A brief introduction to the method of distinguishing the quality of medical casters and how to ensure the quality of the industry


LPHY is a professional casters manufacturer in China

Medical casters represent the traditional shift from metal to plastic, driven primarily by system economics. Plastic compound materials for wheel hubs include a variety of resins and filler systems, from talc fillers to glass fibers to carbon fibers, to long glass and long carbon fibers, which provide increasing strength and practical impact resistance. TPEs, especially thermoplastic vulcanizates, provide the good compression set properties required for wheels.

Made from carbon black or other fillers and resins, these materials provide static-dissipative protection that improves the surface resistance of filled polymers.

How to distinguish the quality of medical casters:

1. From the appearance of the bracket of the medical caster, the steel plate bracket of the medical caster has a beautiful surface, no burrs, and the thickness must be uniform, thus ensuring the quality of the load;

2. Galvanizing the bracket of the medical caster: In order to prevent rust, the bracket is generally galvanized, and the galvanizing of the bracket of the medical caster should be uniform and shiny;

3. Welding of medical caster brackets: the welding of steel plates should be smooth, and there should be no leakage welding, leakage points, etc.;

4. The size of the commonly used wheels for medical casters;

5. Check the appearance of the medical caster: smooth surface, no bumps, uniform color, no obvious color difference;

6. Check the overall effect of the universal wheel: when the top plate rotates, each steel ball should be able to contact the surface of the steel plate, the force should be uniform, the rotation should be flexible, and there is no obvious pause;

7. Check the bearing quality of the medical caster: there should be no obvious jumping phenomenon when the medical caster rotates.

Any item may have collision and vibration due to transportation, use, storage, etc., and the product will be used for a certain period of time. The device is often vulnerable to impact due to its large size and weight, and the medical caster at the bottom determines whether the device is placed smoothly. It should have good impact resistance.

Medical casters should always run stably on the ground, however that is almost a purely theoretical state. On uneven surfaces, or over thresholds, tracks and pits, the medical casters briefly leave the ground. So when they are suddenly overloaded or when 3 of the 4 medical casters touch the ground, they must carry the load of the entire device.

The quality of medical caster products must be guaranteed. First of all, there must be a strict supervision system. The government must play the role of market supervision, and the frequency of sampling and testing should be larger to ensure that different batches of medical caster samples can be sampled and detected. Unqualified We must resolutely investigate and find the person in charge behind the products of the company, and punish them severely. Secondly, it is still necessary to rely on the market to play a role and establish a corporate credit scoring system similar to Taobao. This also requires the government to establish a sound corporate reputation and rely on the market’s own survival of the fittest function to eliminate those companies without market reputation. to play the role of market supervision. It is good to rely on the self-consciousness of the enterprise. The quality of the product determines the market share of the enterprise. Entrepreneurs must have a sense of social responsibility and mission, and promote the brand made in China to a higher level.

It can be seen that the quality of the medical caster industry still has the role of different forces. It is obvious that relying on the enterprise itself cannot solve the problem, but also relying on the government to rely on the market. After all, the role of the government and the market is quality supervision.
