How to distinguish the advantages and disadvantages of hard labels

With the development of the times, the science and technology are changing with each passing day, and the types of hard labels on the market are frequently updated, but the quality of the product is uneven. Due to fierce competition, the price varies greatly.

Then the advantages and disadvantages of hard labels can be roughly distinguished from the following aspects:

1. Exterior material: Standard hard label materials should be a new ABS engineering plastics. Because of its stable performance, strong plasticity, good toughness and strength, and good resistance, it is suitable for hard label shell materials. Generally speaking, it is better to use white or gray, because it will use new ABS materials, and the black hard label may be mixed with some recycling materials. Generally, the hard label can be smashed back and forth, and the flexibility can be distinguished.

2. Electrical performance: Refers to the internal coil circuit, the good coils will be made of pure copper paint lines, but because the price of copper materials has increased too fast, some manufacturers may use copper bag steel lines and aluminum wire materials, which will lead to the coil of the coil. The Q value is difficult to stabilize, directly affecting the oscillation frequency of the label, which can cause the sensitivity to decrease, and it may be missed in practical applications.

3. Locking core structure: The standard lock core structure should be positioned in Sanzhu. The lock core structure includes tile sets, three -hole top pillars and steel balls. The three beads have good stability, but the use of Sanzhu production will be complicated in the process. , There will be more procedures. Therefore, some manufacturers use four beads to increase the cost saving costs, and some even save the three -hole top pillar. This causes the unstable phenomenon of steel needle cards, and it is easy to fall off. If the lock core is not handled well, it can cause the unlocking unlocking or stuck; In addition, the choice of the strength of the spring will also have a certain impact.

In summary, it can generally determine whether a hard label is qualified from the above three aspects, but because of the limitations of the project, there is no industry standard or national standard, so customers need to learn more about this professional knowledge. Of course, one penny and one point of goods should be carefully considered and distinguished when the price difference is normal.
