The main components of the anti-theft hard tag are "lock" and "coil". The quality of the label can be directly distinguished by distinguishing the quality of the two. Let's analyze the lock first. Most anti-theft hard tags are independent locks. Generally, this Manufacturers of independent locks will go to other manufacturers that specialize in independent locks to process ready-made locks. Because many independent lock manufacturers are small in scale, the processing environment is relatively bad. For the most important part of the hard tag, the requirements for the lock head are relatively strict, which will directly affect its future use, whether it can be unlocked smoothly and the life of the lock head. In the independent lock head, it is often seen that the lock cannot be opened due to the poor processing environment or the use of poor-quality rust-prone iron balls with too many impurities or rusty adhesion, which eventually indirectly damages the product.
The coil is the core component to analyze whether the whole anti-theft system is good or bad. The coil is actually a kind of LC oscillating circuit. In order to reduce the cost of inferior labels, the original copper wire will be replaced by copper-clad aluminum wire or aluminum wire directly to reduce the cost. Therefore, this kind of label is susceptible to moisture and oxidation, which affects the service life. In the process of label processing, there will be a process of bonding the labels with an ultrasonic machine. This will cause a momentary high temperature. Inferior labels generally use plastic-wrapped wires. The melting point of plastic is very low, so the process of ultrasonically bonding labels is easy. The coil is melted to cause a short circuit, which directly affects the yield of the product. Therefore, when purchasing anti-theft tags, you must choose carefully, ask more, read more, and choose more to buy quality-assured anti-theft hard tags.
