or when crossing thresholds, tracks and potholes, the casters leave the ground instantaneously. Therefore, when they are suddenly overloaded, about 3 of the 4 casters touch the ground, and they must carry the load of all furniture.
Through the above tests, we can find that even if the surface is simple and not very large, it can become a qualified caster product through these test capabilities. When producing the product, we should control it step by step according to the above series of test methods, which is not only to guarantee the quality of the product, but also to be responsible for our product.
