How to distinguish strengths and weaknesses with hard labels
Abstract：With the development of the times, technology is advancing rapidly, and the types of hard labels on the market are also constantly changing.
With the development of the times, technology is advancing rapidly, and the types of hard labels on the market are also constantly changing. However, the quality of these labels varies greatly. Due to intense competition, the prices also differ significantly.
So, regarding the pros and cons of hard labels, I can roughly distinguish them from the following aspects:
2. Outer material: The standard hard label material should be brand-new ABS engineering plastic. Due to its stable performance, strong plasticity, good toughness and strength, and good resistance to damage, it is suitable as the outer material for hard labels. Generally speaking, white or gray are better choices as they will use new ABS materials. However, black hard labels may contain some recycled materials, which are more brittle and have poorer resistance to damage. The identification method is usually to crush the hard label and then bend it back and forth to check its flexibility.
2. Electrical Performance: Refers to the internal coil circuit. Good coils are made using pure copper enameled wire. However, due to the rapid increase in the price of copper, some manufacturers may use copper-clad steel wire and aluminum wire instead. This will make it difficult to stabilize the Q value of the coil, directly affecting the oscillation frequency of the label, which may lead to a decrease in sensitivity and may result in missed detections in practical applications.
3. Lock core structure: The standard lock core structure should be three-pin positioning. The lock core structure consists of a sleeve, three-hole top column and steel balls. The three pins have excellent stability, but using three pins in the manufacturing process will be more complex and involve more procedures. Therefore, some manufacturers, in order to increase production and save costs, adopt four pins. Some even omit the three-hole top column. This results in unstable steel pins and easy detachment of the steel parts. Poor lock core processing can lead to unsmooth unlocking or locking problems; in addition, the tensile strength of the lock pins cannot meet the standard. Moreover, the selection of the spring force will also have certain influences.
In conclusion, generally speaking, one can determine whether a hard label is qualified by the above three aspects. However, due to the limitations of the project, there is currently no industry standard or national standard. Therefore, customers need to have a better understanding of the professional knowledge in this field. Of course, you get what you pay for. When the price difference is significantly large, one should also carefully consider and distinguish.
